A kind of bearing device for taking, including seat, intermediate plate and ejection screw rod are pushed, described promotion seat one end inlay card is in bearing
On roll shaft between roller, the other end connects the intermediate plate, and the ejection screw rod is threadedly coupled and one with the intermediate plate
End abuts roll shaft；The ejection screw rod is vertically and fixedly provided with bull stick far from one end of the roll shaft；The promotion seat include bottom plate and
Two are vertically fixed on the support rod of bottom plate two sides, and two support rods pass through intermediate plate and end is equipped with limited cap；The bottom plate
On offer U-type groove compatible with roll shaft, bottom plate is mounted on the roll shaft between bearing and roller by the way that U-type groove is chimeric.
Through the above technical solutions, pushing roller of the seat one end by the U-type groove inlay card on bottom plate between bearing and roller
On axis, make to push the assembly and disassembly of seat simple and convenient, it is time saving and energy saving；Promotion seat other end connection intermediate plate, and spiral shell on intermediate plate
Line connects an ejection screw rod abutted with roll shaft, then by the bull stick of rotation ejection screw rod end, and by passing through intermediate plate
Two support rods help manpower hold holding rod keep intermediate plate it is motionless, prevent ejection screw rod rotation when drive intermediate plate together
Rotation, causes to be difficult to the problem of taking out bearing；Due to the threaded function between ejection screw rod and intermediate plate, screw rod roll shaft is ejected
There is the squeezing action power of a direction roller, and pedestal is also by the reaction force backwards to roller, the mating reaction of the two power,
Make to eject screw rod slowly by roll shaft from pedestal ejection, also makes pedestal gradually mobile to the direction far from roller with bearing, finally
Bearing is dismantled, disassembly bearing conveniently technical effect is reached.
Further preferably are as follows: the intermediate position of the bull stick is fixed with the holding ring of frame shape.
It is rotated through the above technical solutions, holding ring and can be convenient manpower and hold bull stick, effectively reduces manpower and turning
It skids on bar, the situation of rotation bull stick inconvenience occurs.
Further preferably are as follows: the holding ring is covered equipped with soft holding.
Through the above technical solutions, soft hold the frictional resistance that covers and can increase when manpower holds holding ring, further
The generation of slippery conditions is reduced, and soft set of holding can also protect the palm of people, mitigate and even palm is avoided to hold holding
Feeling of pain when ring.
Further preferably are as follows: the side of the intermediate plate is fixedly connected with holding rod.
Through the above technical solutions, the side of intermediate plate is fixedly connected with holding rod, manpower is facilitated to hold in holding rod holding
Between plate it is motionless, while rotating bull stick, facilitate operation.
Further preferably are as follows: the holding rod is covered equipped with soft holding.
Through the above technical solutions, soft holding set can reduce a possibility that skidding when manpower holds holding rod, from
And can stablize and keep intermediate plate motionless, rotation ejection screw rod realizes disassembly bearing.
Further preferably are as follows: one end that the support rod is fixedly connected with the bottom plate be equipped with screw thread, the support rod with
Bottom plate is connected through a screw thread fixation.
Through the above technical solutions, being threadedly coupled between support rod and bottom plate, then detachable between support rod and bottom plate, side
Just change the bottom plate with different size U-type groove according to the size of roll shaft, bearing can be removed from various sizes of roll shaft, it is general
Property is more preferable.
In conclusion the utility model has the following beneficial effects:
1. chimeric bottom plate on the roll shaft between bearing and roller, by one end setting intermediate plate in promotion seat, and
It is threadedly coupled on intermediate plate and ejects screw rod, rotation ejection screw rod simultaneously keeps intermediate plate fixed, due to ejection screw rod and centre
Threaded function between plate, ejection screw rod roll shaft has the squeezing action power of a direction roller, and pedestal is also by backwards to roller
The reaction force of cylinder, the mating reaction of the two power make to eject screw rod slowly by roll shaft from pedestal ejection, also make pedestal gradually band
Bearing it is mobile to the direction far from roller, to conveniently and efficiently dismantle bearing；
2. being respectively provided with soft holding set on the holding ring and holding rod for needing manpower to help, both manpower was facilitated to exert a force, it can also
To reduce generated feeling of pain when manpower is held.
