Description

Technical Field

[0001] The present application relates to the field of motor technology, and in particular to a one-piece reduction motor. Background Art

[0002] In the prior art, a motor refers to an electromagnetic device that realizes electrical energy conversion or transmission according to the law of electromagnetic induction. Since the motor has a high rotation speed, common drive components cannot directly receive the high rotation speed from the motor. Therefore, an external reducer is usually required to perform a reduction operation. However, the reducer also needs to be connected to the motor with the help of a coupling, which results in more connection structures between the motor and the drive components, which will not only increase the energy loss of the system, but also increase the probability of maintenance. Therefore, how to achieve reduction operation and simplify the transmission structure is particularly important for the reduction transmission. Utility Model Content

[0003] The problem to be solved by the present application is that when the existing motor is driven, it needs to be equipped with a reducer due to its high speed. However, a coupling is also required between the motor and the reducer for transmission, which makes the transmission structure of the motor too complicated, which not only increases the energy loss of the system, but also increases the probability of maintenance.

[0004] In order to solve the above-mentioned technical problems, the present application provides a one-piece reduction motor, including a body for providing driving force, and a shell arranged at the output end of the body. The interior of the shell is provided with a reduction component which is directly connected to the body to simplify the transmission structure, improve the transmission efficiency and reduce the maintenance rate.

[0005] Since the reduction motor of the present application is designed with a reduction component, the transmission structure can be effectively simplified through a direct connection with the body, thereby improving the transmission efficiency and reducing the maintenance rate. This solves the problem that the motor in the prior art needs to be equipped with a reducer due to its high speed when driving, and a coupling is also required between the motor and the reducer for transmission, which makes the transmission structure of the motor too complicated, which not only increases the energy loss of the system, but also increases the probability of maintenance.

[0014] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0015] The present application relates to a one-piece reduction motor, such as Figure 1-7 As shown, the reduction motor includes a body 2 for providing driving force, an output end of the body 2 is arranged with a shell connected thereto, a reduction member directly connected to the body 2 is arranged inside the shell, thereby effectively simplifying the output transmission structure of the motor with the aid of the directly connected reduction member, and an output shaft for connecting to the reduction member to realize transmission operation is arranged at the output end of the body 2.

[0016] In order to facilitate the loading and unloading operations of the speed reducer, the shell and the body 2 can be connected by detachable bolts.

[0017] The reduction gear includes a worm 6 and a worm wheel 5. The worm 6 is coaxially arranged with the output shaft, and the worm wheel 5 is arranged in the vertical direction of the worm 6 and meshingly connected with it. In order to realize the supporting operation of the worm 6 and the worm wheel 5, bearing seats for connecting with the housing are symmetrically arranged at both ends of the worm 6 and the worm wheel 5.

[0018] In order to replace the coupling and simplify the connection structure between the output shaft and the worm 6, a plug-in mortise and tenon structure is adopted between the output shaft and the worm 6. The end of the output shaft has a tenon 8 protruding outward, and the end of the worm 6 has a mortise 10 recessed inward and matched with the tenon 8. In order to improve the connection strength of the tenon 8 and the mortise 10, the cross-sectional shape of the tenon 8 and the mortise 10 is a straight groove structure, thereby avoiding slippage between the output shaft and the worm 6.

[0019] In order to further enhance the firmness of the connection between the output shaft and the worm 6, a through hole 9 penetrating the output shaft and the worm 6 is formed in the vertical direction of the tenon 8 and the mortise 10, and a pluggable stopper 7 is arranged inside the through hole 9. The stopper 7 can be a bolt, a nut or other structures that also have a stopper operation.

[0020] In order to facilitate the inspection, maintenance and loading and unloading operations of the speed reducer, the shell is a split-type detachable connection structure, which is divided into a movable shell 4 and a fixed shell 1 according to different layout forms. The fixed shell 1 is detachably connected to the motor by bolts, and the movable shell 4 is detachably connected to the fixed shell 1 by bolts. Therefore, when the speed reducer needs to be repaired and maintained, it is only necessary to remove the movable shell 4.

[0021] A connector 3 for power connection is arranged below the movable shell 4 .

[0022] When in use, the worm wheel 5, the worm 6 and the fixed shell 1 are pre-assembled, and then the fixed shell 1 and the motor are assembled so that the tenon 8 of the output shaft can be smoothly inserted into the mortise 10 of the worm 6, and then the limiter 7 is used for additional fixing operations. Then the movable shell 4 and the fixed shell 1 can be installed. In this way, the assembly operation of the reduction motor is completed. Compared with the transmission structure of the reducer with an additional coupling for connection, the reduction motor effectively optimizes the transmission structure of the motor and reduces the transmission loss caused by the overly complicated transmission structure. The reduction motor with tight connection and less structure also reduces the failure rate.

[0023] It is to be understood that the present application is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present application. In addition, under the guidance of the present application, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present application. Therefore, the present application is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are within the scope protected by the present application.
