Description

Technical Field

[0001] This invention relates to the field of instrument and equipment technology, specifically to a method, apparatus, equipment, and storage medium for removing grease from bearings. Background Technology

[0002] Grease in grease-lubricated bearings is a semi-solid lubricant made of base oil, thickener, and additives. When bearings are assembled, the grease inside is usually uneven. This uneven grease distribution can cause abnormal noises during equipment startup and at high or ultra-high speeds, and can lead to a significant increase in bearing temperature, resulting in serious malfunctions such as bearing damage and equipment failure. Therefore, there is an urgent need to provide a method to improve the uniformity of grease lubrication in grease-lubricated bearings. Summary of the Invention

[0003] In view of this, the present invention provides a method, apparatus, equipment and storage medium for grease removal from bearings, in order to solve the problem of uneven grease distribution in grease-lubricated bearings in related technologies.

[0004] In a first aspect, the present invention provides a method for removing grease from bearings, the method comprising:

[0005] Obtain the rated speed of the target bearing;

[0006] Based on the rated speed, the grease run information of the target bearing is determined, and the grease run information is used to characterize the grease run time of the target bearing at multiple target grease run speeds;

[0007] Obtain the bearing temperature threshold corresponding to the target bearing at multiple target grease run-off speeds;

[0008] Based on the grease-running information, the target bearing is subjected to grease-running, and the grease-running temperature of the target bearing is obtained;

[0009] If the heating rate is equal to the target heating rate and lasts for the target time before the grease running temperature reaches the bearing temperature threshold corresponding to each target grease running speed, then the grease running of the target bearing is terminated.

[0010] The bearing grease removal method provided in this invention improves the reliability of grease removal by determining the grease information of the target bearing based on its rated speed, i.e., the grease removal time at multiple target grease removal speeds. It also improves the prevention of bearing damage due to excessively high grease removal temperatures by acquiring the bearing temperature thresholds corresponding to these speeds. Furthermore, it provides the necessary conditions for determining the timing of grease removal by performing grease removal on the target bearing based on the grease removal information and acquiring the grease removal temperature. If the grease removal temperature reaches the bearing temperature threshold corresponding to each target grease removal speed, and the heating rate is equal to the target heating rate and remains at the target time, the grease removal process is terminated, thus improving the efficiency and uniformity of grease removal. In short, this bearing grease removal method can meet the requirements of ultra-high-speed operation of the target bearing, reduce grease removal time, improve grease removal efficiency, and effectively reduce the vibration value of the target bearing during operation.

[0011] In some optional implementations, determining the grease leakage information of the target bearing based on the rated speed includes:

[0012] Based on the rated speed, determine the minimum grease run-off speed, the maximum grease run-off speed, and the speed adjustment interval for the target bearing;

[0013] Based on the minimum oil-running speed, the maximum oil-running speed, and the speed adjustment interval, multiple target oil-running speeds and corresponding oil-running times for the target bearing are determined.

[0014] Based on the multiple target oil-running speeds and corresponding oil-running times, the oil-running information of the target bearing is determined.

[0015] The bearing grease removal method provided in this invention determines the minimum grease removal speed, the maximum grease removal speed, and the speed adjustment interval of the target bearing based on the rated speed, and then determines multiple target grease removal speeds and corresponding grease removal times for the target bearing, thus providing the necessary conditions for reliable grease removal of the target bearing.

[0016] In some optional implementations, determining the grease leakage information of the target bearing based on the rated speed includes:

[0017] Obtain the resonance point of the target bearing during the grease run-through process, and determine the speed range corresponding to the resonance point;

[0018] Based on the rated speed and the speed range corresponding to the resonance point, the grease runoff speed range of the target bearing is determined;

[0019] Based on the aforementioned oil-running speed range, the minimum oil-running speed, the maximum oil-running speed, and the speed adjustment interval of the target bearing are determined.

[0020] Based on the minimum oil-running speed, the maximum oil-running speed, and the speed adjustment interval, multiple target oil-running speeds and corresponding oil-running times for the target bearing are determined.

[0021] Based on the multiple target oil-running speeds and corresponding oil-running times, the oil-running information of the target bearing is determined.

