Background
With the increasing popularization of the installation and use of escalators and sidewalks, the use and maintenance of equipment components are always very concerned, and how to effectively maintain the equipment components is very important.
At present, after a plurality of escalators or sidewalks are used for a long time, various strange abnormal sounds can occur in the operation process of equipment, wherein one abnormal sound is generated by friction between a step shaft and a shaft sleeve, the operation time is too long, particularly, under the outdoor environment, grease lubricated between the step shaft and the shaft sleeve is too fast lost due to the invasion of rainwater, and the operation abnormal sound can be caused if the grease is not timely and effectively supplemented, so that the riding and transporting comfort is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can refuel and long-term step axle sleeve that stores up grease, use the back for a long time with current many escalators or pavement that provide in solving above-mentioned background art, various strange abnormal sounds can take place among the equipment operation process, wherein there is a condition just the abnormal sound that sends from step axle and axle sleeve room friction, because operation duration overlength, especially under the outdoor environment, because of the invasion of rainwater, lubricated grease runs off too fast between step axle and axle sleeve, if do not have timely effectual supplementary lubricating grease, will cause the abnormal sound of operation, thereby influence the problem of taking advantage of the travelling comfort.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a can refuel and long-term step axle sleeve that stores up grease, includes the axle sleeve body, the inside fixed mounting of axle sleeve body has three annular oil storage tank, and is three annular oil storage tank is through intercommunication oil groove intercommunication, the oil filler point has been seted up to the plain end side of axle sleeve body, the exhaust duct has been seted up to the circle end one side of axle sleeve body.
As an optimal technical scheme of the utility model, the width of intercommunication oil groove and annular oil storage tank is 3 mm.
As an optimized technical scheme of the utility model, the shape of oil filler point is the toper counter bore, and the diameter of oil filler point is 2 mm.
As an optimized technical scheme of the utility model, the width of air discharge duct is 1mm, the degree of depth of air discharge duct is 0.5 mm.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses simple structure is because of adopting annular oil storage tank structure, pack into the back at the step central siphon, just formed comparatively confined environment relatively, the lubricating grease of storage is difficult to run off, can play effectual lubrication action, an oiling mouth has been designed in the side of axle sleeve body, and the tapered counter bore scheme of oiling mouth design, can not only realize supplementing the inside grease of axle sleeve body, the oiling mouth is aimed at better to tapered counter bore design also enables the oil gun mouth, conveniently refuel, the intercommunication processing has been done to three annular oil storage tank in oiling mouth position, when making things convenient for the oiling, lubricating grease can flow to three oil storage tank evenly in, because of the relatively poor air exhaust slot of one has been opened in axle sleeve body round end one side of grease mobility, so that lubricating grease can fully fill whole oil storage tank.
