(III) advantageous effects

The invention provides an oiling device for a shaft sleeve at the tail part of a hoist. The method has the following beneficial effects:

1. this lifting machine afterbody axle sleeve filling device, because the oil pocket has been seted up to the inside of overcoat, and the top of oil pocket switches on has, crosses the oil pocket, and simultaneously, the hard friction of endotheca and overcoat has been solved in the setting of oil pocket, has stopped the noise that sends by the friction, and the change that arouses structure precision is aroused in generating heat that the friction arouses.

2. This lifting machine afterbody axle sleeve filling device, because the driving piece is electric putter, and the setting of oil storage tank can be very convenient control through its inside volume of atmospheric pressure single suction, and when the in-process of sending oil, the setting that piston sleeve and oil storage tank inside wall tightly laminated, can be with the inside of the comparatively thorough crowded oil pipe of the inside lubricating oil of oil storage tank, the inside to the bearing frame of comparatively thorough addition of the lubricating oil that this equipment can be quantitative will need to add promptly, it is higher to the utilization ratio of lubricating oil, the too much or too little phenomenon of volume of adding can not appear.