[0022] The bearing grease removal method provided in this invention obtains the resonance point of the target bearing during the grease removal process, determines the speed range corresponding to the resonance point, and determines the grease removal speed range of the target bearing based on the rated speed and the speed range corresponding to the resonance point. This avoids the situation where the grease removal effect is reduced due to resonance when the target bearing is grease removed within the speed range corresponding to the resonance point. Based on the grease removal speed range, the minimum grease removal speed, the maximum grease removal speed, and the speed adjustment interval of the target bearing are determined, thereby determining multiple target grease removal speeds and corresponding grease removal times for the target bearing, providing the necessary conditions for reliable grease removal of the target bearing.

[0023] In some optional implementations, performing grease removal on the target bearing based on the grease removal information includes:

[0024] Obtain the speed adjustment time between the multiple target fat-burning speeds;

[0025] The target bearing is subjected to grease removal based on the speed adjustment time and the grease removal information.

[0026] The bearing grease removal method provided in this embodiment of the invention obtains the speed adjustment time between multiple target grease removal speeds, and performs grease removal on the target bearing based on the speed adjustment time and grease removal information, so as to further improve the efficiency and reliability of grease removal on the target bearing.

[0027] In some optional embodiments, the step of ending the grease run on the target bearing if the heating rate is equal to the target heating rate and lasts for a target time before the grease run temperature reaches the bearing temperature threshold corresponding to each target grease run speed includes:

[0028] Obtain the grease run temperature and heating rate of the target bearing at each of the target grease run speeds;

[0029] The oil run-off temperature is compared with the corresponding bearing temperature threshold to obtain the temperature comparison result;

[0030] If the temperature comparison result indicates that the running temperature is less than the corresponding bearing temperature threshold, then the heating rate corresponding to the running temperature is obtained and timed.

[0031] If the heating rate is equal to the target heating rate and the time reaches the target time, then the grease application to the target bearing is terminated.

[0032] The bearing grease removal method provided in this embodiment of the invention obtains the grease removal temperature and heating rate of the target bearing at various target grease removal speeds, compares the grease removal temperature with the corresponding bearing temperature threshold, and obtains the heating rate corresponding to the grease removal temperature and times it when the grease removal temperature is lower than the corresponding bearing temperature threshold. If the heating rate is equal to the target heating rate and the time reaches the target time, the grease removal of the target bearing is ended, thereby improving the uniformity and balance of grease removal of the target bearing.

[0033] In some optional embodiments, the step of ending the grease run on the target bearing if the heating rate is equal to the target heating rate and lasts for a target time before the grease run temperature reaches the bearing temperature threshold corresponding to each target grease run speed includes:

[0034] If the heating rate is equal to the target heating rate and lasts for the target time before the running temperature reaches the bearing temperature threshold corresponding to each target running speed, then obtain the running current corresponding to the maximum running speed among the multiple target running speeds, and the current threshold.

[0035] Compare the target fat-burning current with the current threshold;

[0036] If the target grease runner current is less than the current threshold, the grease runner process for the target bearing is terminated, and the grease runner qualification information for the target bearing is output.

[0037] The bearing grease removal method provided in this embodiment of the invention, if the grease removal temperature is equal to the target heating rate and lasts for a target time before reaching the bearing temperature threshold corresponding to each target grease removal speed, then the grease removal current corresponding to the maximum grease removal speed among multiple target grease removal speeds, and the current threshold, are obtained. When the target grease removal current is less than the current threshold, the grease removal of the target bearing is terminated, and the grease removal qualification information of the target bearing is output, so as to improve the accuracy of judging the grease removal effect of the target bearing.

[0038] In some optional implementations, the method further includes:

[0039] If the heating rate is less than the target heating rate before the running temperature reaches the bearing temperature threshold corresponding to each target running speed, then the time of the target bearing at the target running speed and the heating time from the heating rate to the target heating rate are obtained.

[0040] If the sum of the time at the target oil-running speed and the heating time equals the oil-running time, then the oil-running process on the target bearing ends when the time at the target oil-running speed reaches the oil-running time.

[0041] The bearing grease removal method provided in this embodiment of the invention, if the heating rate is less than the target heating rate before the grease removal temperature reaches the bearing temperature threshold corresponding to each target grease removal speed, then the time of the target bearing at the target grease removal speed and the heating time from the heating rate to the target heating rate are obtained. Based on the relationship between the sum of the time of the target bearing at the target grease removal speed and the heating time and the grease removal time, the grease removal of the target bearing is terminated, thereby improving the reliability of the grease removal of the target bearing.

