Abstract
The utility model discloses a kind of main reducer in drive axle for construction machines housing apparatus, it includes bracket, left adjusting nut, left bearing lid, left bearing, bolt, right bearing lid, right adjusting nut, right bearing；The casting of both the bracket and left bearing lid is integrated, and the right bearing cover bolt is fixed on bracket；Differential assembly is mounted on by left bearing and right bearing on the bearing hole at bracket both ends；It is locked respectively with left adjusting nut and right adjusting nut at the both ends of bracket.The Structural Engineering Mechanical Driven bridge main reducing gear housing apparatus has the characteristics that simple and compact for structure, efficiency of assembling and precision height, processing cost are low, after solving each assembling parts to final drive casing of driving bridge main reducing speed assembly in the prior art, because precision can not reach the problem of requirement leads to bearing earlier period damage.
Description
Technical field
The utility model is related to retarder equipment, particularly a kind of main reducer in drive axle for construction machines housing apparatus.
Background technology
Engineering machinery is widely used in all trades and professions, and main engineering machinery has loading machine, road roller, fork truck, excavation
The quality of the drive axle of one of machine etc., kernel component is even more important, and main gearbox assembly is the key that drive axle zero
Component, product quality are directly related to the whole performance of engineering machinery；Final drive casing is poor in main gearbox assembly
Fast device, bearing, bearing cap and adjusting nut matrix.Existing final drive casing generally using split structure, mainly by bracket,
The parts such as adjusting nut, bearing cap, bolt form.Critical component of the final drive casing as main gearbox assembly, due to each zero
Part causes overall precision to be unable to reach requirement, causes bearing concentricity poor there are mismachining tolerance after more assembling parts, occurs
Bearing earlier period damage.
Invention content
It is low with precision height, processing cost that the purpose of this utility model is to provide a kind of simple and compact for structure, efficiency of assembling
Main reducer in drive axle for construction machines housing apparatus, solve in the prior art each assembling parts of driving bridge main reducing speed assembly to main deceleration
After device shell, because precision can not reach the problem of requirement leads to bearing earlier period damage.
To achieve the above object, a kind of main reducer in drive axle for construction machines housing apparatus of the utility model includes bracket, a left side
Adjusting nut, left bearing lid, left bearing, bolt, right bearing lid, right adjusting nut, right bearing；The bracket and left bearing lid two
Person's casting is integrated, and the right bearing cover bolt is fixed on bracket；Differential assembly is installed by left bearing and right bearing
On the bearing hole at bracket both ends；It is locked respectively with left adjusting nut and right adjusting nut at the both ends of bracket.
The main reducer in drive axle for construction machines housing apparatus of above structure is on the basis of existing main reducing gear of drive axle shell
On, by the fusion of both bracket and one of bearing cap together, a monoblock type final drive casing is combined into, then will be another with bolt
A bearing cap is locked on final drive casing, is completed finally by machining is disposable.
A kind of main reducer in drive axle for construction machines housing apparatus of the utility model has the characteristics that and advantageous effect：
1st, by the fusion of both bracket and one of bearing cap together, it eliminates and is bolted, that is, reduce bolt use
Amount can reduce the production cost of drive axle.
2nd, only there are one bearing caps, reduce assembling link, save labour cost, while improve efficiency of assembling；
3rd, reduce each part faying face quantity, improve machining accuracy, final drive casing can ensure that two end axles install
With precision higher, solve the problems, such as that the prior art because the error that more assembling parts are brought leads to bearing damage, extends bearing
Service life improves product quality.
Description of the drawings
Fig. 1 is a kind of main reducer in drive axle for construction machines housing apparatus structure diagram of the utility model.
Reference numeral：Bracket 1, left adjusting nut 2, left bearing lid 3, left bearing 4, differential assembly 5, bolt 6, right bearing
Lid 7, right adjusting nut 8, right bearing 9.
Specific embodiment
A kind of main reducer in drive axle for construction machines shell dress to the utility model with reference to the accompanying drawings and detailed description
It puts and is described in further detail.
As shown in Figure 1, a kind of main reducer in drive axle for construction machines housing apparatus of the utility model includes bracket 1, left adjustment
Nut 2, left bearing lid 3, left bearing 4, bolt 6, right bearing lid 7, right adjusting nut 8, right bearing 9；The bracket 1 and left bearing
The casting of both lids 3 is integrated, and the right bearing lid 7 is fixed on bolt 6 on bracket 1；The differential assembly 5 passes through left bearing
4 and right bearing 9 be mounted on 1 both ends of bracket bearing hole on；At the both ends of bracket 1 respectively with left adjusting nut 2 and right adjustment spiral shell
Mother 8 locks.
Since both left bearing lid 3 and bracket 1 are casting together, and using disposable machining, the morpheme of part
Tolerance is guaranteed, and reduces 9 rigging error of left bearing 4, differential assembly 5 and right bearing, improves precision, is its normal work
It provides safeguard, while solves the problems, such as left bearing 4, the earlier period damage of right bearing 9 and differential assembly 5 early stage abrasion, significantly
Improve product quality.Further, since bearing cap there are one the main reducer in drive axle for construction machines housing apparatus of above structure,
Reduce bolt dosage, reduce the production cost of drive axle, while improve efficiency of assembling, save labour cost.
