Abstract
A rolling bearing sliding block type connecting rod oil-free lubricating compressor is provided with a rolling bearing sliding block type connecting rod mechanism, wherein a rolling bearing is installed on a crank to replace the movement of a sliding block in a chute, and changes the sliding friction into the rolling friction. A chute on a connecting rod is a kidney slot, the clearance between the slot width and the outer diameter of the bearing is a precision movable fit clearance, and the arc center distance on the two ends of the slot is two times of the eccentricity of the crank. The bearing can make the transverse reciprocating movement in the chute under the driving of the crank, thereby driving a connecting rod piston to make the longitudinal reciprocating movement. The bearing and the chute are in the rolling friction without lubrication. The piston of the utility model adopts an oil-free lubricating piston filled with graphite polytetrafluoroethylene, thereby forming a novel rolling bearing sliding block type connecting rod oil-free lubricating compressor. Therefore, the rolling bearing sliding block type connecting rod oil-free lubricating compressor not only remains the original advantages thereof, but also realizes the oil-free lubrication, and enlarges the application field.
Description
Affiliated technical field
The utility model relates to a kind of rolling bearing slide block type connecting rod non-lubricated compressor, especially has the non-lubricated compressor of rolling bearing slide block type connecting rod that can oil-free lubrication.
Technical background
At present, known slide block type connecting rod structure is made up of with the connecting rod that has chute the columned slide block that is connected on the crankshaft.Compare with shuttle-type connecting rod, the connecting rod of slide block type linkage mechanism is only done longitudinal movement, and transverse movement has slide block to finish, and has reduced the lateral force of piston.Has the advantage that improves compressor efficiency and prolong piston life.But owing to be sliding friction between slide block and the chute, must be that oil lubrication is arranged, limit the application in non-lubricated compressor.
Summary of the invention
In order to overcome the deficiency of slide block type linkage mechanism, the utility model provides a kind of rolling bearing slide block type connecting rod non-lubricated compressor, this compressor has a kind of rolling bearing slide block type linkage mechanism, make it both have original advantage, can also realize the purpose of oil-free lubrication, enlarge application.
The technological scheme that its technical problem that solves the utility model adopts is: a rolling bearing is installed on crank, is replaced slide block to move in chute, changing sliding friction is rolling friction.Chute structure on the connecting rod is a kidney slot, and the crack is accurate gap movingly between groove width and the bearing outside diameter, and center of arc's distance at groove two ends is two times of the eccentricity of crank.Bearing under the drive of crank, transverse reciprocating motion in chute, the vertical to-and-fro motion of drivening rod piston.Be rolling friction between bearing and the chute, need not lubricate.Piston of the present utility model adopts the filling graphite teflon piston of oil-free lubrication, constitutes novel rolling bearing slide block type connecting rod non-lubricated compressor.Reach the purpose of this utility model.
The beneficial effects of the utility model are, can both have the advantage of slide block type connecting rod, can realize oil-free lubrication again, have enlarged the use field, and simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a rolling bearing slide block type connecting rod non-lubricated compressor structural drawing plan view
Schematic representation when Fig. 2 is the link motion of rolling bearing slide block type to left stop
1. motors among the figure, 2. lock screw, 3. crank, 4. bearing, 5. chute cover, 6. connecting rod cap, 7. connecting rod, 8. filling graphite teflon piston ring, 9. piston, 10. screw.
Embodiment
In Fig. 1, crank (3) is fixed on motor (1) axle with lock screw (2), bearing (4) is installed on the crank (3), a wear-resisting chute cover (5) is arranged in connecting rod (7) chute, connecting rod cap (6) is in order to prevent that bearing (4) from deviating from, fill graphite teflon piston ring (8) and be pressed on the piston (9), form integrated type oil-free lubrication piston, use screw (10) to be fixed on the connecting rod (7) again.Other compressor arrangement and routine are as good as.
In Fig. 2, when crank (3) moves to left stop as can be seen, the motion state of bearing (4) connecting rod (7) piston (9).Bearing under the drive of crank, transverse reciprocating motion in chute, the vertical to-and-fro motion of drivening rod piston simultaneously, connecting rod does not have the swing of left and right directions, has eliminated the lateral force that acts on the piston substantially, prolongs the life-span of piston, has improved compressor efficiency.Bearing outer ring rolls on runner wall, does not have sliding friction, also just need not have lubricatedly, realizes the oil-free lubrication of connecting rod.
The different choice of mentioned bearing type in above-mentioned embodiment all belongs to the protection domain of technical solutions of the utility model.
The mentioned connecting rod chute and the different choice of oil-free lubrication piston structure in above-mentioned embodiment all belong to the protection domain of technical solutions of the utility model.
Claims (2)