[0042] Secondly, the present invention provides a bearing grease removal device, the device comprising:

[0043] The speed acquisition module is used to acquire the rated speed of the target bearing;

[0044] The information determination module is used to determine the grease run-off information of the target bearing based on the rated speed, wherein the grease run-off information is used to characterize the grease run-off time of the target bearing at multiple target grease run-off speeds;

[0045] The threshold acquisition module is used to acquire the bearing temperature threshold corresponding to the target bearing at multiple target grease running speeds;

[0046] A temperature acquisition module is used to perform grease removal on the target bearing based on the grease removal information and to acquire the grease removal temperature of the target bearing.

[0047] The bearing grease running module is used to terminate the grease running process on the target bearing if the heating rate is equal to the target heating rate and lasts for a target time before the grease running temperature reaches the bearing temperature threshold corresponding to each target grease running speed.

[0048] The bearing grease removal device provided in this invention improves the reliability of grease removal by determining the grease information of the target bearing based on its rated speed, i.e., the grease removal time at multiple target grease removal speeds. It also improves the avoidance of bearing damage due to excessively high grease removal temperatures by acquiring the bearing temperature thresholds corresponding to the target bearing at multiple target grease removal speeds. Furthermore, by performing grease removal on the target bearing based on the grease removal information and acquiring the grease removal temperature, it provides the necessary conditions for confirming the timing of grease removal. If the grease removal temperature reaches the bearing temperature threshold corresponding to each target grease removal speed, and the heating rate is equal to the target heating rate and lasts for the target time, the grease removal on the target bearing is terminated, thus improving the efficiency and uniformity of grease removal.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] In the technology related to grease-lubricated bearings, users often encounter uneven lubrication during bearing assembly because the grease inside is a semi-solid lubricant made of base oil, thickener, and additives. This uneven grease distribution can cause abnormal noises during equipment startup and at high or ultra-high speeds, and can lead to a significant increase in bearing temperature, resulting in serious malfunctions such as bearing damage and equipment failure.

[0060] Based on this, embodiments of the present invention provide a bearing grease removal method, apparatus, computer equipment, and storage medium. The method involves acquiring the rated speed of the target bearing, determining grease removal information based on the rated speed, and using this grease removal information to characterize the grease removal time of the target bearing at multiple target grease removal speeds; acquiring the bearing temperature thresholds corresponding to the target bearing at the multiple target grease removal speeds; performing grease removal on the target bearing based on the grease removal information and acquiring the grease removal temperature of the target bearing; and ending the grease removal process if, before reaching the bearing temperature threshold corresponding to each target grease removal speed, the heating rate is equal to the target heating rate and lasts for the target time.

[0061] This embodiment provides a method for removing grease from bearings, which can be used in instruments and equipment. Figure 1 This is a flowchart of a bearing grease removal method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0062] Step S101: Obtain the rated speed of the target bearing.

[0063] The rated speed of the target bearing can be determined based on its calibration information. By obtaining the rated speed of the target bearing, the necessary conditions are provided for determining the grease running speed range of the target bearing.

[0064] For example, when performing grease removal on a target bearing, the target bearing is first installed in the corresponding position on an instrument (such as a molecular pump) so that the target bearing can be rotated by a DC brushless motor, the molecular pump body, and the main shaft, and grease removal can be performed.

[0065] Step S102: Based on the rated speed, determine the grease run-out information of the target bearing. The grease run-out information is used to characterize the grease run-out time of the target bearing at multiple target grease run-out speeds.

[0066] Specifically, by using the rated speed, the grease running time of the target bearing at multiple target grease running speeds is determined, so that the target bearing can be greased based on the corresponding grease running speed and grease running time, thereby improving the grease running efficiency of the target bearing.

[0067] In some optional implementations, the minimum and maximum grease-running speeds and speed adjustment intervals of the target bearing can be determined based on the rated speed; multiple target grease-running speeds and corresponding grease-running times of the target bearing can be determined based on the minimum, maximum, and speed adjustment intervals; and grease-running information of the target bearing can be determined based on the multiple target grease-running speeds and corresponding grease-running times. The grease-running direction of the target bearing includes at least the operating direction of the target bearing, that is, the grease-running direction of the target bearing includes directions in the same direction as the operating direction (e.g., clockwise) and directions opposite to the operating direction (e.g., counterclockwise).

