Embodiment
The present invention can be explained in more detail by the following examples, the open purpose of the present invention is intended to the protection present invention In the range of all changes and improvements, the invention is not limited in the following examples:
With reference to a kind of head sheave of hoister sliding bearing non-transformer self-lubricate fueller shown in the drawings, the installation of this fueller At day wheel rim, each half brasses of loose wheel respectively with a set of,
Fueller includes oil drum 1, and oil drum 1 is connected by oil sucting one-way valve 2 with piston/cylinder 3, is provided with and resets in piston/cylinder 3 Spring 5 and piston rod 4, the lower end of piston rod 4 are provided with weight block 6, and the oil-out of piston/cylinder 3 is provided with oil outlet one-way valve 7, fuel-displaced list The grease exported to valve 7 is connected by pipeline with the brasses oil duct of sliding bearing 8.
The inside of oil drum 1 is provided with pressurization lid 9, and the bottom of pressurization lid 9 is provided with pressing spring 10, and the top of oil drum 1 is provided with note Hydraulic fluid port 11.
The oil sucting one-way valve 2 includes oil suction steel ball cone seat 12, oil suction steel ball 13 and oil suction bracket 14, and the oil suction is unidirectional Valve 2 is screwed in the right side screwed hole of piston/cylinder 3.
The oil outlet one-way valve 7 includes oil suction steel ball cone seat 15, oil suction steel ball 16 and oil suction bracket 17, and the oil suction is unidirectional Valve 7 is screwed in the left side screwed hole of piston/cylinder 3.
The piston/cylinder 3 is bolted on oil drum 1, and with sealing ring sealed connection.
Ferrule fitting 18 is provided with the oil-out of the oil outlet one-way valve 7 in the left side of piston/cylinder 3, ferrule fitting 18 passes through Pipeline is connected with the brasses oil-passage inlet of sliding bearing 8.
The piston/cylinder 3 is fixedly connected by bolt with oil drum 1.
The course of work:
In elevator each lifting cycle, changed from small to big in lifting speed by zero to maximum boost phase, head sheave velocity of rotation, The centrifugal force that the weight block 6 of fueller is subject to will be by zero to maximum, and the promotion piston rod 4 of weight block 6 overcomes the bullet of back-moving spring 5 Power, and opposing pistons cylinder body 3 moves up to range, the internal volume of piston/cylinder 3 is reduced, and grease is compressed in volume; Because oil sucting one-way valve 2 is closed, grease can not inversely return to oil drum 1 in cylinder body, can only be by going out under the promotion of piston rod 4 Oily check valve 7 is transported to sliding bearing 8, and therefore, fueller completes an oil extraction cycle in elevator boost phase;
In the decelerating phase of elevator, from large to small, the centrifugal force that the weight block 6 of fueller is subject to will be by for head sheave velocity of rotation Maximum under the elastic force effect of back-moving spring 5, promotes piston rod 4 to be moved downward together with the opposing pistons cylinder body 3 of weight block 6 to zero To original position, the increase of the internal volume of piston/cylinder 3, sealed volume is interior to produce vacuum;Because oil outlet one-way valve 7 is closed, sliding bearing 8 and Grease can not be inversely in return piston cylinder body 3 in pipeline, and because of vacuum action, the grease in oil drum 1 is passed through oil suction list by atmospheric pressure Delivered to valve 2 in piston/cylinder 3, will to refill grease in volume.Therefore, fueller is complete in the elevator decelerating phase Into an oil suction cycle;
Within each lifting cycle of elevator work, fueller will complete an oil suction, oil extraction action.So circulation, supply Grease is supplied sliding bearing by oily device by timing, quantitatively, automatically.
Above-described embodiment is the preferable embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment Limitation, other are any be away from Spirit Essence of the invention with made under principle change, modification, replacement, combine, simplification, Equivalent substitute mode is should be, is included in protection scope of the present invention.
