Abstract
Damping gas thrust bearing is exactly to utilize gases at high pressure to isolate axle wheel (3) and the cylinder sleeve (2) holding axle, axle wheel (3) does not produce friction when rotating in cylinder sleeve (2), simultaneously, axle wheel (3) changes with the load-bearing change of hanging axis (6) moment with the distance of hanging axis (6), thus plays the effect of damping.The social benefit of the present invention is exactly laborsaving, damping.
Description
Technical field
The present invention relates to a kind of undertaking rotating shaft device, be applied especially to the hanging axis of vehicle.
Background technology
Existing axle bearing is all inner ring and the outer ring isolating with ball or roller bearing and holding axle, and its shortcoming is: can produce rolling friction when rotating in inner ring and outer ring, consumes power, produces heat, and the easy elevated temperature deformation of bearing is damaged.
Summary of the invention
The present invention is exactly to utilize gases at high pressure to isolate axle wheel 3 and the cylinder sleeve 2 holding axle, and axle wheel 3 does not produce friction when rotating in cylinder sleeve 2, meanwhile, axle wheel 3 changes with the load-bearing change of hanging axis 6 moment with the distance of hanging axis 6, thus plays the effect of damping.
The social benefit of invention is exactly laborsaving, damping.
The technical solution adopted in the present invention is such that damping gas thrust bearing and includes that axle wheel 3 is placed in cylinder sleeve 2, rotary shaft 4 is through cylinder sleeve 2 and axle wheel 3,3 are taken turns with pivot pin 5 fixed bias circuit 4 and axle, top cover 1 is installed valve 7, being tamping at the two ends of cylinder sleeve 2 with 11 top covers 1 of screw again, such axle wheel about 3 all forms sealing space；Hanging axis 6 is fixed on the symmetric position on cylinder sleeve 2 both sides；Entangle at rotary shaft 4 two ends needle bearing 10, again needle bearing 10 is inserted in slide block 8, wale at slide block 8 two ends chute 9, be fixed on cylinder sleeve 2 with 11 chutes 9 of screw, make rotary shaft 4 vertical with cylinder sleeve 2 medial surface all the time；The lubricating oil oozed out in reclaiming cylinder sleeve 2 with high-pressure oil pump and high-pressure pump and air, be more again pressed in cylinder sleeve 2 by valve 7.
Accompanying drawing explanation
Fig. 1 is the present invention each modular construction figure.
Fig. 2 is exterior sideview figure of the present invention.
In Fig. 1, Fig. 2: 1 top cover, 2 cylinder sleeves, 3 axle wheels, 4 rotary shafts, 5 pivot pins, 6 hanging axises, 7 valves, 8 slide blocks, 9 chutes, 10 needle bearings, 11 screws.
Detailed description of the invention
Shown in Fig. 1, hanging axis 6 carries weight, the sealing space taking turns about 3 at axle adds a certain amount of lubricating oil to increase air tightness and lubricity, add a certain amount of high pressure gas until the axial line of rotary shaft 2 just stops increasing calming the anger in same level with the axial line of hanging axis 6, so, during vibrations, cylinder sleeve 2 would not collide with axle wheel 3, axle wheel 3 also will not contact with top cover 1, taking turns 3 contact positions inside cylinder sleeve 2 with axle is not the most load-bearing direction, and simply gentle touchdown, so axle wheel 3 rotations cylinder sleeve 2 in, do not produce friction；When lubricating oil or air ooze out, available high-pressure oil pump and high-pressure pump are reclaimed and are again pressed in cylinder sleeve 2 by valve 7, and the sealing space making axle take turns about 3 remains lubricity and air tightness；Although shaking, accelerating, when braking, needle bearing 10 the most also can bearing pressure and produce certain frictional force, but be also the less frictional force of moment, the least to vehicle influence on system operation.
Claims (4)
1. damping gas thrust bearing, including: axle wheel (3) is placed in cylinder sleeve (2), rotary shaft (4) is through cylinder sleeve (2) and axle wheel (3), (3) are taken turns with pivot pin (5) fixed bias circuit (4) and axle, it is characterized in that: valve (7) is installed on top cover (1), with screw (11), top cover (1) being tamping at the two ends of cylinder sleeve (2) again, such axle wheel (3) the most all forms sealing space.
Damping gas thrust bearing the most according to claim 1, is characterized in that: hanging axis (6) is fixed on the symmetric position on cylinder sleeve (2) both sides.
Damping gas thrust bearing the most according to claim 1, it is characterized in that: entangle at rotary shaft (4) two ends needle bearing (10), again needle bearing (10) is inserted in slide block (8), wale at slide block (8) two ends chute (9), with screw (11), chute (9) is fixed on cylinder sleeve (2), makes rotary shaft (4) vertical with cylinder sleeve (2) medial surface all the time.
Damping gas thrust bearing the most according to claim 1, is characterized in that: the lubricating oil oozed out in reclaiming cylinder sleeve (2) with high-pressure oil pump and high-pressure pump and air, is more again pressed in cylinder sleeve (2) by valve (7).
