Description
Technical Field
The utility model belongs to the technical field of mechanical equipment technique and specifically relates to indicate a bearing locking device that is used for cavity rotary platform speed reducer.
Background
The hollow rotating platform speed reducer acts between the motor and the working machine or the actuating mechanism to match rotating speed and transmit torque, is a very precise machine and is mainly used for reducing the rotating speed of the motor and increasing the torque of the motor. The middle hole in the middle of the speed reducer can be used for passing a wire through pipe.
Most of the devices for fixing the bearing are fixed by using snap springs, and the snap springs have too small bearing moment and are easy to deform. Or adopt the flange apron, press down the bearing through making the step on the flange apron, then fix the flange apron through the screw and reach fixed bearing, this kind adopts the flange apron to fix and to bear the weight of moment great, but the cooperation precision of pressing the bearing is guaranteed to the unable way.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention provides a bearing locking device for a hollow rotating platform speed reducer, which can lock a bearing accurately and fixedly.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a bearing locking device for a hollow rotary platform speed reducer comprises an output rotary platform, a bearing and a locking nut; the lower end of the output rotating platform is provided with external screw threads; the bearing sleeve is arranged at the lower end of the output rotating platform and is positioned above the outer thread; the inner side surface of the locking nut is provided with inner threads which are screwed with the outer threads, the inner side and the outer side of the locking nut penetrate through the inner threads to form a wire slot, the end surface of the locking nut is provided with a plurality of thread holes, and each thread hole penetrates through the wire slot and is screwed with a screw.
Preferably, the number of the line slots is two, and the two line slots are arc-shaped and are radially and symmetrically arranged.
Preferably, the plurality of thread holes are evenly distributed at intervals on the circumference.
Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme:
through set up the line slot on lock nut to the cooperation lock nut terminal surface is equipped with a plurality of thread holes, and effectively runs through the line slot, through the screw of adjusting the lock nut terminal surface, makes lock nut's thread take place to warp, makes lock nut be difficult for the pine to take off, thereby realizes accurate effective fixing bearing.

Detailed Description
Referring to fig. 1 and 2, a detailed structure of a preferred embodiment of the present invention is shown, which includes an output rotary table 10, a bearing 20 and a lock nut 30.
The lower end of the output rotary table 10 is provided with an external screw thread 11; the bearing 20 is sleeved on the lower end of the output rotary table 10 and is located above the outer thread 11.
An inner thread 31 is formed on an inner side surface of the locking nut 30, the inner thread 31 is in threaded connection with the outer thread 11, a thread slit 32 is formed through the inner side surface and the outer side surface of the locking nut 30, a plurality of thread holes 33 are formed on an end surface of the locking nut 30, and each thread hole 33 penetrates through the thread slit 32 and is in threaded connection with a screw 40. In this embodiment, the number of the thread cutting slits 32 is two, and the thread cutting slits are arc-shaped and radially and symmetrically arranged, and the plurality of thread holes 33 are equally arranged at intervals on the circumference.
Detailed description the working principle of the present embodiment is as follows:
during assembly, the bearing 20 is firstly sleeved on the lower end of the output rotary table 10, then the inner screw thread 31 is matched with the outer screw thread 11, so that the locking nut 30 is connected with the lower end of the output rotary table 10, the upper end surface of the locking nut 30 is abutted against the lower end surface of the bearing 20, and then the connecting screw 40 is screwed in each screw thread hole 33, so that the inner screw thread 31 of the locking nut 30 is deformed, the locking nut 30 is locked on the output rotary table 10 and cannot be easily loosened, and the locking of the bearing 20 is realized.
The utility model discloses a design key is: through set up the line slot on lock nut to the cooperation lock nut terminal surface is equipped with a plurality of thread holes, and effectively runs through the line slot, through the screw of adjusting the lock nut terminal surface, makes lock nut's thread take place to warp, makes lock nut be difficult for the pine to take off, thereby realizes accurate effective fixing bearing.
The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
