Abstract
The present invention relates to a double-side grease filling system for a bearing, which belongs to the technical field of grease filling for bearings. The present invention is composed of an upper grease filling device and a lower grease filling device, wherein the upper grease filling device is composed of an end cover 1, a shaft 2, an upper casing 3, an upper greasing filling mouth 4 and an upper guide sleeve 8, and the lower grease filling device is composed of a cover 5, a lower greasing filling mouth 6, a lower guide sleeve 7, a shaft 9 and a lower casing 10; inlet air and outlet air of air holes control the upward and downward movement of the shaft on the upper grease filling device; when grease is filled, the upper grease filling mouth enters a gap in an inner lane of the bearing to fill grease, and the lower grease filling mouth enters a gap in an outer lane of the bearing to fill grease; after filled, the grease is uniformly spread in gaps between each roller of the bearing, the grease filling quantity is controlled by a proportion valve, and the grease filling quantity of the upper grease filling mouth is identical to that of the lower grease filling mouth. The present invention has the advantages that after the grease is filled, the grease filling quantity is uniform and stable, and grease sticking phenomena are few.
Description
Technical field
The invention belongs to bearing greasing technical field.
Background technique
The biserial circle Roller Shaft of producing at present must be annotated lubricating grease technology, adopts the middle greasing structure of single head for a long time in the Production of bearing industry always, and there are the following problems in long-term the use for this structure:
1. annotate lubricating grease amount instability.The lubricating grease amount of single cover bearing does not wait in a collection of bearing, and relatively reasonable greasing amount more or less, has influenced the long-term working life of bearing.
2. in circumferencial direction fat irrational distribution.Our experiments show that, the place that lubricating grease is few, bearing temperature rise occurs easily dynamically the time, and phenomenons such as " hot boxs " has a strong impact on comprehensive working life of bearing, and many local of lubricating grease easily produces serious the leakage.
3. be stained with fat.This kind structure has remaining lubricating grease to amass at the greasing head edge when lifting behind greasing head, cause the lubricating grease amount of annotating in the bearing to reduce the working life of having reduced bearing.
4. the easy leakage of oil of hydraulic control.
Summary of the invention
Purpose of the present invention just provide a kind of greasing amount evenly, stablize, be stained with the light bearing bilateral greasing system of fat phenomenon.
Technical solution of the present invention is, a kind of bearing bilateral greasing system, form by grease filler and Pneumatic actuator, grease filler comprises the last grease filler that is made of end cap 1, axle 2, upper shell 3, upper grease infusing mouth 4 and upper guide bush 8, axle 2 passes the end cap 1 that is connected with upper shell 3, upper guide bush 8 is installed between axle 2 and the upper shell 3, and upper grease infusing mouth 4 is connected with axle 2
A. grease filler also comprises the following grease filler that is made of lid 5, lower grease infusing mouth 6, following guide pin bushing 7, axle 9 and lower shell body 10,
B. Pneumatic actuator is made up of air pump 15, gas flow controller 16, proportional valve 11 and proportional valve 12, and air pump 15 is connected with gas flow controller 16, and gas flow controller 16 is connected with pore 13, pore 14, proportional valve 11 and proportional valve 12,
Upper grease infusing mouth 4 is connected with proportional valve 11, and lower grease infusing mouth 6 is connected with proportional valve 12.
Gas flow controller is handled three linked piece, manifold valve and valve plate by source of the gas and is constituted.
It is QLPY2 15 04 26T2 that source of the gas is handled the three linked piece model, and the manifold valve model is: 1 SR561-CE38DW, 4 SR561-RE38DW and 1 MF561E-06A.
The turnover gas Control Shaft 2 of pore 13 and pore 14 moves up and down, during greasing, upper grease infusing mouth 4 enters the greasing of bearing inner race space, lower grease infusing mouth 6 enters the greasing of bearing outer ring space, fat evenly divides in slit between each roller of bearing after the greasing, greasing amount is by proportional valve 11 and proportional valve 12 controls, and greasing amount equates up and down.
The invention has the beneficial effects as follows that greasing amount is even after the greasing, stable, it is light to be stained with the fat phenomenon.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a hydraulic system schematic representation of the present invention.
Wherein, 1. end cap, 2. spool, and 3. upper shell, 4. upper grease infusing mouth, 5. lid, 6. lower grease infusing mouth 7. descends guide pin bushing, 8. upper guide bush, 9. spool, 10. lower shell body, 11. proportional valves, 12. proportional valves, 13. pores, 14. pores, 15. air pumps, 16. gas flow controllers.
Embodiment
Upper grease infusing mouth 4 is connected with proportional valve 11, and lower grease infusing mouth 6 is connected with proportional valve 12.
Bilateral is greasing simultaneously up and down, the control of employing pneumatic system, the turnover gas Control Shaft 2 of pore 13 and pore 14 moves up and down, during greasing, upper grease infusing mouth 4 enters the greasing of bearing inner race space, and lower grease infusing mouth 6 enters the greasing of bearing outer ring space, and fat evenly divides in slit between each roller of bearing after the greasing, greasing amount is by proportional valve 11 and proportional valve 12 controls, and greasing amount equates up and down.
This kind structure can accurately be felt relieved to bearing, goes up lower grease infusing mouth during greasing and imbeds the inside and outside inner room space of bearing, and a plurality of greasings hole of circumference uniform distribution is injected into lubricating grease between each roller of bearing simultaneously, and greasing is even.
