Abstract
The utility model discloses a box bearing puller, relating to a screw assembly composed of a screw and a flange; wherein, a handle is arranged in the inner hole at one end of the screw and perpendicular thereto; the flange is provided with a through hole sharing the identical bolt hole number and position with the box bearing end cover; plugs capable of circumferential rotation corresponding to the screw are arranged at the other end of the screw. The diameter of a plug is less than that of the outer housing of the disassembly bearing and is relative to the diameter of the bearing inner casing or a little bigger; the diameter of the other plug is relative to the diameter of the outer casing of the disassembly bearing and is a little smaller than the bearing hole. The utility model can be used for gently pressing out bearings from the box hole without any damage to the box. The utility model has the advantages of simple structure, compact design, convenient and fast operation, which is thus suitable for fieldwork/hands-on operation and is capable of meet the purpose of disassembly.
Description
Technical field:
The utility model relates to a kind of casing shaft bearing replacer, is used to dismantle the bearing in the casing dead eye.
Background technology:
In repair procedures, when if desired bearing being disassembled, use the mode of hammering often from the casing dead eye.This method is brought inconvenience and some accidents to the maintenance personal.Be in particular in: (1) repair work wastes time and energy; When (2) knocking dismounting, easily damage casing, cause unnecessary economic loss.
Summary of the invention:
The purpose of this utility model provides a kind of casing shaft bearing replacer, utilizes it bearing can be extruded from box body hole gently, time saving and energy saving, operation facility, safe and reliable.
The purpose of this utility model realizes as follows: this casing shaft bearing replacer relates to the lead screw pair of being made up of leading screw and flange, in an end endoporus of leading screw, the handle vertical with leading screw is housed, the through hole that adapts with casing bearing (ball) cover number of bolt hole and position is arranged on the flange, and the other end of leading screw is equipped with can be relative to the top that leading screw circumferentially rotates.When dismounting during bearing, with bolt with flange tightly in casing bearing (ball) cover place, rotational lead screw withstands bearing inner race or bearing outside makes it break away from casing and the purpose that reaches dismounting.
The diameter of top is decided according to the inner ring and the overcoat diameter of institute's dismounting bearing.By roof pressure bearing inner race dismounting bearing the time, the top diameter is less than the overcoat of institute's dismounting bearing, adapts with the bearing inner sleeve diameter or bigger; By roof pressure bearing outside dismounting bearing the time, the overcoat of the diameter of top and institute's dismounting bearing adapts and is slightly less than dead eye.
The advantage that this casing shaft bearing replacer has is: simple in structure, volume is small and exquisite; Easy to operate, quick, do not damage casing.Be suitable for execute-in-place, can reach the purpose of dismounting box body hole middle (center) bearing well.
Description of drawings:
Fig. 1 is the schematic diagram of a kind of structure of the utility model casing shaft bearing replacer.
Fig. 2 is the schematic diagram of the another kind of structure of the utility model casing shaft bearing replacer.
The specific embodiment:
With reference to Fig. 1, Fig. 2, form lead screw pair by leading screw 4 and flange 3, in an end endoporus of leading screw 4, the handle vertical with leading screw 1 is housed, handle 1 also can slide along the hole, and handle 1 two ends are equipped with and are held ball 2, and the handled easily person grips.The through hole that adapts with casing bearing (ball) cover number of bolt hole and position is arranged on the flange 3, and this through hole can be circular hole, also can be ellipse or strip hole.The other end of leading screw is equipped with can be relative to the top 5 that leading screw circumferentially rotates.In Fig. 1, top 5 diameter is less than the overcoat of institute's dismounting bearing, adapts with the bearing inner sleeve diameter or bigger; In Fig. 2, the diameter of top 5 and the overcoat of institute's dismounting bearing adapt and are slightly less than dead eye.
In conjunction with Fig. 1, Fig. 2, use at dismounting K18DG vehicle deceleration case worm bearing overcoat further describes to this casing shaft bearing replacer: before the dismounting worm bearing, earlier the two ends end cap is disassembled, use stripping attachment among Fig. 1, use bolted in casing lower end end caps flange, make top 5 withstand worm shaft and bearing inner sleeve, turn handle 1 clockwise, rotational lead screw 4, drive top 5 reaches, by the worm screw pillow block, upper end bearing outside and the worm shaft that is in the casing opposite side can be disassembled safely; Next use the stripping attachment of Fig. 2, penetrate casing, make top 5 withstand other end bearing outside, flange is fastened on casing upper end end caps, tighten leading screw 4 then with bolt, ditto described, the bottom end bearing overcoat is disassembled safely.
Claims (3)
1, a kind of casing shaft bearing replacer, relate to the lead screw pair of forming by leading screw and flange, in an end endoporus of leading screw, the handle vertical with leading screw is housed, it is characterized in that: having the through hole that adapts with casing bearing (ball) cover number of bolt hole and position, the other end of leading screw (4) to be equipped with on the flange (3) can be relative to the top (5) that leading screw (4) circumferentially rotates.
2, casing shaft bearing replacer according to claim 1 is characterized in that: the diameter of top (5) is less than the overcoat of institute's dismounting bearing, adapts with the bearing inner sleeve diameter or bigger.
3, casing shaft bearing replacer according to claim 1 is characterized in that: the diameter of top (5) and the overcoat of institute's dismounting bearing adapt and are slightly less than dead eye.
