For realizing above-mentioned purpose; The dismounting frock of the utility model motor bearings; It comprises bearing clamping plate, tie-plate, jack, jack upper frame and drag hook, and the bearing clamping plate are spliced to form by two semicircular annulus, and annulus is set on the motor shaft between rotor and motor bearings; The axial cross section of tie-plate is the ring set of I shape, and tie-plate is set in motor shaft one end, and its two ends are respectively dish and ring set lower wall on the ring set, and tray bottom is butted on motor bearings under the ring set, and is fixedly connected with the bearing clamping plate; The jack bottom places on the motor shaft, and the jack upper frame is provided with the holddown groove of three above drag hooks, and drag hook one end is fixed in the drag hook holddown groove of jack upper frame, and the other end is provided with and colludes groove, and dish snaps in colluding in the groove of the drag hook other end on the ring set of tie-plate.
Said bearing clamping plate are provided with the bolt hole more than three, and the bolt hole of the corresponding bearing clamping plate of the ring set lower wall of tie-plate is provided with bolt hole, by the ring set lower wall of bolt bearing clamping plate and tie-plate.
The said motor shaft other end is provided with is convenient to the upright cover of the vertical rotor of placing of motor shaft, and the upright cover of rotor bottom is provided with base, and the surface extends upward sleeve, and the motor shaft other end is inserted in the sleeve.
Be provided with the jack cushion cover between said jack bottom and motor shaft one end.
Adopt the dismounting frock of the motor bearings of the utility model, between the ring set lower wall of bearing clamping plate and tie-plate, jack transmits pulling force through jack upper frame, drag hook, tie-plate, and motor bearings is removed from motor shaft with the motor bearings holding.This dismounting tool structure is simple, and cost is low, can repeatedly repeat practicality; Simultaneously, adopt the dismounting frock of the utility model, the motor bearings disassembling section is convenient, and time saving and energy saving, the motor bearings after the dismounting can also be recycled.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the dismounting frock of the utility model motor bearings;
Fig. 2 is the structural representation of the utility model jack upper frame.
Embodiment
Like Fig. 1 or shown in Figure 2; The dismounting frock of the utility model motor bearings; It comprises bearing clamping plate 1, tie-plate 2, jack 3, jack upper frame 4 and drag hook 5, and bearing clamping plate 1 are spliced to form by two semicircular annulus, and annulus is set on the motor shaft 8 of 7 of rotor 6 and motor bearingss; The axial cross section of tie-plate 2 is the ring set of I shape, and tie-plate 2 is set in motor shaft 8 one ends, and its two ends are respectively equipped with dish 21 and ring set lower wall 22 on the ring set, and ring set lower wall 22 bottoms are butted on motor bearings 7, and are fixedly connected with bearing clamping plate 1; Jack 3 bottoms place on the motor shaft 8; Jack upper frame 4 is provided with the holddown groove 41 of three above drag hooks 5; Drag hook 5 one ends are fixed in the drag hook holddown groove 41 of jack upper frame, and the other end is provided with and colludes groove 51, and dish 21 snaps in colluding in the groove 51 of the drag hook other end on the ring set of tie-plate 2.
Adopt above structure; Bearing clamping plate 1 are snapped in 7 of rotor 6 and motor bearingss; The ring set lower wall 22 and the bearing clamping plate 1 of tie-plate are fixed as one; Thereby motor bearings 7 is located at 22 of the ring set lower walls of bearing clamping plate 1 and tie-plate,, can power be delivered on the bearing clamping plate 1 through tie-plate 2 is carried out the application of force.
When dismantling motor bearings 7; Earlier bearing clamping plate 1 are set on the motor shaft 8 of 7 of rotor 6 and motor bearingss; Again ring set lower wall of tie-plate 22 and bearing clamping plate 1 are fixed as one, then jack 3 are placed on the motor shaft 8, the bottom that cylinder 31 jack-up of jack 3 are inserted in jack upper frame 4; Make colluding on the ring set that groove 51 snaps in tie-plate of the drag hook that is fixed on the jack upper frame 4 coil 21, thereby dish 21 is connected as a single entity on the ring set of drag hook 5 and tie-plate.Continue to drive the cylinder 31 of jack; Jack upper frame 4 pulling drag hooks 5 up move; Coil 21 on the ring set of drag hook 5 drive tie-plates; And then the ring set lower wall 22 of tie-plate 2 drives motor bearings 7 and bearing clamping plate 1 together up move, and motor bearings 7 is pulled out motor shaft 8 the most at last, realizes the dismounting of motor bearings 7 and motor shaft 8.
