Abstract
The utility model discloses an auxiliary supporting device of a passive spiral bevel gear of a driving axle. The auxiliary supporting device comprises a sleeve, a thrust bolt, a nut, a thrust washer and a main speed reducer shell. The main speed reducer shell is additionally provided with a threaded hole, the sleeve is installed on the thrust bolt, the thrust bolt penetrates through the threaded hole to be locked on the main speed reducer shell through the nut and the thrust washer, and therefore the auxiliary supporting device of the passive spiral bevel gear is formed below the passive spiral bevel gear. The auxiliary supporting device of the passive spiral bevel gear of the driving axle solves the problems that due to the fact that the passive spiral bevel gear is large in circumference and high in load, the passive spiral bevel gear is prone to deforming under the condition that no auxiliary support exists, so that gears are damaged, have abnormal sound, are high in temperature and the like.
Description
Technical field
The utility model relates to axle reduction structure, particularly main reducer in drive axle for construction machines assembly.
Background technique
China's 50 loader ransaxles generally adopt conventional construction main gearbox assembly at present, power is inputted by input flange, be delivered to passive spiral bevel gear by spiral bevel driving gear, passive spiral bevel gear and differential assembly are fixed together, by the bevel gear in differential assembly and differential gear by transmission of power to the assembly of wheel limit, increased moment of torsion thereby reduced rotating speed.In loader work, the moment of torsion of output usually moment reach maximum value, because of passive spiral bevel gear circumference large, and without supplemental support, the load of bearing is large, easily deforms, thereby cause the faults such as gear failure, abnormal sound, high temperature, greatly reduce the benefit of enterprise.
Summary of the invention
The purpose of this utility model is to provide the passive spiral bevel gear auxiliary support apparatus of a kind of ransaxle, solve passive spiral bevel gear because the load that circumference is large, bear is large, problems such as causing gear failure, abnormal sound, high temperature easily deforms in without supplemental support situation.
For realizing above object, the utility model is set up passive spiral bevel gear auxiliary support apparatus in main reducing gear of drive axle assembly, and the passive spiral bevel gear auxiliary support apparatus of this ransaxle comprises cover, thrust bolt body, nut, thrust washer and bevel housing; On described bevel housing, increase a tapped hole, described cover is arranged on thrust bolt body, be locked on bevel housing through tapped hole by nut and thrust washer, thereby below passive spiral bevel gear, form passive spiral bevel gear auxiliary support apparatus.
The passive spiral bevel gear auxiliary support apparatus design of above-mentioned ransaxle has following characteristics:
1, increase by one and greatly improved by the bearing capacity of spiral bevel driving gear by spiral bevel driving gear auxiliary support apparatus, reduce distortion.
2, the cover material of the front end of auxiliary support apparatus is copper, reduces in the time that passive spiral bevel gear deforms the wearing and tearing between umbrella gear and cover.
3, on bevel housing, increase a tapped hole, be convenient to the installation of auxiliary support apparatus.
The passive spiral bevel gear auxiliary support apparatus of this ransaxle has well solved, and load large because of passive spiral bevel gear circumference, that bear is large, thereby easily deform problems such as causing gear failure, abnormal sound, high temperature at conventional construction without supplemental support in the situation that, greatly improved the benefit of enterprise.
Accompanying drawing explanation
Accompanying drawing is the main cross-sectional schematic of the passive spiral bevel gear auxiliary support apparatus of the utility model ransaxle.
Reference character: input flange 1, spiral bevel driving gear 2, clutch shaft bearing 3, bearing support 4, the second bearing 5, bracket 6, passive spiral bevel gear 7, differential assembly 8, the 3rd bearing 9, adjusting nut 10, bearing cap 11, cover 12, thrust bolt body 13, nut 14, thrust washer 15.
Embodiment
Below in conjunction with the drawings and specific embodiments, the passive spiral bevel gear auxiliary support apparatus of the utility model ransaxle is described in further detail.
The passive spiral bevel gear auxiliary support apparatus of the ransaxle of the utility model shown in accompanying drawing, comprise cover 12, thrust bolt body 13, nut 14 and thrust washer 15, on bevel housing 6, increase a tapped hole, cover 12 adopts copper material to make and be arranged on thrust bolt body 13, be locked on bevel housing 6 by nut 14 and thrust washer 15, thereby below passive spiral bevel gear, form passive spiral bevel gear auxiliary support apparatus.Power is inputted by input flange 1, be delivered on passive spiral bevel gear 7 by spiral bevel driving gear 2, spiral bevel driving gear 2 is fixed on bracket 6 by clutch shaft bearing 3, bearing support 4 and the second bearing 5, passive spiral bevel gear 7 is fixed together with differential assembly 8, differential assembly 8 is fixed on bracket 6 by the 3rd bearing 9, adjusting nut 10 and bearing cap 11, the bevel gear by 8 li of differential assemblies and differential gear by transmission of power to the assembly of wheel limit.In loader work, the moment of torsion of output usually moment reach maximum value, passive spiral bevel gear 7 deforms, and 12 rubs with cover, reduces passive spiral bevel gear and is out of shape, and has played the effect of supplemental support.
Claims (1)
1. the passive spiral bevel gear auxiliary support apparatus of ransaxle, is characterized in that: it comprises cover, thrust bolt body, nut, thrust washer and bevel housing; On described bevel housing, increase a tapped hole, described cover is arranged on thrust bolt body, be locked on bevel housing through tapped hole by nut and thrust washer, thereby below passive spiral bevel gear, form passive spiral bevel gear auxiliary support apparatus.
