Description
Technical field
The utility model relates to a kind of automobile parts more particularly to a kind of easy-dismount Novel wheel-side retarders.
Background technique
Hub reduction gear is afterbody deceleration torsion increasing device in automotive transmission, can be met using hub reduction gear total
Transmission ratio under the same conditions, reduces the load of the components such as speed changer, transmission shaft, main reducing gear, differential mechanism, semiaxis, size
The advantages that becoming smaller and drive axle is made to obtain the biggish road clearance, it is widely used in load truck, motorbus, cross-country
It in automobile and some other large-scale work mine car, but is found in the actual use of hub reduction gear, in hub reduction gear
Bearing between line shaft and shell is needed to be maintained after a protracted use, be replaced, but axis in the prior art
It holds and line shaft is not easy to disassemble in disassembly, make troubles to maintenance, the replacement in later period.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, adapt to reality and need, and provide a kind of structure design
Easy-dismount Novel wheel-side retarder novel, easy to removal and installation.
In order to realize that the purpose of this utility model, technical solution used by the utility model be：
A kind of easy-dismount Novel wheel-side retarder, including shell are designed, it further includes running through that shell is made of left housing and right shell
Through-hole on right shell and the line shaft being connect with the gear set in shell；The inner wall of the medial end of the through-hole is equipped with annular
Step, the ring-shaped step are equipped with flexible cushion rubber, and the line shaft in through-hole is equipped with bearing, the inner sidewall of the bearing
It is pressed on the flexible cushion rubber, flexible gum cover is equipped between bearing and through-hole side wall, the flexibility gum cover is covered in the axis
It holds, further includes annular pressing plate, the annular pressing plate insertion is installed in the outboard end of through-hole and is pressed in the lateral wall of bearing
On, and the internal diameter of the annular pressing plate is less than the diameter of bearing inner race, the edge of the annular pressing plate lateral wall extends outwardly simultaneously
It is pressed on the right shell outer wall of through-hole side, and the outwardly extending extension in annular pressing plate edge is connected by fixing bolt and right shell
It connects.
It preferably, further include the seal rubber sleeve covered on the line shaft, the annular pressing plate is covered in the seal rubber sleeve
On, and the annular fixed edge being pressed on annular pressing plate lateral wall is equipped at the edge of seal rubber sleeve, the annular fixed edge passes through
Screw is connect with the annular pressing plate.
The beneficial effects of the utility model are：
Its novel in structural design of the design is easy to maintenance closer to bearing, replacement, oiling in use, meanwhile, the design adopts
With the design of seal rubber sleeve, in use, the pressure after line shaft generation radial deflection to bearing can pass through this seal rubber sleeve
It is buffered, meanwhile, it allows bearing to shift radially by this seal rubber sleeve, avoids bearing directly and on right shell
The phenomenon that through-hole wall directly contacts firmly extends the service life of bearing.
Detailed description of the invention
Fig. 1 is the profile status structural schematic diagram of the utility model；
Fig. 2 is by enclosing part enlarged structure schematic diagram in Fig. 1.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples：
Embodiment 1：A kind of easy-dismount Novel wheel-side retarder, referring to Fig. 1, Fig. 2.
Including shell, shell is made of left housing 2 and right shell 1, further include the through-hole on the right shell 1 and with the tooth in shell
The line shaft 3 of wheel group connection（The above are the prior arts）.
The inner wall of the medial end of the through-hole in the design is equipped with ring-shaped step 5, and the ring-shaped step 5 is equipped with
Flexible cushion rubber 6, the line shaft in through-hole are equipped with bearing 4, and the inner sidewall of the bearing 4 is pressed on the flexible cushion rubber 6,
Meanwhile flexible gum cover 7 is equipped between bearing 4 and through-hole side wall, 7 sets of the gum cover of flexibility passes through this on the bearing 4
Seal rubber sleeve allows bearing to shift radially, and bearing is avoided directly directly to contact firmly with the through-hole wall on right shell
Phenomenon occurs, and extends the service life of bearing.
Further, it further includes annular pressing plate 9, and the insertion of annular pressing plate 9 is installed in the outboard end of through-hole simultaneously
It is pressed on the lateral wall of bearing, and the internal diameter of the annular pressing plate 9 is less than the diameter of 4 inner ring of bearing（The inner end of annular pressing plate 9
Portion is pressed on the inner ring of bearing 4）, meanwhile, the edge of 9 lateral wall of annular pressing plate extends outwardly and is pressed in the right side of through-hole side
On 1 outer wall of shell, and the outwardly extending extension 10 in annular pressing plate edge is connect by fixing bolt 11 with right shell 1.
Further, it further includes the seal rubber sleeve 12 covered on the line shaft 1, and 9 sets of the annular pressing plate is described
On seal rubber sleeve 12, and the annular fixed edge 13 being pressed on annular pressing plate lateral wall, the ring are equipped at the edge of seal rubber sleeve
Shape fixed edge 13 is connect by screw 14 with the annular pressing plate 9, while in this way by seal rubber sleeve to bearing seal, may be used also
Line shaft is avoided to contact when radial direction occurs mobile with the hard of annular pressing plate（It is buffered by seal rubber sleeve）.
To sum up, its novel in structural design of the design is easy to maintenance closer to bearing, replacement, oiling in use, meanwhile, this
Design uses the design of seal rubber sleeve, and in use, the pressure after line shaft generation radial deflection to bearing can be close by this
Sealing packs into row buffering, meanwhile, by this seal rubber sleeve allow bearing shift radially, avoid bearing directly with the right side
The phenomenon that through-hole wall on shell directly contacts firmly extends the service life of bearing.
What the embodiments of the present invention were announced is preferred embodiment, and however, it is not limited to this, the common skill of this field
Art personnel understand the spirit of the utility model easily according to above-described embodiment, and make different amplification and variation, but as long as
The spirit of the utility model is not departed from, it is all within the protection scope of the present utility model.
