Abstract
The utility model discloses an axis transmitting gear pressing device of a micro motor, which comprises a base, a bracket, a transmitting nut and a guiding chute. A positioning sleeve of the transmitting gear of the micro motor is arranged on the base, and the transmitting nut is arranged on a beam of the bracket. A roof used for fixing the micro motor is arranged at the end of the transmitting nut. Besides, driven by the transmitting nut, the micro motor can press a motor shaft of the micro motor accurately into an inner hole of the transmitting gear in the positioning sleeve of the transmitting gear of the micro motor on the base along the guiding chute arranged on a vertical board of the bracket, so that the assembly working procedure of the transmitting gear of the micro motor is completed.
Description
Technical field:
The utility model relates to a kind of miniature electrical machinery axle and is pressed into transmission gear means, belongs to machinery manufacturing technology field.
Background technology:
Transferring power is normally come by interference fit in the motor shaft of used micromachine and travelling gear hole on the circuit breaker electric motor structure.The rotating shaft of micromachine is very thin and long, and general diameter is 3mm, long 75mm, and draw ratio reaches 25, and travelling gear has certain magnitude of interference (the general magnitude of interference is 0.02-0.03) with axle when assembling.Traditional installation method is: adopt travelling gear is directly knocked in motor shaft, because the gear mesh spindle guide is to bad, be subjected to percussion power inhomogeneous on the circumference, after causing gear to be knocked in, motor shaft flexural deformation, rotor and stator are interfered mutually, and dragging armature is lived, some motor is energy usefulness reluctantly, does not also reach instructions for use in its result of use and service life.At present the another kind of assembly method of using is: adopt gear hot jacket method, after gear heat, be inserted in motor shaft in the fluid that boils, treat that gear cools off after, closely cooperate with motor shaft.This method is easy to cause gear place heat transferred motor, destroys the insulating properties of motor, also can make motor be infected with greasy dirt simultaneously.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model has provided a kind of micromachine shaft transmission gear press-in device.This travelling gear press-in device operation easily is pressed into accurately, has not only guaranteed the assembly quality of micromachine travelling gear effectively, and has improved the efficiency of assembling of micromachine travelling gear.
The technical scheme that the utility model adopted is:
Micromachine shaft transmission gear press-in device described in the utility model includes parts such as base, support, transmission nut, guide chute, on base, is provided with micromachine travelling gear positioning sleeve; Transmission nut is installed on the crossbeam of support, end at transmission nut, be provided with the top board that is used for fixing micromachine, micromachine is under the driving of transmission nut, along the guide chute that is arranged on the support riser, the motor shaft of micromachine can be pressed into like clockwork in the endoporus of the travelling gear in the micromachine travelling gear positioning sleeve that is located on the base, thereby finish the assembly process of micromachine travelling gear.

The specific embodiment:
Micromachine shaft transmission gear press-in device described in the utility model includes parts such as base 4, support 9, transmission nut 8, guide chute 11, and support 9 is made up of rack beam 1 and support riser 2; On base 4, be provided with micromachine travelling gear positioning sleeve 5; Transmission nut 8 is installed on the crossbeam 1 of support, in the end of transmission nut 8, is provided with the top board 7 that is used for fixing micromachine, and guide chute 11 is arranged on the support riser 2; In order to reduce to move up when transmission nut 8 rotates and support 9 generation end-face frictions, on transmission nut 8, bearing 10 is installed.
During assembling, elder generation packs travelling gear 3 in the travelling gear positioning sleeve 5, micromachine 6 is placed jacking block 7, rotation transmission nut 8, by its inner screw thread pair and the guide effect that is arranged at the guide chute 11 on the support riser 2, force jacking block 7 to move down, thereby micromachine 6 lower end spindle guides are gone in the gear hole, continue rotation transmission nut 8, can finish micromachine 6 and be connected with travelling gear 3 assemblings.
The utility model is rational in infrastructure, easy to use, and is simple to operate, applied widely.Change the top board 7 on base 4 upper transfer gear positioning sleeves 5 and transmission nut 8 ends, promptly applicable to the assembling of micromachine and its travelling gear of various different size models.
