Description

Technical Field

[0001] This utility model belongs to the technical field of torque limiters, and in particular relates to a high vibration-absorbing torque limiter. Background Technology

[0002] Torque limiters are widely used in the field of mechanical transmission. Power is transmitted from the motor to the reducer, and a torque limiter is added between the two. When the torque instantaneously exceeds the load of the equipment, the torque limiter disengages in time, that is, the driving and driven ends separate. Under normal conditions, they are in an engaged state. In the instant of overload, the steel ball slides out of the groove, and the residual torque is completely zero. It will not automatically reset, and even if it continues to run for a long time, it will be idling. It is suitable for high-speed applications and effectively avoids damage to components such as motors and reducers. During use, the limiter compensates for radial and angular deviations between the two shafts through a coupling. At the same time, the load types are diverse, and the load types exhibit pulse jumping characteristics. Among these torque pulses, most of the pulse torque is large and the duration is short. Usually, a coupling is added to one side of the limiter to reduce the frequent disengagement of the torque limiter due to such frequent torque pulse jumping during equipment operation.

[0003] Existing devices lack effective damping and vibration absorption capabilities, making it difficult to filter torque pulses. A large number of instantaneous pulse torques may cause the clutch to frequently overload and disengage.

[0004] Therefore, it is necessary to provide a new high-absorption torque limiter to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a high-vibration-absorbing torque limiter that adds a high-vibration-absorbing pin module to the torque transmission system. Through its damping effect, the torque pulse of the load is filtered, and most of the instantaneous pulse torque that may cause frequent disengagement is shielded, thereby greatly reducing the overload disengagement rate of the clutch.

[0006] To solve the above-mentioned technical problems, the high vibration absorption torque limiter provided by this utility model includes: a motor shaft, on which a limiter active end is sleeved, and a limiter passive end is rotatably mounted on the limiter active end. Multiple limiting steel balls are provided on one side of the limiter active end, and multiple locking grooves are provided on one side of the limiter passive end. The multiple locking grooves are respectively adapted to the multiple limiting steel balls. Multiple through holes are respectively opened on the outer wall of the limiter active end, and multiple hexagonal set bolts are respectively installed in the multiple through holes. The limiter active end is fixedly connected to the motor shaft through the multiple hexagonal set bolts.

[0007] A reducer shaft is provided on one side of the motor shaft, and a bushing is fitted on the upper part of the reducer shaft. The outer wall of the bushing is provided with two through holes, and multiple hexagon socket head cap screws are provided in the multiple through holes. The bushing is fixedly connected to the reducer shaft by the multiple hexagon socket head cap screws. Multiple custom bolts are fitted with multiple high-vibration-absorbing elastic blocks.

[0008] As a further embodiment of this utility model, the bushing is provided with a plurality of mounting through holes, and a plurality of custom bolts are provided in the plurality of mounting through holes, and a plurality of washers are fitted on the plurality of custom bolts.

[0010] As a further embodiment of this utility model, multiple uniform gaps are provided between the multiple high-vibration-absorbing elastic blocks and the inner walls of the multiple mounting through holes.

[0011] Compared with related technologies, the high vibration absorption torque limiter provided by this utility model has the following beneficial effects: In the torque transmission system, a high-vibration-absorbing pin module is added, and a damping rubber elastomer is installed. The gap between the pin module and the component hole compensates for the radial and angular deviations of the two shafts during installation. This elastomer also has strong damping and vibration-absorbing functions. Through its damping effect, it filters the torque pulses of the load, shielding most of the instantaneous pulse torques that may cause frequent disengagement, thereby significantly reducing the overload disengagement rate of the clutch. Moreover, the device is characterized by simple structure, convenient installation, wear resistance, high temperature resistance, low noise during use, low wear, long service life, and easy maintenance.

