Abstract
Title of the present utility model is that a kind of bearing promotes device, is related to a kind of promotion device for being used to dismantle electric car gearbox axle upper bearing (metal).The problem of it is mainly solved when being changed after bearing inner race or outer ring damage, and current method is to tap bearing with hammer or copper rod to be dismantled, and causes bending shaft or gear failure to scrap, and operating efficiency is low and labor intensity is big.It is to promote to be set with adapter sleeve on set in the bearing being made up of two semicylinders that bearing of the present utility model, which promotes device, bearing promotes an inner circle end of set to be provided with boss, it is cubic type hole that bearing, which promotes the centre bore of the other end of set, outer sides nut is installed, push rod is threadedly attached in outer sides nut in the cubic type hole.The utility model is reasonable in design, easy to use, and maintenance replacing bearing speed is fast, had both solved the problems, such as that the axle of gearbox two was pounded deformation when changing bearing or gear is smashed, and had alleviated labor intensity again, improve operating efficiency.
Description
Technical field
It the utility model is related to a kind of bearing and promote device, be particularly used for dismantling electric car gearbox axle upper bearing (metal)
Promotion device.
Background technology
In electric car gearbox, because bearing inner race and the axle of gearbox two coordinate tighter, bearing face and two axle teeth
It is small to take turns end clearance（2mm）Furthermore the shaft diameter of gearbox two is thinner（21 mm）, changed after bearing inner race or outer ring damage
When, current method is to tap bearing with hammer or copper rod to be dismantled, and often results in two bending shafts or gear failure is scrapped, work
Efficiency is low and labor intensity is big.
The content of the invention
The purpose of this utility model be in view of the shortcomings of the prior art, and propose it is a kind of reasonable in design, replacing axle
Hold that speed is fast and not damaged, percent defective is low, easy to use, and effect is good, can reduce labor intensity, and improves the bearing of operating efficiency
Promote device.
Technical solution of the present utility model is：Bearing, which promotes device, is promoted in the bearing being made up of two semicylinders
Put and be set with adapter sleeve, bearing promotes an inner circle end of set to be provided with boss, and bearing promotes the center of the other end of set
Hole is cubic type hole, is provided with outer sides nut in the cubic type hole, push rod is threadedly attached in outer sides nut.
Bearing described in technical solution of the present utility model promotes the diameter of bore for being arranged with boss one end with treating
The external diameter of dismounting bearing matches, and the cubic type hole interior edge four directions type hole of the bearing promotion set other end is radially provided with groove, axle
Hold promote set be by cubic type hole it is diagonal centered on by bearing promote set dimidiation.
Outer sides nut section described in technical solution of the present utility model is T-shaped, and outer sides nut passes through the T
Shape is installed on bearing and promoted in the groove covered in cubic type hole.
One end of push rod described in technical solution of the present utility model be provided with it is top, the end of the other end is six sides
Shape, the top one end of push rod are located at bearing and promoted in set.
The utility model promotes set to be buckled on the bearing outer ring of damage when in use, by bearing, and adapter sleeve is enclosed on into bearing
Promotion is put, and is made bearing promote device to be fixed together with the bearing outer ring damaged, is recycled threaded push rod by the axle of damage
Hold extraction；The beneficial effects of the utility model are：Bearing promotion device is reasonable in design, and easy to use, effect is good, and maintenance is more
It is fast to change bearing speed, had both solved the problems, such as that the axle of gearbox two was pounded deformation when changing bearing or gear is smashed, and had mitigated again
Labor intensity, improves operating efficiency.

Embodiment
As shown in Fig. 1,2,3,4,5, it is by two semicylinders that bearing of the present utility model, which promotes the bearing of device to promote set 1,
Combine, promoted in bearing and adapter sleeve 2 is installed on set 1, inner circle and the bearing of adapter sleeve 2 promote the cylindrical of set 1 closely to match somebody with somebody
Close, the bearing of two semicylinder compositions promotes an inner circle end of set 1 to be provided with a boss, and bearing promotes 1 end of set
The external diameter of the diameter of endoporus and bearing 5 to be removed matches, and bearing promotes the size of circular diameter in set 1 than the chi of bearing 5 to be removed
Very little big 0.10mm；Bearing promotes the end of 1 other end of set to be fixed with outer sides nut 3, and the centre bore at 1 end of bearing promotion set is
Cubic type hole, bearing promote set 1 be by cubic type hole it is diagonal centered on by bearing promote set 1 dimidiation, in the cubic type hole
Interior edge four directions type hole is radially provided with groove, and the T-shaped outer sides nut 3 in section is installed on bearing and promotes 1 end square of set
In groove in hole；Outer sides nut 3 carries internal thread, and push rod 4 is threadedly attached in outer sides nut 3；The one of push rod 4
End is provided with top, and the end of the other end be hexagon, and push rod 4, which is provided with top one end and is located at bearing promotion, to be covered in 1, and push rod 4 is set
There is hexagonal one end to be used for back-up wrench.
Operation principle：In use, first by bearing of the present utility model promote the bearing of device promote set 1 one of those half
Cylinder spiral-lock bearing 5 to be removed it is cylindrical on, then by tapped outer sides nut 3 be put into the bearing promote set 1 half
In the groove of round cylinder, bearing is then promoted 1 another semicylinder spiral-lock of set in the cylindrical and cubic of bearing 5 to be removed
On nut 3, finally adapter sleeve 2 be sleeved on bearing promote set 1 it is cylindrical on be fixed as one, be screwed into threaded push rod 4, push up
Top one end of bar 4 is withstood in the centre bore of two shaft ends, and turn push rod 4 exits bearing 5 to be removed from two axles, replaces with
New bearing.
