Abstract
The utility model discloses a kind of loading machine Drive axle housing components, it includes support shaft and axle housing；The support shaft is equipped with support shaft step, threaded hole and support shaft endoporus；The axle housing is equipped with axle housing step, bolt hole and axle shell shaft-head；Support shaft endoporus is mounted on by hot jacket on axle shell shaft-head, and support shaft end face is adjacent to axle housing step surface, and is passed through washer, bolt, bolt hole and threaded hole and locked support shaft and axle housing.The loading machine Drive axle housing component has the characteristics that simple and compact for structure, easy to maintenance and at low cost, service life of equipment is long, and solving the problems, such as axle housing, the excessive easy cracking of weld seam even fracture, the component failure rate on matrix for leading to low axle housing bearing capacity, axle housing and support shaft of the axle housing two supports axis concentricity caused by welding is high with support shaft.
Description
Technical field
The utility model is related to loading machines to drive bridge device, particularly a kind of loading machine Drive axle housing component.
Background technology
Loading machine Drive axle housing component is the matrix for installing main reducing gear, semiaxis, hub reduction gear, brake, is made
With being to support and protect main reducing gear, semiaxis etc..At present, in loading machine industry, axle housing component is generally using axle housing and bearing
The structure that axis is welded due to being influenced easily to be deformed by many factors in welding process, leads to axle housing both ends branch
The concentricity for holding axis is excessive, so as to be substantially reduced the bearing capacity of axle housing, also increases the event of the parts on matrix
Barrier, causing axle housing and the weld seam of support shaft, easily cracking is even broken, and leverages the safety of loading machine.
Invention content
The purpose of the utility model is to overcome drawbacks described above, provide it is a kind of it is simple and compact for structure, easy to maintenance and at low cost,
The loading machine Drive axle housing component of service life of equipment length, solves axle housing and support shaft axle housing two supports axis caused by welding
The excessive weld seam for leading to low axle housing bearing capacity, axle housing and support shaft of concentricity easily cracks or even is broken, on matrix
Component failure rate it is high the problem of.
In order to achieve the above object, a kind of loading machine Drive axle housing component of the utility model, it includes support shaft and axle housing；
The support shaft is equipped with support shaft step, threaded hole and support shaft endoporus；The axle housing be equipped with axle housing step, bolt hole and
Axle shell shaft-head；Support shaft endoporus is mounted on by hot jacket on axle shell shaft-head, and support shaft end face is adjacent to axle housing step surface, and is passed through
Washer, bolt, bolt hole and threaded hole lock support shaft and axle housing.
Preferably, the fit system of support shaft endoporus and axle shell shaft-head is interference fit.
Preferably, the clamping screw diameter of support shaft and axle housing is more than 14mm, and quantity is no less than 8.
A kind of above-mentioned loading machine drive axle unit construction bridge shell component is by using the assembled knot between support shaft and axle housing
Structure has following technical characterstic and advantageous effect：
1st, for support shaft by support shaft endoporus hot jacket in axle shell shaft-head, fit system passes through bolt to be interference fitted
Locked, this addresses the problem axle housing two supports axis concentricity caused by welding it is excessive cause axle housing bearing capacity drop
The problem of component failure rate height and axle housing and the weld seam of support shaft low, on matrix easily crack or even are broken, guarantor
The safety of loading machine has been demonstrate,proved, has improved product quality.
2nd, when support shaft is worn, support shaft can be carried out individually more using fabricated construction between support shaft and axle housing
It changes, thus substantially increases the maintainability of axle housing component, reduce three guarantees expense.
3rd, cancel welding manner, reduce the discharge of enterprise's welding exhaust gas, improve the feature of environmental protection of enterprise.
Description of the drawings
Fig. 1 is a kind of loading machine Drive axle housing component main cross section structure diagram of the utility model.
Fig. 2 is the main cross section structure diagram of support shaft in Fig. 1.
Fig. 3 is Fig. 1 intermediate axle shell structure diagrams.
Reference numeral：Support shaft 1, support shaft step 11, threaded hole 12, support shaft endoporus 13, washer 2, bolt 3, axle housing
4th, axle housing step 41, bolt hole 42, axle shell shaft-head 43.
Specific embodiment
To the utility model, a kind of loading machine Drive axle housing component is made further in the following with reference to the drawings and specific embodiments
It is described in detail.
A kind of loading machine Drive axle housing component of the utility model shown in Fig. 1~Fig. 3 includes support shaft 1 and axle housing 4；It is described
Support shaft 1 is equipped with support shaft step 11, threaded hole 12 and support shaft endoporus 13, and the axle housing 4 is equipped with axle housing step 41, spiral shell
Keyhole 42 and axle shell shaft-head 43；The support shaft endoporus 13 by hot jacket be mounted on axle shell shaft-head 43 on, support shaft endoporus 13 with
Matching for axle shell shaft-head 43 is combined into interference fit type；1 end face of support shaft is adjacent to 4 step surface of axle housing, by washer 2, bolt 3,
Bolt hole 42 and threaded hole 12 lock support shaft 1 and axle housing 4；Support shaft 1 and the clamping screw diameter of axle housing 4 are more than 16mm,
And quantity is no less than 8.
During assembling, support shaft endoporus 13 is first heated to 90~100 DEG C, axle shell shaft-head 43 is then aligned with and is packed into, make bearing
1 end face of axis is adjacent to 4 step surface of axle housing, is locked support shaft 1 and axle housing 4 by washer 2, bolt 3, bolt hole 42, threaded hole 12
Tightly.Solve caused by axle housing 4 and support shaft 1 are welded that axle housing 4 two supports axis, 1 concentricity is excessive to cause axle housing 1 to carry in this way
Ability reduction, the failure of parts increased on matrix, the easy cracking of weld seam of axle housing 4 and support shaft 1 even break
The problem of splitting ensure that the safety of loading machine, improve product quality.
The support shaft 1 and axle housing 4 of above-mentioned loading machine Drive axle housing component are by using fabricated construction, when support shaft 1
During abrasion, support shaft 1 can be individually replaced, thus substantially increase the maintainability of axle housing component, reduced three and cover all expenses
With；In addition, the cancellation of welding manner, reduces the discharge of enterprise's welding exhaust gas, the feature of environmental protection of enterprise is improved.
