Abstract
The utility model relates to a reducer casing seal structure which belongs to the speed reducer field, particularly a sealing structure of an elevator reducer casing. The utility model is composed of a worm wheel shaft, a bearing, bearing end cap, an oil return ring, an end cap and a shaft sleeve. The bearing is installed on the bearing end cap, an oil return hole is arranged on the bearing end cap, the oil return ring is installed on the worm wheel shaft, the oil return hole of the bearing end cap is provided with an eccentric groove, an oil return pool is formed at the oil return hole of the bearing end cap, and the oil return ring is a labyrinth shape. The utility model has the advantages that the simple structure and the high reliability are realized, the phenomenon of oil seepage or oil leakage is fundamentally solved, and the easy repair and the easy maintenance of a drawing machine of an elevator are realized. The utility model can be widely used for the anti-oil seepage structure or anti-oil leakage of various reducer casings and revolving shafts.
Description
The utility model speed reducer sealing configuration belongs to the speed reducer field, particularly relates to a kind of sealing configuration of elevator gear reducer box.
Tractor worm-wheel shaft bearing seal structure adopts outside framework oil seal and axle pad cover, outside framework oil seal cylindrical and the stationary fit of bearing (ball) cover hole, in circle with press fit over axle pad on the worm-wheel shaft overlap between for movingly, because rubber is aging, cause tractor to use a period of time rear worm wheel shaft sealing place oil impregnate or oil leakage phenomenon to occur, need to change outside framework oil seal,, increase maintenance simultaneously user's inconvenience.
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of mechanical labyrinth sealing principle of utilizing is provided, and stops the structure of the outside seepage of lubricant oil, solves the outside framework oil seal ageing of rubber and causes tractor oil impregnate or oil leakage phenomenon to occur.
The purpose of this utility model reaches by following measure, it is to utilize mechanical labyrinth sealing principle, makes lubricant oil flow directly into the oil return pond, and it is by worm-wheel shaft, bearing, bearing (ball) cover, back oil ring, end cap, axle sleeve is formed, Bearing Installation is on bearing (ball) cover, and bearing housing has spill port on bearing (ball) cover on worm-wheel shaft, back oil ring is installed on the worm-wheel shaft, axle sleeve is enclosed within on the worm-wheel shaft, and end cap is installed on the bearing (ball) cover, and end cap is provided with seal ring, there is an eccentric grove at spill port place at bearing (ball) cover, eccentric grove forms the oil return pond at the spill port place of bearing (ball) cover, and back oil ring is labyrinth-like, and end cap and seal ring play end face seal to bearing (ball) cover, lubricant oil is under the effect of the labyrinth on the back oil ring, flow directly into the oil return pond, flow back to, prevent oil impregnate or oil leakage phenomenon from spill port.
End cap is provided with the O RunddichtringO, and axle sleeve and O RunddichtringO stop micro lubricating oil along the outside seepage of worm-wheel shaft.
The utility model is simple in structure, and the reliability height has fundamentally solved oil impregnate or oil leakage phenomenon, brings convenience for the care and maintenance of elevator tractor, can be widely used in various deceleration box and turning axle seepage-proof oil or leakage of oil structure.
Accompanying drawing 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
As accompanying drawing 1, shown in the accompanying drawing 2, the utility model is by worm-wheel shaft 2, bearing 8, bearing (ball) cover 7, back oil ring 1, end cap 5, axle sleeve 4 is formed, and Bearing Installation is at bearing (ball) cover, bearing housing is on worm-wheel shaft, spill port 10 is arranged on bearing (ball) cover, and back oil ring is installed on the worm-wheel shaft, and axle sleeve is enclosed within on the worm-wheel shaft, end cap is installed on the bearing (ball) cover, end cap is provided with seal ring 3 and 6, at the spill port place of bearing (ball) cover one eccentric grove 9 is arranged, and forms the oil return pond at the spill port place of bearing (ball) cover, back oil ring is labyrinth-like, end cap and seal ring play end face seal to bearing (ball) cover, and lubricant oil flows directly into the oil return pond under the effect of the labyrinth on the back oil ring, flow back to from spill port, prevent oil impregnate or oil leakage phenomenon, end cap is provided with the O RunddichtringO, and axle sleeve and O RunddichtringO stop micro lubricating oil along the outside seepage of worm-wheel shaft.