[0068] Specifically, the minimum grease-running speed of the target bearing can be a first preset percentage of the rated speed, such as 10%; the maximum grease-running speed can be a second preset percentage of the rated speed, such as 110%. The maximum frequency interval corresponding to the speed adjustment interval can be kept within a preset speed interval, such as 200Hz. Larger frequency intervals will cause instability and abnormal noise during startup, and in this case, it is generally appropriate to choose a frequency interval of around 100Hz as the speed adjustment interval to increase the speed. At the same time, grease running at the rated speed is also necessary. That is, the speed adjustment interval is not completely fixed, but is adjusted based on the speed at which grease running is required. Therefore, the multiple target grease-running speeds of the target bearing include at least the minimum grease-running speed, the rated grease-running speed, the maximum grease-running speed, and the grease-running speed corresponding to the speed adjustment interval. When grease-running the target bearing at each target grease-running speed, the grease-running time of the target bearing at each target speed can be determined based on the influence of the target grease-running speed and time on the performance and temperature of the target bearing. In order to ensure the adequacy of grease running, the corresponding grease-running time can be used to repeat the grease running a target number of times.

[0069] For example, if the rated speed of the target bearing corresponds to a frequency of 500Hz, then the grease run information of the target bearing is determined as follows: the target bearing is accelerated from 0Hz to the minimum grease run speed (50Hz), maintained for 5 minutes, and then decelerated to 0Hz, repeated 5 times. The grease run duration can also be 6 minutes, and the number of repetitions is 12 times. Then, the grease run speed is increased to 100Hz, maintained for 10 minutes, and then decelerated to 0Hz, repeated 5 times (or 12 times). Then, the grease run speed is increased to 200Hz, maintained for 10 minutes, and then decelerated to 0Hz, repeated 5 times. Then, the grease run speed is increased to 400Hz, maintained for 1 minute, and then decelerated to 0Hz, repeated 5 times. Then, the grease run speed is increased to 500Hz, maintained for 1 minute, and then decelerated to 0Hz, repeated 5 times. Then, the grease run speed is increased to 600Hz, maintained for 1 minute, and then decelerated to 0Hz, repeated 5 times.

[0070] The bearing grease removal method provided in this invention determines the minimum grease removal speed, the maximum grease removal speed, and the speed adjustment interval of the target bearing based on the rated speed, and then determines multiple target grease removal speeds and corresponding grease removal times for the target bearing, thus providing the necessary conditions for reliable grease removal of the target bearing.

[0071] In some optional implementations, the resonant point of the target bearing during the grease run can be obtained, and the speed range corresponding to the resonant point can be determined; based on the rated speed and the speed range corresponding to the resonant point, the grease run speed range of the target bearing can be determined; based on the grease run speed range, the minimum grease run speed, the maximum grease run speed, and the speed adjustment interval of the target bearing can be determined; based on the minimum grease run speed, the maximum grease run speed, and the speed adjustment interval, multiple target grease run speeds of the target bearing and the corresponding grease run time can be determined; based on multiple target grease run speeds and the corresponding grease run time, the grease run information of the target bearing can be determined.

[0072] For example, if the resonant speed range of the target bearing during the grease run corresponds to a frequency of 400Hz, and the rated speed of the target bearing corresponds to a frequency of 500Hz, then the grease run information for the target bearing is determined as follows: the target bearing is accelerated from 0Hz to the minimum grease run speed (50Hz), maintained for 5 minutes, and then decelerated back to 0Hz, repeated 5 times. The grease run duration can also be 6 minutes, and the number of repetitions is 12 times. Then, the grease run speed is increased to 100Hz, maintained for 10 minutes, and then decelerated back to 0Hz, repeated 5 times. (This can be repeated 12 times); then increase the running speed to 200Hz, maintain for 10 minutes, then decrease to 0Hz, repeat 5 times; then increase the running speed to 385Hz, maintain for 1 minute, then decrease to 0Hz, repeat 5 times; then increase the running speed to 405Hz, maintain for 1 minute, then decrease to 0Hz, repeat 5 times; then increase the running speed to 500Hz, maintain for 1 minute, then decrease to 0Hz, repeat 5 times; then increase the running speed to 600Hz, maintain for 1 minute, then decrease to 0Hz, repeat 5 times. In other words, running must be performed on both sides of the resonance point.

