Description

Technical Field

[0001] This invention relates to the field of transmission mechanism technology, and more specifically to a hybrid transmission device. Background Technology

[0002] In the existing technology, there are three main schemes for power transmission of power mechanisms. The first scheme is that the engine is directly connected to the hydraulic gear pump to directly provide hydraulic energy to the hydraulic system. The second scheme is that the engine provides mechanical energy to the actuator through a complex transmission mechanical structure such as pulleys, gearboxes, and drive shafts. The third scheme is that the hydraulic gear motor is directly connected to high-speed rotating actuators such as fans and cutter heads through bearing housings. All three schemes have many drawbacks.

[0003] The first solution has the following drawbacks: 1. The engine speed is too high, which can easily damage the hydraulic gear pump. Under high-speed operating conditions, the heat generated by the hydraulic gear pump will greatly affect its service life, thus affecting the performance and lifespan of the entire hydraulic system; 2. The installation requirements for the hydraulic gear pump are high and limited by the installation space. Custom-made special bearing mounting brackets are required, which are difficult and costly to manufacture; 3. Hydraulic control valves and pressure valves need to be added to the hydraulic system to achieve remote control and overload protection. Moreover, when the hydraulic system is not working, the gear pump continues to work, affecting the service life and energy efficiency of the entire hydraulic system.

[0004] The drawbacks of the second option are as follows: 1. The structure is complex, and the manufacturing difficulty and cost are relatively high; 2. The transmission efficiency is low, and the mechanical efficiency loss is relatively large due to the large number of transmission components; 3. It is not easy to realize remote control of the equipment.

[0005] The drawbacks of the third option are as follows: When the hydraulic system stops working or the hydraulic directional valve is in the neutral position and stops supplying oil to the hydraulic gear motor, the high-speed rotating cooling fan or the cutter head and other actuators will continue to rotate due to inertia, which will continue to drive the hydraulic motor to continue rotating. Since the hydraulic system has stopped supplying oil to the hydraulic gear motor, the motor's continued rotation will have a significant impact on the motor's operation and even the entire hydraulic system.

[0006] Therefore, a new transmission device is urgently needed to solve the problems existing in the above transmission process. Summary of the Invention

[0007] Therefore, the present invention provides a hybrid transmission device to solve the above-mentioned problems in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] According to a first aspect of the present invention, a hybrid transmission device includes an electromagnetic chuck, a pulley, a transmission shaft, a bearing bracket, and a hydraulic gear pump, wherein the electromagnetic chuck is connected to one end of the transmission shaft, and the electromagnetic chuck is coaxial with the transmission shaft;

[0010] The pulley is sleeved on the connector of the electromagnetic chuck, and the pulley is rotatably connected to the connector of the electromagnetic chuck. The pulley and the electromagnetic chuck are coaxial.

[0011] The end of the drive shaft opposite to the electromagnetic chuck is connected to the drive gear of the hydraulic gear pump.

[0012] The drive shaft is rotatably mounted inside the bearing bracket, and the hydraulic gear pump is mounted on the bearing bracket.

[0013] Furthermore, it also includes a coupling sleeve, which is disposed at the connection between the transmission shaft and the drive gear shaft.

[0014] Furthermore, the coupling sleeve is an involute spline connecting sleeve.

[0015] Furthermore, the drive shaft is a tapered shaft.

[0016] Furthermore, the bearing bracket is provided with a mounting base, and the mounting base is provided with mounting holes.

[0017] Furthermore, there are two mounting bases, which are symmetrically arranged along the axis of the bearing bracket.

[0018] Furthermore, the drive shaft and the electromagnetic chuck are connected by bolts.

[0019] Furthermore, the hydraulic gear pump is equipped with an overflow valve.

[0020] Furthermore, the hydraulic gear pump is provided with an oil inlet pipe joint and an oil outlet pipe joint on both sides respectively.

[0021] Furthermore, both the inlet pipe joint and the outlet pipe joint are high-pressure flange joints.

