Description

TECHNICAL FIELD

[0001] The utility model relates to motor equipment technical field, concretely relates to an encoder mounting support. BACKGROUND

[0002] In the motor equipment technical field, permanent magnet motor is widely used in various precision motion control systems because of its high efficiency and energy saving. In these systems, the encoder as a key feedback element plays a crucial role. The encoder can monitor the position information of the motor in real time, ensure the precise control and speed stability of the motor, and thus improve the operation efficiency and precision of the whole system.

[0003] However, the traditional permanent magnet motor encoder mounting support design has obvious shortcomings. Usually, a plurality of encoders and transmission shafts are provided on these supports, and each encoder independently corresponds to a transmission shaft for speed monitoring. This design not only leads to a certain degree of waste of the computing resources of the encoder, but also in actual application, once a certain encoder fails or cannot work normally, it needs to be disassembled and replaced, which undoubtedly reduces the work efficiency and increases the maintenance cost.

[0004] In order to solve the above problems, the industry has been exploring more efficient and practical encoder mounting support design schemes. The ideal scheme should be able to realize the speed monitoring of multiple transmission shafts through one encoder, which can not only improve the utilization rate of the encoder, but also greatly reduce the risk of reduced work efficiency caused by encoder failure. However, most of the existing encoder mounting support designs fail to meet this demand, therefore, it is particularly urgent and necessary to develop a new type of encoder mounting support. SUMMARY

[0005] Therefore, the utility model provides an encoder mounting support, which can select a standby encoder to monitor the speed of the motor output shaft when the encoder loses monitoring effect.

[0006] To solve the above technical problems, the utility model provides an encoder mounting support, which comprises a fixed plate, a motor output shaft is fixed in the fixed plate through a bearing, a first transmission shaft is connected to the end of the motor output shaft, the motor output shaft can drive the first transmission shaft to rotate, a support frame is further arranged on the side edge of the fixed plate, a plurality of second transmission shafts are further arranged on the support frame through bearings, the plurality of second transmission shafts can rotate on the support frame, a transmission gear is arranged at the end of the first transmission shaft and the second transmission shaft, the plurality of transmission gears are consistent in structure, the transmission gear on the first transmission shaft and the transmission gear on each second transmission shaft are meshed with each other, the rotation speed of the plurality of transmission gears is 1:1, the plurality of transmission gears can make the second transmission shaft and the first transmission shaft rotate synchronously; the rotation speed of the second transmission shaft is consistent with that of the first transmission shaft.

[0007] The first transmission shaft or the second transmission shaft is connected with the encoder away from the one end of the motor output shaft, and the encoder is fixedly arranged on the support frame, and the rotation speed of the motor output shaft can be indirectly monitored through the encoder.

[0008] The support frame comprises a connecting ring arranged at the side edge of the fixed plate, the connecting ring is fixedly connected with the fixed plate, a plurality of connecting rods are fixedly arranged on the connecting ring and vertically arranged between the connecting ring and the connecting rod, the first support plate and the second support plate are fixedly arranged between the plurality of connecting rods, the first support plate and the second support plate are arranged in parallel, the second transmission shaft is arranged on the first support plate through a bearing, the second transmission shaft can rotate on the first support plate, the second support plate is used for supporting the encoder, and the encoder is fixedly arranged on the second support plate through bolts.

[0009] The second transmission shaft and / or the motor output shaft are fixed through double bearings, so that the position of the second transmission shaft or the motor output shaft is more stable.

[0010] The connecting rod is a screw rod, the screw rod is fixedly arranged on the connecting ring through thread cooperation, the screw rod can be detached from the connecting ring, a plurality of through holes are arranged on the first support plate and the second support plate corresponding to the screw rod, the through holes are arranged on the first support plate or the second support plate, the screw rod is connected with the first support plate or the second support plate through the through holes, the first support plate or the second support plate can slide on the screw rod through the through holes, and the first support plate or the second support plate is fixed through two nuts, so that the first support plate or the second support plate can be prevented from sliding on the screw rod through the two bolts.

[0011] The plurality of second transmission shafts are arranged in a ring shape with the first transmission shaft as the center.

[0012] The plurality of second transmission shafts are arranged in a linear array between the first transmission shaft.

[0013] Compared with the prior art, the present application has at least one of the following beneficial technical effects:

[0014] 1. Improve the utilization rate of the encoder and reduce the cost: through the encoder mounting support of the utility model, only one encoder can realize the rotation speed monitoring of multiple transmission shafts (including the second transmission shaft indirectly driven by the motor output shaft through the first transmission shaft). This design greatly improves the utilization rate of the encoder, avoids the resource waste of the traditional design that each transmission shaft needs to be equipped with an independent encoder. At the same time, since the number of encoders is reduced, the overall cost of the equipment and the subsequent maintenance cost are also reduced.

[0015] 2. Stable working efficiency: when one of the encoders is damaged, other encoders can be quickly replaced to monitor the rotation speed of the motor output shaft, without waiting for the disassembly and replacement of the encoder before working.

[0016] 3. Enhanced system reliability and stability: The support structure of the utility model through the precise gear transmission design, ensure the synchronous rotation between the first transmission shaft and multiple second transmission shafts. This synchronism not only improves the precision of the system, but also enhances the reliability and stability of the entire motion control system. Even when a certain transmission shaft corresponding encoder fails, since other transmission shafts can still be monitored through the shared encoder, thus can greatly reduce the risk of system downtime.

[0017] 4. Flexibility and scalability: The support frame part of the support adopts modular design, through the flexible combination of connecting ring and connecting rod (screw rod), the number and layout of the second transmission shaft can be easily adjusted. This design makes the encoder mounting support of the utility model can adapt to the demand of motor equipment of different scale and complexity, has good flexibility and scalability.

[0018] 5. Simplify maintenance and replacement process: Since the encoder is fixedly arranged on the support frame, and the connecting rod is provided as a screw rod for easy disassembly and installation, when the encoder needs to be maintained or replaced, the entire support does not need to be disassembled on a large scale. This design simplifies the maintenance process, reduces the operation difficulty and time cost.

[0019] 6. Optimize space layout and aesthetics: Multiple second transmission shafts can be arranged in a ring shape with the first transmission shaft as the center, or in a linear array between the first transmission shaft. Both of these two layout methods optimize the space utilization, making the entire support structure more compact and beautiful. At the same time, this orderly layout also helps to improve the overall reliability and stability of the equipment. BRIEF DESCRIPTION OF DRAWINGS
