Disclosure of Invention
The utility model aims at overcoming the defects and providing a loader drive axle main reducer oil seal dustproof structure with simple structure, convenient manufacture and maintenance and good dustproof effect, which solves the following two problems in the prior art that ①, a dustproof cover formed by 1mm punch forming is welded on a flange spigot, the outer circle of the dustproof cover is exposed outside, the dustproof cover is easy to deform and abrade due to the collision of foreign objects due to thin thickness to cause abnormal sound, the size and the behavior tolerance of the dustproof cover formed by punch forming are poor, the dustproof cover and the sealing cover need to be designed into a larger gap to influence the dustproof effect for preventing interference, ②, the dustproof cover and the flange are moving rotating pieces, the axial direction of the oil seal is only limited by one end, the oil seal is easy to incline or move integrally during the assembly of test gas when the size of the oil seal installation position of a specific sealing cover is poor, until the flange is interfered, and the oil seal abrasion fault is caused.
In order to achieve the purpose, the utility model discloses loader transaxle main reducer oil blanket dustproof construction includes lock nut, flange, dust guard, bolt, sealed lid, bearing frame, bracket, spiral bevel gear, lower bearing, bearing spacer, upper bearing, oil blanket and snap ring; the flange is locked on the spiral bevel gear by a locking nut; the spiral bevel gear is borne on a bearing seat by an upper bearing and a lower bearing, a bearing spacer bush for adjusting the gap is arranged between the upper bearing and the lower bearing, and the bearing seat is arranged on an installation hole of the bracket and is flatly attached to the upper end face; the sealing cover is arranged at the upper end of the bearing seat, and the sealing cover and the bearing seat are fixed on the bracket through bolts; the oil seal is arranged in the mounting hole of the sealing cover, the inner hole at the upper end of the sealing cover is provided with a clamping ring groove, and a clamping ring arranged at the upper end of the oil seal is arranged in the clamping ring groove of the sealing cover so as to limit the axial movement of the oil seal and avoid the inclination and movement of the oil seal in the process of assembling and testing gas; the dust guard adopts machine tooling shaping, sinks the up end of sealed lid during the installation to the protection dust guard collides with the deformation and the sealed lid of wearing and tearing, in order to improve dustproof effect.
The thickness of the dust-proof plate is 5 mm.
The loader drive axle main reducer oil seal dustproof structure has the following technical characteristics and beneficial effects:
1. the dust-proof plate with the thickness of 5mm is adopted for dust prevention, and the end face of the sealing cover is heightened, so that the dust-proof plate is sunk into the end face of the sealing cover, the collision and deformation of the dust-proof plate can be effectively protected, and the sealing cover is prevented from being abraded; meanwhile, the dust guard is formed by machining, so that the size and form and position tolerance can be guaranteed, a smaller gap between the dust guard and the sealing cover can be designed, and the dust-proof effect is improved.
2. Through increasing the snap ring groove in sealed upper end, the installation snap ring during the assembly can restrict oil blanket axial float, avoids causing the oil blanket to be released by atmospheric pressure at the assembly gas testing in-process and leads to the oil blanket slope, remove to reduce oil blanket wearing and tearing oil leak fault rate.
Drawings
Fig. 1 is the main schematic sectional view of the oil seal dustproof structure of the main speed reducer of the loader drive axle of the utility model.
Reference numerals: the device comprises a locking nut 1, a flange 2, a dust guard 3, a bolt 4, a sealing cover 5, a bearing seat 6, a bracket 7, a spiral bevel gear 8, a lower bearing 9, a bearing spacer 10, an upper bearing 11, an oil seal 12 and a clamping ring 13.
Detailed Description
The following provides a further detailed description of the dustproof structure of the main reducer oil seal of the loader drive axle according to the present invention with reference to the accompanying drawings and the detailed description.
