Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, an input structure 10 of a motor and a reducer includes: a motor 11 and a reducer 12. The input structure 10 of the motor and the speed reducer further includes: a driving synchronizing wheel 13, a synchronous belt 14 and a driven synchronizing wheel 15. The driving synchronizing wheel 13 is fixed to the motor 11 shaft of the motor 11. The driven synchronizing wheel 15 is fixed to an input shaft 121 of the speed reducer 12. The synchronous belt 14 is sleeved on the peripheries of the driving synchronous wheel 13 and the driven synchronous wheel 15. The rotational axis of the motor 11 shaft of the motor 11 is parallel to the rotational axis of the input shaft 121 of the reducer 12.
Specifically, the input structure 10 of the motor and the speed reducer enables the rotation axis of the shaft of the motor 11 to be parallel to the rotation axis of the input shaft 121 of the speed reducer 12 through the transmission structure of the driving synchronizing wheel 13, the synchronous belt 14 and the driven synchronizing wheel 15, so that the motor 11 and the speed reducer 12 are corner-mounted without changing the form of the speed reducer 12, the mounting space is saved, and the requirement of specific mounting space can be met. Meanwhile, after the installation position or direction of the motor 11 is changed, the connection mode of the motor 11 and the speed reducer 12 is kept unchanged, shaft input can be realized, the speed reducer 12 does not need to be replaced, and the cost is reduced.
As a specific implementation manner, the input structure 10 of the motor and speed reducer further includes: bearing support 16 and reduction housing 20. The motor 11 is mounted to a bearing block 16. One end of the speed reducer 12 is fixed to the bearing housing 16 and the other end is fixed to the speed reducer housing 20. With such a mounting structure, the rotational axis of the motor 11 shaft of the motor 11 can be set parallel to the rotational axis of the input shaft 121 of the speed reducer 12, and corner mounting of the motor 11 and the speed reducer 12 can be realized without changing the form of the speed reducer 12.
Further, the bearing housing 16 is formed with a first through hole 161 and a second through hole 162. The first through hole 161 is for passing through one end of the motor 11 having the shaft of the motor 11. The second through hole 162 is for the input shaft 121 of the speed reducer 12 to pass through. The motor 11 and the reducer 12 are mounted to the same side of the bearing housing 16. The reduction housing 20 is formed with a third through-hole 201. The third through hole 201 is for the output shaft 122 of the speed reducer 12 to pass through.
Further, two bearings 17 are provided in the second through hole 162. The two bearings 17 are sleeved on the outer periphery of the input shaft 121. The outer surface of the input shaft 121 is formed with a stopper projection 1211. The two bearings 17 are respectively located at both sides of the restriction projection 1211, and sandwich the restriction projection 1211 from both sides of the restriction projection 1211, so that the axial position and the radial position of the input shaft 121 can be defined.
Still further, the bearing housing 16 is provided with a bearing cover 18. The bearing cap 18 is fixed to the bearing housing 16 by screws 19. The bearing cover 18 and the bearing block 16 are now located on either side of the two bearings 17. At this time, the two bearings 17 are integrated, and the bearing cover 18 and the bearing housing 16 clamp the two bearings 17 from both sides of the two bearings 17, so that the positions of the two bearings 17 can be defined to prevent the two bearings 17 from being displaced. This can further prevent the input shaft 121 from being displaced in the axial direction, ensuring structural stability.
In a specific embodiment, the bearing housing 16 is formed with a first mating surface 163. The first mating surface 163 is for mating with the outer race of one of the two bearings 17 to define that bearing 17. The bearing cap 18 is formed with a second mating face 181. The second mating surface 181 is for mating with the outer race of the other of the two bearings 17 to define the bearing 17. Specifically, the first mating face 163 and the second mating face 181 contact the sides of the two bearings 17 that are away from each other, respectively. This defines the axial as well as the radial position of the two bearings 17.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