[0022] This invention has the following advantages: During use, the pulley is connected to the output shaft of the drive mechanism. When the electromagnetic chuck is energized, it magnetically attracts the pulley under magnetic force. When the pulley rotates, it drives the electromagnetic chuck to rotate, which in turn drives the drive shaft to rotate, and the drive shaft drives the hydraulic gear pump. The entire device has normal transmission function. When the electromagnetic chuck is de-energized, it is not magnetically attracted to the pulley. When the pulley rotates, it spins freely and does not drive the electromagnetic chuck to rotate. The entire device does not have transmission function. The entire device can be remotely controlled by turning the electromagnetic chuck on and off. The entire device has a compact structure, is easy to install and remotely control, has high transmission efficiency, and has good energy-saving effect. When connected to a hydraulic gear motor, this device can eliminate the influence and damage to the hydraulic system caused by the inertial operation of the high-speed rotating actuator.

[0031] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0032] Example 1

[0033] like Figures 1 to 5 As shown, a hybrid transmission device according to a first aspect embodiment of the present invention includes an electromagnetic chuck 1, a pulley 2, a transmission shaft 4, a bearing bracket 8, and a hydraulic gear pump 7. The electromagnetic chuck 1 is connected to one end of the transmission shaft 4, and the electromagnetic chuck 1 and the transmission shaft 4 are coaxial.

[0034] The pulley 2 is fitted onto the connector of the electromagnetic chuck 1, and the pulley 2 is rotatably connected to the connector of the electromagnetic chuck 1. Specifically, the pulley 2 and the electromagnetic chuck 1 are rotatably connected by a bearing. The pulley 2 and the electromagnetic chuck 1 are coaxial. The pulley 2 is made of magnetic material. The coil box 3 of the magnetic chuck 1 is located inside the pulley 2. The power cord of the coil box 3 is connected to a 12V or 24V DC power supply.

[0035] The end of the drive shaft 4 that is away from the electromagnetic chuck 1 is connected to the drive gear 6 of the hydraulic gear pump 7.

[0036] The drive shaft 4 is rotatably mounted inside the bearing bracket 8, and the hydraulic gear pump 7 is mounted on the bearing bracket 8. Specifically, the hydraulic gear pump 7 is fixed to the side of the bearing bracket 8 away from the pulley 2 by bolts. After the magnetic chuck 1 is powered on, the magnetic chuck 1 and the pulley 2 are attracted to each other, which drives the drive shaft 4 and the hydraulic gear pump 7 to rotate.

[0037] In this embodiment, it should be noted that the entire device can convert mechanical energy into hydraulic energy. The device is used as follows: a small pulley is installed on the output shaft of the motor or engine, and then connected to the pulley 2 of this device via a belt. This reduces the speed of the motor or engine to the ideal speed range required by the gear pump (1500-2000 r / min). Then, this device can be used for transmission, converting mechanical energy into hydraulic energy. Specifically, after the electromagnetic chuck 1 is energized, it will magnetically attract the pulley 2 under magnetic force, causing the pulley 2 to rotate. When the electromagnetic chuck 1 is powered on, it drives the transmission shaft 4 to rotate, which in turn drives the hydraulic gear pump 7 to operate. The entire device has normal transmission function. When the electromagnetic chuck 1 is powered off, the electromagnetic chuck 1 and the pulley 2 are in a non-magnetic state. When the pulley 2 rotates, it spins without driving the electromagnetic chuck 1 to rotate. The entire device does not have transmission function. The entire device can be remotely controlled by turning the electromagnetic chuck 1 on and off. When the power is off, the hydraulic gear pump 7 stops rotating, reducing the wear and energy consumption of the hydraulic gear pump 7, thereby improving the service life and energy efficiency of the entire hydraulic system.

[0038] Furthermore, the drive shaft 4 is a tapered shaft. By using a tapered shaft, a more stable connection can be achieved. The drive shaft 4 and the electromagnetic chuck 1 are connected by bolts.

[0039] The technical effects achieved by this embodiment are as follows: the entire device can be remotely controlled by turning the electromagnetic chuck on and off; the entire device has a compact structure, is easy to install and remotely control, has high transmission efficiency, and has good energy-saving effect; when connected to a hydraulic gear motor, the device can eliminate the influence and damage to the hydraulic system caused by the inertial operation of the high-speed rotating actuator.

[0043] In this embodiment, it should be noted that the coupling sleeve 5 is an involute spline connecting sleeve.

[0044] The technical effect achieved by this embodiment is that the coupling sleeve 5 is an involute spline connecting sleeve, which can ensure the installation accuracy of the hydraulic gear pump 7, and at the same time prevent the driving gear 6 of the hydraulic gear pump 7 from directly bearing the radial force transmitted from the pulley, thereby improving the service life of the gear pump.
