Technical field

The utility model is related to field of gears, and in particular to a kind of detachable bevel gear shaft.

Background technology

Bevel gear shaft is widely used in machine industry, such as in automobile manufacturing field, and rear axle is that vehicle power passes The component part for the rear drive shaft passed generally is made of two half-bridges, and is provided with the differential that differential mechanism realizes left and right trailing wheel Movement；And in the transmission mechanism of power, it is passed using smaller bevel gear shaft and the larger driven bull wheel for being fixed on differential mechanism Dynamic cooperation, realizes the transmission of power；In the prior art, bevel gear is integrally formed to form bevel gear shaft with transmission shaft, and is being driven The axle journal of axis goes out to be arranged useful bearing, and carrying transmission shaft rotation avoids frictional resistance, ensures transmission efficiency；And due to bearing inner race It is interference fit, the end face of bearing inner race and the end face gap very little of drive bevel gear with transmission shaft, is easily damaged in detachable Bearing inner race and part, to cause, bearing and gear are scrapped and disassembly process is time-consuming and laborious.

Therefore, in order to solve the above problem, a kind of detachable bevel gear shaft is needed, interference can be easily and efficiently dismantled and match The bearing inner race being combined on the shaft, and parts, bearing and transmission shaft are not damaged, lower assembly and maintenance cost significantly, improves Working efficiency.

Utility model content

In view of this, the purpose of the utility model is to overcome defect in the prior art, a kind of detachable bevel gear is provided Axis can easily and efficiently dismantle the bearing inner race being interference fitted on axis, and not damage parts, bearing and transmission shaft, Lower assembly and maintenance cost significantly, improves working efficiency.

The detachable bevel gear shaft of the utility model, including transmission shaft, the cone tooth for being shaped in the end part of driving shaft It takes turns and for pushing the bearing removal component for being sleeved on the bearing on transmission shaft outside；The bearing removal component includes sliding outer cover Pressure ring on transmission shaft and push bracket for pushing pressure ring to slide axially is set on bevel gear；The push bracket includes position In bevel gear outer end push plate and be fixed on the push rod of the push plate；The through-hole that the push rod is disposed through bevel gear peaks at The end face of pressure ring；

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；

Further, the bevel gear outer end face is formed with pilot hole along axis, and the push bracket further includes coaxially being fixed on to push away Plate, and the guide post being slidably matched with pilot hole.

The utility model has the beneficial effects that：A kind of detachable bevel gear shaft provided by the utility model, the bevel gear shaft Rotating support can be carried out by bearing, bearing is usually resisted against the inner face of bevel gear, when needing to dismantle bearing, can tap The push plate of push bracket, thrust are transferred to pressure ring by push rod, and the diameter of pressure ring is roughly the same with bearing inner race, and the thrust of push bracket passes through Pressure ring pushes bearing to be moved axially along transmission shaft, and to carry out the dismounting of bearing, the utility model utilizes pressure ring transmitting thrust, has Conducive to uniformly axial thrust is applied to bearing inner race, avoid occurring between bearing and transmission shaft stuck.Can be easily and fast Bearing inner race is dismantled, and does not damage parts, bearing and transmission shaft, lowers assembly and maintenance cost significantly, improves work effect Rate.

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 detachable bevel gear shaft in the present embodiment, including Transmission shaft 6, the bevel gear 1 for being shaped in 6 end of the transmission shaft and for pushing the outer bearing 7 being sleeved on transmission shaft 6 Bearing 7 dismantle component；It includes that pressure ring 8 and setting of the sliding outer cover on transmission shaft 6 are boring tooth that the bearing 7, which dismantles component, For pushing the push bracket that pressure ring 8 slides axially on wheel 1；The push bracket includes being located at the push plate 3 of 1 outer end of bevel gear and fixing In the push rod 2 of the push plate 3；The push rod 2, which passes axially through, to be set to the through-hole of bevel gear 1 and peaks at the end face of pressure ring 8；The cone Gear shaft can carry out rotating support by bearing 7, and bearing 7 usually be resisted against the inner face of bevel gear 1, when needing to dismantle bearing 7 When, the push plate 3 of push bracket can be tapped, thrust is transferred to pressure ring 8, diameter and 7 inner ring of the bearing substantially phase of pressure ring 8 by push rod 2 Together, the thrust of push bracket pushes bearing 7 to be moved axially along transmission shaft 6 by pressure ring 8, and to carry out the dismounting of bearing 7, this practicality is new Type utilizes 8 transmitting thrust of pressure ring, is conducive to uniformly apply axial thrust to 7 inner ring of bearing, avoid bearing 7 and transmission shaft 6 it Between occur it is stuck.7 inner ring of dismounting bearing that can be easily and fast, and parts, bearing 7 and transmission shaft 6 are not damaged, significantly Lower assembly and maintenance cost, improves working efficiency.

In the present embodiment, 1 inner face of the bevel gear is formed with the annular groove for accommodating the pressure ring 8,1 outer end of bevel gear Face is equipped with the circular groove for accommodating the push plate 3；When installing bearing 7, pressure ring 8 can be fully accommodated in annular groove, avoid increasing The axial dimension of shaft gear, and the stroke that push plate 3 is moved when circular groove can increase dismounting.

In the present embodiment, the push plate 3 be circular configuration, the push rod 2 be distributed with around 3 axis of push plate it is multiple, it is multiple to push away Bar 2 is resisted against 8 end face of pressure ring simultaneously, makes 8 uniform force of pressure ring.

In the present embodiment, 1 outer end face of the bevel gear is formed with pilot hole 5 along axis, and the push bracket further includes coaxial solid Due to push plate 3, and the guide post 4 being slidably matched with pilot hole 5, pilot hole 5 can ensure with being slidably matched for guide post 4 in bearing 7 When dismounting, entire push bracket is moved axially along transmission shaft 6.

Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the right of the utility model.
