Abstract
Description
Technical field:
[0001] The utility model relates to the technical field of industrial automation equipment manufacturing, in particular to an output end reinforcing device for a reducer which can significantly improve the output end strength of a reducer and reduce the failure caused by the root fracture of the output shaft of the reducer. Background technology:
[0002] At present, in industrial automation equipment, reducers cooperate with power components such as motors to realize power conversion and transmission, and the output shaft of the reducer is connected to the load. However, the traditional reducer has weak radial load-bearing capacity and insufficient rigidity, which often leads to the radial force reaching the limit during application, but there is still a large redundancy in torque. In order to take into account the radial force requirements, only a larger reducer can be selected, which causes waste, and when used for vertical lifting, the root of the output shaft is prone to breakage, which is very likely to cause safety accidents. Summary of the invention:
[0003] In view of the shortcomings and deficiencies in the prior art, the utility model proposes an output end reinforcing device for a reducer which has a reasonable structure, is easy to assemble and can significantly improve the load-bearing capacity of the output end.
[0004] The utility model achieves this through the following measures:
[0005] An output end reinforcement device for a reducer is characterized in that a flange is provided at the output end of the reducer, a cylindrical roller bearing is built into the flange, and the output shaft of the reducer cooperates with the cylindrical roller bearing.
[0006] The flange of the utility model is provided with a strip-shaped hole, so as to cooperate with the gear clearance adjustment mechanism to adjust the meshing clearance between the gear and the rack.
[0007] The gear is connected to the end of the output shaft of the reducer in the utility model, and the gear is meshed with the rack on the truss. A gear clearance adjustment mechanism is provided on the side of the flange close to the gear. The gear clearance adjustment mechanism includes a supporting and fixing plate, a sliding groove is provided on the supporting and fixing plate, and the open end of the sliding groove is arranged on the side away from the rack. The width of the sliding groove is adapted to the flange, and a limiting plate is provided at the opening of the sliding groove. A bolt hole is provided on the limiting plate, and the limiting plate is connected to the supporting and fixing plate via fixing bolts. The flange is located in the sliding groove and is connected to the adjusting bolt on the side close to the opening of the sliding groove. The adjusting bolt is locked in from the outside along the bolt hole on the limiting plate. A locking bolt for locking the flange to the supporting and fixing plate via the strip hole is also provided on the flange.
[0008] When the utility model is in use, the locking bolt on the flange is loosened, and the adjusting bolt on the outer side of the limit plate is adjusted at this time to adjust the relative position of the flange and the sliding groove. Since the flange is connected to the output end of the reducer as a whole, the position of the flange can be adjusted to adjust the matching clearance between the gear at the output end of the reducer and the rack on the truss. After the adjustment is completed, the flange and the supporting fixing plate are fixed and locked by the locking bolt. After the reducer is running, since the flange is added to the output end of the reducer and the cylindrical roller bearing is built in, the radial load-bearing capacity can be improved, so that the torque and the radial force upper limit are matched.
[0009] Compared with the prior art, the utility model can reduce the size of the reducer and reduce the cost. When the reducer is running, the radial force is borne by the front end bearing and will not be transmitted to the root of the output shaft, which fundamentally solves the root fracture problem and improves the safety factor of the equipment. In addition, it is also compatible with the tooth gap adjustment function. Description of the drawings:
[0010] Attached Figure 1 It is a structural schematic diagram of the utility model.
[0011] Attached Figure 2 It is a schematic diagram of the installation of the reducer and the flange in the utility model.

[0013] Figure numerals: flange 1, cylindrical roller bearing 2, reducer output shaft 3, strip hole 4, gear 5, rack 6, support and fixing plate 7, limit plate 8, adjustment bolt 9, reducer 10. Specific implementation method:
[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0015] Example:
[0016] As attached Figure 1 As shown, this example provides an output end reinforcement device for a reducer, which is provided with a flange 1 located at the output end of the reducer, a cylindrical roller bearing 2 is built into the flange 1, and the output shaft 3 of the reducer cooperates with the cylindrical roller bearing 2;
[0017] As attached Figure 2 As shown, the flange 1 is provided with a strip hole 4 so as to cooperate with the gear clearance adjustment mechanism to adjust the meshing clearance between the gear and the rack.
[0018] In this example, the output shaft end of the reducer is connected to the gear 5, and the gear 5 is meshed with the rack 6 on the truss. A gear clearance adjustment mechanism is provided on the side of the flange 1 close to the gear. The gear clearance adjustment mechanism includes a supporting and fixing plate 7, a sliding groove is provided on the supporting and fixing plate 7, and the open end of the sliding groove is arranged on the side away from the rack 6. The width of the sliding groove is adapted to the flange 1. A limiting plate 8 is provided at the opening of the sliding groove, and a bolt hole is provided on the limiting plate 8. The limiting plate 8 is connected to the supporting and fixing plate 7 through fixing bolts. The flange 1 is located in the sliding groove, and is connected to an adjusting bolt 9 on the side close to the opening of the sliding groove. The adjusting bolt 9 is locked in from the outside along the bolt hole on the limiting plate. The flange 1 is also provided with a locking bolt for locking the flange 1 and the supporting and fixing plate 7 through a strip hole.
[0019] When in use, loosen the locking bolt on the flange 1, and then adjust the adjusting bolt 9 on the outside of the limit plate 8 to adjust the relative position of the flange 1 and the sliding groove. Since the flange 1 is connected to the output end of the reducer as a whole, the position of the flange 1 can be adjusted to adjust the clearance between the gear at the output end of the reducer and the rack on the truss. After the adjustment, the flange 1 and the supporting fixing plate 7 are fixed and locked by the locking bolt; after the reducer is running, since the flange 1 is added to the output end of the reducer and the cylindrical roller bearing 2 is built in, the radial load-bearing capacity can be improved to match the torque with the upper limit of the radial force.
[0020] Compared with the prior art, the utility model can reduce the size of the reducer and reduce the cost. When the reducer is running, the radial force is borne by the front end bearing and will not be transmitted to the root of the output shaft, which fundamentally solves the root fracture problem and improves the safety factor of the equipment. In addition, it is also compatible with the tooth gap adjustment function.
