Abstract
The utility model discloses a bearing double-side grease filling device, pertaining to the technical filed of bearing filling. The utility model consists of a upper grease filling device and a lower grease filling device; wherein, the upper grease filling device consists of a cover 1, an axis 2, an upper housing shell 3, an upper grease filling mouth 4 and an upper sleeve 8; the lower grease filling device consists of a cover 5, a lower grease filling mouth 6, a lower sleeve 7, an axis 9 and a lower housing shell 10. The air-in and air-out of the stomata controls the fluctuation of the upper grease filling device. When in grease filling, the upper grease filling mouth enters the spacing of the bearing inner circle, the lower grease filling mouth enters the bearing outer circle, the grease is distributed equally in the gaps of each bearing roller after filling, the quantity of grease filling is controlled by ration valve, the upper and lower grease fillings are balanced in quantity. The utility model has good effect of balanced quantity in grease filling, stabilization and less grease staining.
Description
Technical field the utility model belongs to bearing greasing technical field.
The biserial circle Roller Shaft that background technique is produced 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.
The summary of the invention the purpose of this utility model just provide a kind of greasing amount evenly, stablize, be stained with the light bearing bilateral grease filler of fat phenomenon.
Technical solution of the present utility model is, a kind of bearing bilateral grease filler, comprise the last grease filler that constitutes by 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, upper grease infusing mouth 42 is connected with axle, its special, also comprise by lid 5, lower grease infusing mouth 6, guide pin bushing 7, spools 9 and the following grease filler that constitutes of lower shell body 10 down.
Upper grease infusing mouth 4 is connected with proportional valve 11, and lower grease infusing mouth 6 is connected with proportional valve 12.
End cap 1 is provided with pore 13, and upper shell 3 is provided with pore 14.
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 1 SR561-CE38DW of manifold valve, 4 SR561-RE38DW and 1 MF561E-06A constitute.
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 beneficial effects of the utility model are, greasing amount is even after the greasing, and are stable, and it is light to be stained with the fat phenomenon.
Description of drawings Fig. 1 is a structural representation of the present utility model.
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.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments for embodiment.
Axle 2 passes the end cap 1 that is connected with upper shell 3, and upper guide bush 8 is installed between axle 2 and the upper shell 3, and upper grease infusing mouth 4 is connected the last grease filler of formation with axle 2; Lid 5, lower grease infusing mouth 6, following guide pin bushing 7, axle 9 and lower shell body 10 constitute grease filler down.
Upper grease infusing mouth 4 is connected with proportional valve 11, and lower grease infusing mouth 6 is connected with proportional valve 12.
End cap 1 is provided with pore 13, and upper shell 3 is provided with pore 14.
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.