The high vibration absorption torque limiter includes: a motor shaft 1, on which a limiter active end 2 is sleeved, and a limiter passive end 3 is rotatably mounted on the limiter active end 2. Multiple limiting steel balls 4 are provided on one side of the limiter active end 2, and multiple locking grooves 5 are provided on one side of the limiter passive end 3. The multiple locking grooves 5 are respectively adapted to the multiple limiting steel balls 4. Multiple through holes 6 are respectively opened on the outer wall of the limiter active end 2, and multiple hexagonal set bolts 7 are respectively provided in the multiple through holes 6. The limiter active end 2 is fixedly connected to the motor shaft 1 through the multiple hexagonal set bolts 7. A reducer shaft 8 is provided on one side of the motor shaft 1. A bushing 9 is fitted on the upper part of the reducer shaft 8. Through holes 10 are respectively opened on the outer wall of the bushing 9. Multiple hexagonal set bolts 11 are respectively provided in the multiple through holes 10. The bushing 9 is fixedly connected to the reducer shaft 8 by the multiple hexagonal set bolts 11. The bushing 9 is provided with multiple mounting through holes, and multiple custom bolts 12 are provided in the multiple mounting through holes. Multiple washers 13 are fitted on the multiple custom bolts 12. The passive end 3 of the limiter has multiple threaded holes 14 on one side, and the multiple threaded holes 14 are adapted to multiple custom bolts 12 respectively. The bushing 9 is fixedly connected to the passive end 3 of the limiter through the multiple custom bolts 12. Multiple high-vibration-absorbing elastic blocks 15 are respectively fitted onto multiple custom bolts 12; Multiple uniform gaps are provided between the multiple high-vibration-absorbing elastic blocks 15 and the inner walls of the multiple mounting through holes.

[0016] In the torque transmission system, a high-vibration-absorbing pin module is added, and a damping rubber elastomer is installed. The gap between the pin module and the component hole compensates for the radial and angular deviations of the two shafts during installation. This elastomer also has strong damping and vibration-absorbing functions. Through its damping effect, it filters the torque pulses of the load, shielding most of the instantaneous pulse torques that may cause frequent disengagement, thereby significantly reducing the overload disengagement rate of the clutch. Moreover, the device is characterized by simple structure, convenient installation, wear resistance, high temperature resistance, low noise during use, low wear, long service life, and easy maintenance.

[0017] The working principle of the high vibration absorption torque limiter provided by this utility model is as follows: The first step: Power is output from the motor shaft 1 and first transmitted to the limiter active end 2, which is fixed to the motor shaft 1 by the internal hexagon set bolt 7; then, through the meshing structure of the limiter active end 2 and the limiter passive end 3's limiting steel ball 4 and locking groove 5, the power is transmitted to the limiter passive end 3; then, through the pin module composed of the custom bolt 12, high vibration-absorbing elastic block 15, and washer 13, the power is transmitted to the bushing 9, which is fixed to the reducer shaft 8 by the internal hexagon set bolt 11, and finally transmitted from the bushing 9 to the reducer shaft 8, completing the entire power transmission; The second step: Under normal operating conditions, the limiting steel ball 4 of the limiter's active end 2 is engaged in the locking groove 5 of the limiter's passive end 3, maintaining a meshed state to transmit torque. When the system torque instantaneously exceeds the equipment load, the overload torque will force the limiting steel ball 4 to slide out of the locking groove 5, causing the limiter's active end 2 to separate from the limiter's passive end 3. At this time, the limiter's active end 2 will idle, power transmission will be interrupted, and the residual torque will drop to 0, preventing damage to core components such as the motor and reducer due to overload. After separation, it will not automatically reset and requires manual intervention to restore meshing. The third step: The high-vibration-absorbing elastic block 15 (made of rubber elastomer) in the pin module has strong damping and vibration absorption performance. It can filter the pulse torque generated by the load through damping, shielding most of the instantaneous pulse torque that easily causes the limiter to frequently disengage, and significantly reducing the overload disengagement rate. At the same time, the uniform gap between the high-vibration-absorbing elastic block 15 and the inner wall of the mounting through hole can effectively compensate for the radial and angular deviations of the motor shaft 1 and the reducer shaft 8 during installation, reducing vibration and impact during equipment operation; and the conical surface of the custom bolt 12 and the conical hole (taper 1:10) at the front of the threaded hole 14 of the limiter passive end 3 can achieve self-locking and anti-loosening, ensuring stable torque transmission under heavy load and high vibration conditions, further improving the vibration absorption and buffering effect, and reducing operating noise and component wear.
