Technical field
The utility model relates to the bearing extractor that uses in the mechanical assembling process, and concrete is the bearing extractor that is applicable in the endoporus.
Background technology
In lathe assembling or machinery assembling, usually run into the problem of bearing dismantling.Bearing for being installed on the axle can be with drawing horse (being commonly called as pawl) to get off bearing removal when dismantling.But bearing and casing for being installed in the casing endoporus have the shaft shoulder, bearing centre to have this situation of spacer difficult in the process of dismounting, and this situation is as shown in Figure 1.Difficult when dismantling bearing for this structure shown in Figure 1, because the no strong point and space can't be with drawing horse; Because the limited space pincers worker can't down be shaved with thin iron prop.The iron prop even have living space down also can damage bearing accuracy, destructible retainer and raceway.
Summary of the invention
The purpose of the utility model provides a kind of provision for disengagement of casing endoporus middle (center) bearing, and this device can not cause any infringement to tearing open bearing in unloading process, installs simple to operately, and function is practical.
Be to realize the foregoing invention purpose, the technical problem that the application adopts is: boring bracing strut bearing extractor, comprise try to stop people from fighting each other, lock sleeve, positioning sleeve, axle, support, thrust ball bearing, fixed cover, nut and handle; Said trying to stop people from fighting each other comprises the fixedly pull bar of pulling claw of an end, and the other end of pull bar is set to helicitic texture; The main body of said lock sleeve is a ring-type, along the circumference uniform distribution screwed hole of lock sleeve, connects the adjustment screw rod on the screwed hole, and the nut top of adjustment screw rod is provided with circular trough, and lock sleeve is enclosed within on the pull bar; The main body of said positioning sleeve is circular; Circle wall along positioning sleeve is uniformly distributed with circular hole; And the screw hole that communicates with these circular holes is set on the horizontal end face of positioning sleeve, and in each circular hole of positioning sleeve, inserting axle, axle puts through the screw stationary positioned; The axle that inserts continues to be inserted in the nut top circular hole of adjustment screw rod, and the other end is stuck on the outer race end face to be removed; The horizontal end face of positioning sleeve is provided with four grooves, and each pawl of pulling claw is embedded in respectively in the groove of positioning sleeve end face; The main body of said support comprises a perpendicular end surface and is symmetrical in two horizontal struts of this end face; The center of perpendicular end surface is processed with circular hole; Support penetrates in the pull bar through circular hole; On perpendicular end surface, be that the center also is evenly equipped with screw hole with the circular hole, the stepped bolt holes of level of processing direction in the two Horizontal Branch cylinders, support is fixed on the tank wall through bolt hole; Said fixed cover comprises an edge portion, on the edge, is processed with screw hole, and fixed cover is connected with bracket screw, and the perpendicular end surface center of fixed cover is provided with circular hole, installed thrust ball bearing between fixed cover and the support; Said nut set inside level and perpendicular screwed hole, the nut horizontal direction pull bar that is threaded, the vertical direction handle that is threaded, the perpendicular end surface of nut contacts with the end face of thrust ball bearing.
The beneficial effect of the utility model: after this bearing extractor adopts said structure; Be stuck on the outer race end face behind 4 adjustment screw rods through this device and 4 axle stretchings; Through rotary handle the pulling claw of the pull bar other end is applied active force then; Thereby, drive bearing and walk toward outside, pull down the bearing in the casing.This extracting tool is simple to operate, and shaft strength is even, has the function of protection bearing and other each part precision, and again because this provision for disengagement adopts is combining structure, individual construction is simple, it is relatively easy to make, and uses adjustment also very convenient.

The specific embodiment
Below in conjunction with accompanying drawing the application is further described:
Combine shown in Figure 2 by Fig. 1: boring bracing strut bearing extractor, comprise try to stop people from fighting each other 1, lock sleeve 2, positioning sleeve 3, axle 4, support 5, thrust ball bearing 6, fixed cover 7, nut 8 and handle 9.
Combined shown in Figure 5 by Fig. 4: said trying to stop people from fighting each other 1 is made up of pulling claw 11, pulling claw fixed cover 12 and pull bar 13; One end of pull bar 13 be inserted in the centre bore of annular pulling claw fixed cover 12 and welding fixing; Four equally distributed pulling claws 11 of welding on the outer circle wall of pulling claw fixed cover 12, the other end of pull bar 13 is set to helicitic texture.
Combined shown in Figure 6 by Fig. 2: the main body of said lock sleeve 2 is a ring-type, along four screwed holes of circumference uniform distribution of lock sleeve 2, connects adjustment screw rod 10 on the screwed hole, and the nut top of adjustment screw rod 10 is provided with circular trough; Lock sleeve 2 is enclosed within on the pull bar 13.
Combine Fig. 7, shown in Figure 8 by Fig. 2: the main body of said positioning sleeve 3 is circular; Circle wall along positioning sleeve 3 is uniformly distributed with four circular holes 31; And the screw hole 32 that communicates with circular hole 31 is set on the horizontal end face of positioning sleeve 3, and in each circular hole 31 of positioning sleeve 3, inserting axle 4, axle 4 is through on the screw stationary positioned cover 3; The axle 4 that inserts continues to be inserted in the nut top circular hole of adjustment screw rod 10, and the other end is stuck on the outer race end face to be removed; On the horizontal end face of positioning sleeve 3, with four screw hole 32 equidistance be staggeredly equipped with four grooves 33, the width of the width of groove 33 and pulling claw 11 is corresponding; To pull bar 13 centre distances, each pulling claw 11 is embedded in respectively in the groove 33 of positioning sleeve 3 end faces the internal diameter of positioning sleeve 3 less than pulling claw 11 free ends.
