Abstract
The utility model relates to a hinge bearing for a rear axle and frame of an off-road rigid dump truck, and belongs to the field of bearings. According to the utility model, a bearing inner ring and a bearing outer ring are both separated into two half round rings, and are matched through a spherical surface; a first circumference oil groove is arranged in an outer cylinder surface of the bearing outer ring, and a second a first circumference oil groove and a longitudinal oil groove are arranged in an inner spherical surface of the bearing outer ring; and the first circumference oil groove, the second circumference oil groove and the longitudinal oil groove are communicated through radial oil holes. The inner ring of the hinge bearing is welded on a middle crossbeam of the frame, the outer ring of the hinge bearing is mounted in a bearing case at the front end of the rear axle, the outer ring is matched with the inner ring through the spherical surface, and two halves of the bearing case are connected through a bolt. The outer ring can rotate around the middle crossbeam of the frame, so that the stress on the frame can be lowered, and the service life of the frame can be prolonged; and at the same time, enough service life of the bearing as well as conveniences in lubrication and maintenance are ensured.
Description
Technical field
The utility model relates to the anchor bearing of a kind of non-highway rigidity dumping car back axle and vehicle frame, belongs to field of bearings.
Background technique
Non-highway rigidity dumping car (hereinafter referred is the rigidity car) is the on-the-spot mainstream car design of using of domestic each large-scale mine, water conservancy construction; The The Enlargement Tendency of rigidity car was obvious in recent years, and the most important structural member of this car of will demanding perfection also is the core skeleton on chassis---and vehicle frame has enough working life.General rigidity car all is that the joint shaft bearing of employing standard is hinged with back axle and vehicle frame; And the joint shaft bearing of the standard on-detachable total member that is inside and outside circle; Two blocks of parallel-plates that this just requires on the middle cross beam of vehicle frame welding and beam vertical respectively have a circular hole, two circular hole equal and opposite in directions and coaxial on the two boards; The axis in hole is parallel with the vehicle frame middle cross beam; The size in hole is close with the joint shaft bearing endoporus, and joint shaft bearing is installed in the bearing support of back axle, through the welded plate on joint shaft bearing and the vehicle frame middle cross beam back axle and vehicle frame is coupled together (see figure 1) with bearing pin again.This traditional Placement is equivalent on the middle cross beam of vehicle frame, stretch out a cantilever bracket; Its consequence is that the thrust of car back axle when operation has produced very large torsional load and passed to vehicle frame through this cantilever; Make vehicle frame bear huge failing stress, reduced working life.
Summary of the invention
The purpose of the utility model provides and a kind ofly can reduce the stress that vehicle frame bears, and prolongs the working life of vehicle frame; Guarantee working life and lubricated easily and the non-highway rigidity dumping car back axle of maintenance and the anchor bearing of vehicle frame that bearing is enough simultaneously.
Technical solution is:
The utility model comprises: bearing inner race, bearing outer ring; Bearing inner race, bearing outer ring are divided into two semicircular rings; Bearing outer ring cooperates with sphere with bearing inner race; The external cylindrical surface of bearing outer ring is provided with first circumference oil groove, and the bearing outer ring inner ball surface is provided with second circumference oil groove and vertical oil groove, and first circumference oil groove, second circumference oil groove and vertical oil groove are connected through radial direction oil hole.
The utility model inner ring is welded on the middle cross beam of vehicle frame, and the outer ring is installed in the bearing housing of back axle front end, and the outer ring cooperates with sphere with inner ring, and the two halves of bearing housing connect with bolt.The outer ring can be rotated around the middle cross beam of vehicle frame, reduces the stress to vehicle frame, prolongs the working life of vehicle frame; Guarantee working life and lubricated easily and maintenance that bearing is enough simultaneously.

Embodiment
The utility model bearing inner race 1 all is divided into two semicircular rings with bearing outer ring 2, so just can inner ring 1, the bearing outer ring 2 of bearing can be installed separately easily; Bearing inner race 1 is welded on the middle cross beam 4 of vehicle frame 3; Being used for the bearing housing 6 of installation shaft bearing outer-ring 2 is parts of back axle 5, and bearing housing and back axle 5 all are welded with forging and steel plate, and bearing outer ring 2 is installed in the bearing housing 6 of back axle front end, and the two halves of bearing housing 6 connect with bolt 7; Bearing outer ring 2 and bearing inner race 1 cooperate with sphere.Bearing inner race 1 is processed with mechanical property and the good alloyed steel of heat treatment performance, and bearing outer ring 2 is processed with the poor slightly Cuprum alloy of performance.The steel inner ring of bearing has endoporus and outer spherical surface; The external cylindrical surface of bearing copper outer ring 2 is provided with first circumference oil groove 8; Second circumference oil groove 9 and vertical oil groove 10 on 2 inner ball surface of bearing copper outer ring; Second circumference oil groove 9 communicates with vertical oil groove 10, and the radial direction oil hole 11 that connects bearing copper outer ring 2 couples together first circumference oil groove 8, second circumference oil groove 9 and vertical oil groove 10 oil grooves of inner and outer surface; Lubricating grease gets into earlier the bearing housing 6 of back axle during use through extraneous pipeline, again the upper oil hole 11 through bearing copper outer ring 2 and first circumference oil groove 8, second circumference oil groove 9 and vertically oil groove 10 oil grooves arrive and be distributed to the fitting surface of Bearing Steel inner ring 1 and bearing copper outer ring 2.The driving wheel trailing wheel rotates, and passes to back axle for the frictional force of tire on ground, and back axle passes to bearing with the form of thrust again and acts on then and drive car load on the vehicle frame.
The installation of this back axle and bearing makes a middle cross beam bearing thrust of vehicle frame, has eliminated whole torsional loads, has greatly reduced the failing stress that vehicle frame bears, and is very beneficial for the maintenance of bearing and the working life of assurance vehicle frame.
