Abstract
The utility model provides an external rotor motor bearing disassembling device, which is mainly composed of a force bearing platform, two or more pulling arms swung and flexibly connected around the force bearing platform and a puller composed of a thimble which is vertically installed at the center of the force bearing platform through threads. The external rotor motor bearing disassembling device is characterized in that a head component and a sleeve component are added, wherein, a wiring path is vertically arranged at the center of the sleeve component, the head component is sleeved on the sleeve component, a wiring path is also arranged at the lower end thereof, a wiring hole communicated with the wiring path is arranged on the side wall, and the head component is vertically propped against the bottom part of the thimble. When being used, the sleeve component is sleeved on the axle head of the external rotor type motor, the power supply wire is penetrated from the wiring hole through the wiring path, and the pulling arms are clamped at the bottom part of the motor bearing, therefore, the motor bearing can be disassembled by rotating the thimble.
Description
Technical field
The utility model provides a kind of external rotor electric machine bearing disassembling device, belongs to the dismounting field of mechanical technique.
Background technology
External-rotor-type ceiling fan commonly used and axial flow blower are being carried out machinery check and repair when changing bearing, need take off down bearing and check replacing, because be external-rotor motor, its power line is to draw from an end spindle nose, if bearing is taken off thimble that following time draws horse must be withstood spindle nose and could take off down bearing, thimble is certain to power line is damaged like that, so can't use the special-purpose horse of drawing, can only have two people to cooperate with hammer knocks bearing get off, this method is not only time-consuming but also require great effort, sometimes need several hrs bearing could be pulled down, and can make the crooked or damage of armature spindle when knocking with hammer, efficient is very low.
The utility model content
The purpose of this utility model provides a kind of external rotor electric machine bearing disassembling device that can overcome above-mentioned defective, easy to use, high efficiency.Its technical scheme is:
Comprise by force-bearing table, swing and be actively socketed on the horse of drawing that thimble that the torque arm more than two or two around the force-bearing table and screw thread be vertically mounted on the force-bearing table center forms, it is characterized in that: set up head part and external member, wherein the central longitudinal of external member is to being provided with away drawing lines, head part is sleeved on the external member, its lower end also is provided with away drawing lines, its sidewall is provided with and walks the cable hole that drawing lines is communicated with, and the thimble bottom vertical withstands on the head part.
The utility model compared with prior art, when taking off the external rotor electric machine bearing, torque arm is stuck in the bottom of motor bearings, and external member is sleeved on the spindle nose of external rotor electric machine, and the power line of motor is passed from cable hole through walking drawing lines, rotate thimble then, just can under the situation of not hindering power line, fast bearing be taken off down, and can not damage spindle nose, time saving and energy saving, improved operating efficiency greatly, excellent working performance.
Description of drawings
Fig. 1 is the utility model embodiment structural representation in use.
Among the figure: 1, force-bearing table 2, torque arm 3, thimble 4, head part 5, external member 6, walk drawing lines 7, cable hole 8, spindle nose 9, motor 10, bearing 11, power line
The specific embodiment
Among the embodiment shown in Figure 1, two torque arm 2 symmetry swings are actively socketed on the edge of force-bearing table 1, thimble 3 screw threads are vertically mounted on the center of force-bearing table 1, its bottom vertical withstands on the head part 4, head part 4 is sleeved on the external member 5, the central longitudinal of external member 5 is to being provided with away drawing lines 6, and the lower end of corresponding head part 4 with it also is provided with away drawing lines 6, and its sidewall is provided with and walks the cable hole 7 that drawing lines 6 is communicated with.
During work, torque arm 2 is stuck in the bottom of the bearing 10 of external rotor electric machine 9, external member 5 is sleeved on the spindle nose 8, the power line 11 of motor 9 is passed from cable hole 7 through walking drawing lines 6, rotate thimble 3 then, just can under the situation of not hindering power line 11, fast bearing 10 be taken off down, and can not damage spindle nose 8.
