Description
Technical field
The utility model belongs to the application of bearing technology on the large special vehicle, relates generally to a kind of structural type of large special vehicle special angular contact ball bearing for liquid vortex flow retarder.
Background technique
At present, a kind of novel liquid vortex flow retarder auxiliary brake system that on the large-scale heavy duty automobile, adopts, it is characterized in that: the rotor of brake structure is connected with clutch with the main shaft flange respectively by two cover bearings, the separating and combine of Clutch Control main shaft flange and brake structure.When vehicle was not braked, clutch assembly was in not bonding state, and retarder does not operate; Only when vehicle was braked, clutch assembly just was in bonding state, and the retarder running is braked.Avoid the rotor idle running of retarder, saved the energy, reduced the suffered wearing and tearing of retarder, prolonged the working life of retarder effectively.This system has kept the running state of former automobile dynamic system, has guaranteed the ride quality of vehicle.Have period of braking short, prevent to break away, reduce characteristics such as tire wear, solved the traffic accident that causes that because of bringing to a halt tire splits cruelly etc. and cause.
But, be installed in the inefficacy in advance of the deep groove ball bearing of retarder braking device fixed end, make have to frequent maintenance and more renew bearing of vehicle, shortened the maintenance period of vehicle, increased the maintenance expenses of vehicle.Deep groove ball bearing has rotating speed height, simple in structure, can carry higher radial load, can carry the characteristics of certain bi-directional axial load again, but can not bear radial and axial joint load simultaneously, especially can not bear bigger axial load.
Summary of the invention
The purpose of this utility model provides a kind of special angular contact ball bearing, be installed in the fixed end of retarder braking device, this bearing has compact structure, rotating speed height, long service life, greasy property is good, rotation is flexible, the characteristics stably that turn round, and can bear radial and axial joint load simultaneously.2800 rev/mins of anxious stopping times, bearing can not produce heating phenomenon such as stuck, and cheap for manufacturing cost, easy for installation.
The purpose of this utility model can adopt following technological scheme to realize: it comprises outer ring, inner ring, steel ball, retainer.Bearing contact angle α is 25 °; The outer ring large end face of widening, raceway is set for the eccentric, raceway point with lock; The inner ring large end face of widening, raceway is set for the eccentric, raceway point with lock; Retainer is the mode of inner ring rib guiding; The angle beta of retainer is 40 °, and the angle [alpha] 1 in retainer pocket hole is 25 °, and top, pocket hole is cylindrical body, makes things convenient for packing into of steel ball when bearing assembles, and bottom, pocket hole is that the billiard table body is that camber line contacts with the rolling surface of steel ball.
By last structure as can be seen, the bearing contact angle α of the utility model design is 25 °, and the design of this angle is in order to make bearing can either carry radial load, can to carry axial load again simultaneously; The large end face of outer ring is widened as much as possible, to increase the frictional force of end face and clutch-plate, the design of the off-centre of outer ring raceway is in order to make bearing can carry bigger axial force, and the design of outer ring raceway point with lock had both guaranteed the matching requirements of bearing, had solved the sequence of sanqu songs within a particular musical mode problem of bearing simultaneously again; The large end face of inner ring is widened as much as possible, to strengthen the faying surface of end face and main shaft flange, the off-centre design of inner ring raceway is in order to make bearing can carry bigger axial force, the design of inner ring raceway point with lock had both guaranteed the matching requirements of bearing, had solved the sequence of sanqu songs within a particular musical mode problem of bearing simultaneously again; Retainer is the mode of inner ring rib guiding; The angle beta of retainer is designed to 40 °, avoid interference with inner ring and outer ring rib, the angle [alpha] 1 in retainer pocket hole is identical with the wrapping angle α of bearing to be 25 °, guaranteeing that bearing rotates requirement flexibly, optimize the shape in retainer pocket hole, retainer pocket hole is designed to the structural type that cylindrical body and billiard table body join, top, pocket hole is cylindrical body, make things convenient for packing into of steel ball when bearing assembles, bottom, pocket hole is that the billiard table body is that camber line contacts with the rolling surface of steel ball, makes the running of bearing more steady.In sum, the utlity model has compact structure, rotating speed height, long service life, greasy property is good, rotation is flexible, running is steady, can bear radial and axial joint load simultaneously.2800 rev/mins of anxious stopping times, bearing can not produce heating phenomenon such as stuck, and cheap for manufacturing cost, easy for installation.
