Easily and efficiently dismounting is interference fitted in the bearing inner race on axis, and does not damage parts, bearing and transmission shaft, subtracts significantly
Low assembly and maintenance cost improve working efficiency.
The bevel gear shaft of the utility model, including transmission shaft, be shaped in the end part of driving shaft bevel gear and
Bearing removal component for pushing the outer bearing being sleeved on transmission shaft；The bearing removal component includes that sliding outer cover is being driven
Pressure ring on axis and push bracket for pushing pressure ring to slide axially is set on bevel gear；The push bracket includes being located at cone tooth
The push plate of outer end is taken turns, is axially fixed in the push rod of the push plate and is rotationally connected in push plate in a manner of axial limiting
Heart screw rod；The through-hole that the push rod is disposed through bevel gear peaks at the end face of pressure ring；The center bolt and it is set to cone tooth
Take turns the threaded hole cooperation of outer end face；
Further, the screw rod is screw, and the bar portion of the screw is equipped with the snap ring for being limited to push plate；
Further, the bevel gear inner face is formed with the annular groove for accommodating the pressure ring, and bevel gear outer end face is equipped with
Circular groove for accommodating the push plate；
Further, the push plate is circular configuration, and the push rod is distributed with multiple around push plate axis；
The utility model has the beneficial effects that：A kind of bevel gear shaft provided by the utility model, the bevel gear shaft can pass through
Bearing carries out rotating support, and bearing is usually resisted against the inner face of bevel gear, when needing to dismantle bearing, can with rotary screw,
The screw rod can be rotated relative to push bracket, while be axially fixed between push bracket, and screw rod rotation will drive push plate and push rod edge
Axial movement, and thrust is transferred to pressure ring by push rod, the diameter of pressure ring is roughly the same with bearing inner race, and the thrust of push bracket is logical
Pressure ring impeller-hub is crossed to hold along transmission shaft axial movement, to carry out the dismounting of bearing, the utility model utilizes pressure ring transmitting thrust,
Be conducive to uniformly apply axial thrust to bearing inner race, in addition, screw spiral transmission can generate larger axial thrust, keep away
Exempt to occur between bearing and transmission shaft stuck.Dismounting bearing inner race that can be easily and fast, and parts, bearing are not damaged
And transmission shaft, lower assembly and maintenance cost significantly, improves working efficiency.
Description of the drawings
The utility model is further described with reference to the accompanying drawings and examples：
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Fig. 1 is the structural schematic diagram of the utility model, as shown, the bevel gear shaft in the present embodiment, including transmission shaft
6, the bevel gear 1 of 6 end of the transmission shaft and the bearing 7 for pushing the outer bearing 7 being sleeved on transmission shaft 6 are shaped in
Dismantle component；It includes that pressure ring 8 and setting of the sliding outer cover on transmission shaft 6 are used on bevel gear 1 that the bearing 7, which dismantles component,
In the push bracket for pushing pressure ring 8 to slide axially；The push bracket includes the push plate 3 for being located at 1 outer end of bevel gear, is axially fixed in institute
It states the push rod 2 of push plate 3 and is rotationally connected with the center bolt of push plate 3 in a manner of axial limiting；The push rod 2 passes through setting
The end face of pressure ring 8 is peaked in the through-hole of bevel gear 1；The center bolt is matched with the threaded hole 5 for being set to 1 outer end face of bevel gear
It closes, which can carry out rotating support by bearing 7, and bearing 7 is usually resisted against the inner face of bevel gear 1, when needs are torn open
, can be with rotary screw when unloading bearing 7, which can rotate relative to push bracket, while is axially fixed between push bracket, screw rod
Rotation will drive push plate 3 and push rod 2 to be axially moveable, and thrust is transferred to pressure ring 8, the diameter and axis of pressure ring 8 by push rod 2