[0073] The bearing grease removal method provided in this invention obtains the resonance point of the target bearing during the grease removal process, determines the speed range corresponding to the resonance point, and determines the grease removal speed range of the target bearing based on the rated speed and the speed range corresponding to the resonance point. This avoids the situation where the grease removal effect is reduced due to resonance when the target bearing is grease removed within the speed range corresponding to the resonance point. Based on the grease removal speed range, the minimum grease removal speed, the maximum grease removal speed, and the speed adjustment interval of the target bearing are determined, thereby determining multiple target grease removal speeds and corresponding grease removal times for the target bearing, providing the necessary conditions for reliable grease removal of the target bearing.

[0074] Step S103: Obtain the bearing temperature threshold corresponding to the target bearing at multiple target grease running speeds.

[0075] The bearing temperature thresholds corresponding to the target bearing at multiple target grease running speeds can be determined based on the magnitude of the influence of grease running time on bearing temperature at the corresponding target grease running speed. By setting the bearing temperature thresholds, grease running can be stopped when the target bearing's grease running temperature reaches the threshold, thereby preventing further grease running from affecting bearing quality.

[0076] Step S104: Perform grease running on the target bearing based on the grease running information, and obtain the grease running temperature of the target bearing.

[0077] Specifically, when performing grease running on the target bearing based on grease running information, the grease running temperature of the target bearing is obtained, and the grease running on the target bearing at the current target grease running speed is terminated based on the relationship between the grease running temperature of the target bearing and the bearing temperature threshold.

[0078] In some optional implementations, when performing grease running on the target bearing based on grease running information, the speed adjustment time between multiple target grease running speeds can be obtained; the target bearing is then grease run based on the speed adjustment time and the grease running information. The speed adjustment time and the rate of increase of the target grease running speed are related to the grease running temperature and performance of the target bearing.

[0079] The bearing grease removal method provided in this invention improves the efficiency and reliability of grease removal by acquiring the speed adjustment time between multiple target grease removal speeds and performing grease removal on the target bearing based on the speed adjustment time and grease removal information.

[0080] Step S105: If the heating rate is equal to the target heating rate and lasts for the target time before the running temperature reaches the bearing temperature threshold corresponding to each target running speed, then the running of the target bearing is terminated.

[0081] Specifically, the grease running temperature and heating rate of the target bearing at various target grease running speeds are obtained; the grease running temperature is compared with the corresponding bearing temperature threshold to obtain the temperature comparison result; if the temperature comparison result indicates that the grease running temperature is less than the corresponding bearing temperature threshold, the heating rate corresponding to the grease running temperature is obtained and timed; if the heating rate is equal to the target heating rate and the time reaches the target time, the grease running of the target bearing is ended to improve the uniformity and balance of grease running of the target bearing.

[0082] Temperature is the most important measurable variable for measuring the effectiveness of grease application and the condition of bearings during the grease application process. When performing grease application at a frequency corresponding to a target grease application speed, the temperature of the target bearing needs to be continuously monitored. Since the internal temperature of the target bearing is generally difficult to measure, the internal temperature can be evaluated by measuring the temperature of the outer ring. Under normal circumstances, the temperature continuously rises until it stabilizes. The grease application process is only possible if this stable temperature has not reached its upper limit. Therefore, after operating at the stable temperature for a period of time (i.e., the heating rate equals the target heating rate and the time reaches the target duration, such as 5-10 minutes), the grease application process at that target grease application speed can be considered complete.

[0083] The bearing grease removal method provided in this embodiment improves the reliability of grease removal by determining the grease information of the target bearing based on its rated speed, i.e., the grease removal time at multiple target grease removal speeds. It also improves the avoidance of bearing damage due to excessively high grease removal temperatures by acquiring the bearing temperature thresholds corresponding to the target bearing at multiple target grease removal speeds. Furthermore, it provides the necessary conditions for confirming the timing of grease removal by performing grease removal on the target bearing based on the grease removal information and acquiring the grease removal temperature. If the grease removal temperature reaches the bearing temperature threshold corresponding to each target grease removal speed, and the heating rate is equal to the target heating rate and lasts for the target time, then the grease removal on the target bearing is terminated, thus improving the efficiency and uniformity of grease removal.

