Description

Easy-dismount bevel gear shaft

Technical field

The utility model is related to field of gears, and in particular to a kind of easy-dismount 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 easy-dismount 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 easy-dismount 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 easy-dismount 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 along coaxially setting The centre bore being placed on the bevel gear outer end face, the sliding block being snug fit in the centre bore, be set to transmission shaft outer circle, And the bar-shaped trough of the connection centre bore, and be connected to the sliding block and stretch out the gear outside transmission shaft across the bar-shaped trough Piece；

Further, the catch has multiple along sliding block is circumferentially distributed, and the bar-shaped trough and catch have been arranged in a one-to-one correspondence more It is a；

Further, the bevel gear inner face is formed with the annular groove for accommodating the catch；

Further, the sliding block outer circle is equipped with the card slot for being clamped the catch；The catch is sector structure.

The utility model has the beneficial effects that：A kind of easy-dismount 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 utilize One pole be inserted into centre bore tap sliding block, sliding block drive catch slide axially together, catch push bearing along transmission shafts to Mobile, to carry out the dismounting of bearing, the utility model utilizes catch transmitting thrust, is conducive to uniformly apply to bearing inner race Axial thrust avoids occurring between bearing and transmission shaft stuck.Dismounting bearing inner race that can be easily and fast, and do not damage Parts, bearing and transmission shaft lower assembly and maintenance cost significantly, improve 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；

Fig. 2 is the distribution schematic diagram of the catch of the utility model.

Specific implementation mode

Fig. 1 is the structural schematic diagram of the utility model, as shown, 7 axis of detachable bevel gear in the present embodiment, including Transmission shaft 5, the bevel gear 7 for being shaped in 5 end of the transmission shaft and for pushing the outer bearing 6 being sleeved on transmission shaft 5 Bearing 6 dismantle component；It includes that edge is coaxially disposed in the centre bore on 7 outer end face of the bevel gear that the bearing 6, which dismantles component, 1, the sliding block 2 being snug fit in the centre bore 1 is set to 5 outer circle of transmission shaft and is connected to the bar-shaped trough of the centre bore 1 4, and be connected to the sliding block 2 and stretch out the catch 3 outside transmission shaft 5 across the bar-shaped trough 4；7 axis of bevel gear can pass through Bearing 6 carries out rotating support, and bearing 6 is usually resisted against the inner face of bevel gear 7, when needing to dismantle bearing 6, can utilize one Pole is inserted into centre bore 1 and taps sliding block 2, and sliding block 2 drives catch 3 to slide axially together, and catch 3 pushes bearing 6 along transmission shaft 5 Axial movement, to carry out the dismounting of bearing 6, the utility model utilizes 3 transmitting thrust of catch, is conducive to uniformly to bearing 6 Inner ring applies axial thrust, avoids occurring between bearing 6 and transmission shaft 5 stuck.6 inner ring of dismounting bearing that can be easily and fast, And parts, bearing 6 and transmission shaft 5 are not damaged, lowers assembly and maintenance cost significantly, improves working efficiency.

In the present embodiment, the catch 3 has multiple along sliding block 2 is circumferentially distributed, and the bar-shaped trough 4 and catch 3 correspond It is provided with multiple；Multiple catch 3 act on 6 end face of bearing simultaneously, make 6 uniform force of bearing.

In the present embodiment, 7 inner face of the bevel gear is formed with the annular groove for accommodating the catch 3；Bearing 6 is installed When, catch 3 can be fully accommodated in annular groove, avoid the axial dimension for increasing gear shaft.

In the present embodiment, 2 outer circle of the sliding block is equipped with the card slot for being clamped the catch 3；The catch 3 is sector Structure, the contact area when catch 3 of sector structure can increase dismounting bearing 6 with 6 end face of bearing.

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.