[0084] In some optional implementations, if the heating rate is equal to the target heating rate and lasts for the target time before the running temperature reaches the bearing temperature threshold corresponding to each target running speed, then the running current corresponding to the maximum running speed among the multiple target running speeds, and the current threshold are obtained; the target running current is compared with the current threshold; if the target running current is less than the current threshold, then the running of the target bearing is terminated, and the running information of the target bearing is output as qualified.

[0085] For example, the grease running speed on the target shaft side is maintained at the maximum grease running speed of 600Hz for 1 minute, then the speed is reduced to 0Hz. This is repeated 5 times. If the grease running current corresponding to the maximum grease running speed in the target grease running speed is less than the current threshold (1A), then the grease running of the target bearing is ended, and the grease running qualification information of the target bearing is output.

[0086] The bearing grease removal method provided in this embodiment of the invention, if the grease removal temperature is equal to the target heating rate and lasts for a target time before reaching the bearing temperature threshold corresponding to each target grease removal speed, then the grease removal current corresponding to the maximum grease removal speed among multiple target grease removal speeds, and the current threshold, are obtained. When the target grease removal current is less than the current threshold, the grease removal of the target bearing is terminated, and the grease removal qualification information of the target bearing is output, so as to improve the accuracy of judging the grease removal effect of the target bearing.

[0087] In some optional implementations, instead of monitoring the running temperature, the running current corresponding to the maximum running speed among multiple target running speeds, as well as the current threshold, can be directly obtained; the target running current can be compared with the current threshold; if the target running current is less than the current threshold, the running of the target bearing can be terminated, and the running information of the target bearing can be output, thereby further improving the efficiency of judging the running of the target bearing.

[0088] In some optional implementations, if the heating rate is less than the target heating rate before the running temperature reaches the bearing temperature threshold corresponding to each target running speed, then the time of the target bearing at the target running speed and the heating time from the heating rate to the target heating rate are obtained; if the sum of the time of the target bearing at the target running speed and the heating time is equal to the running time, then the running of the target bearing is terminated when the time at the target running speed reaches the running time.

[0089] The bearing grease removal method provided in this embodiment of the invention, if the heating rate is less than the target heating rate before the grease removal temperature reaches the bearing temperature threshold corresponding to each target grease removal speed, then the time of the target bearing at the target grease removal speed and the heating time from the heating rate to the target heating rate are obtained. Based on the relationship between the sum of the time of the target bearing at the target grease removal speed and the heating time and the grease removal time, the grease removal of the target bearing is terminated, thereby improving the reliability of the grease removal of the target bearing.

[0090] In some optional implementations, if the heating rate is greater than the target heating rate before the running temperature reaches the bearing temperature threshold corresponding to each target running speed, it is necessary to allow a certain period of cooling (generally reducing by 10-15°C) before restarting the running process at this frequency. The running process is considered qualified once the temperature stabilizes below the upper limit of the absolute temperature.

[0091] Reference Figure 2The present invention also proposes a fat-running platform system, which includes a molecular pump, a host computer 12, a power supply 15, a fat-running drive module 14, and a mechanical pump 26. The controlled end of the fat-running drive module 14 is connected to the host computer 12, the power supply end of the fat-running drive module 14 is connected to the power supply 15, the output end of the fat-running drive module 14 is connected to the molecular pump, and the molecular pump is connected to the mechanical pump 26.

[0092] The molecular pump includes a pump casing 24, a pump body 23 housed within the pump casing 24, a main shaft 22 mounted on the pump body 23, and a counterweight structure 21 fitted onto the main shaft 22. The counterweight structure is a mechanical structure that enables the molecular pump to achieve low-frequency start-up by meeting minimum rotational inertia. The counterweight structure 21 is locked and fixed to the main shaft 22 by a nut, and a gasket and a sealing ring are provided between the nut and the counterweight structure 21. This effectively ensures the reliability of the assembly between the counterweight structure 21 and the main shaft 22 and improves the stability of the motor operation.

The host computer 12 can be electrically connected to the fat-running drive module 14 via a serial communication cable 13. The power supply 15 can be a 24V power supply. The fat-running drive module 14 can be electrically connected to the molecular pump via a molecular pump cable 16.
