Description
Technical field
The utility model relates to a kind of elevator rope pulley bearing arrangement, in particular to a kind of high-speed overload elevator rope pulley bearing
Automatic oil recharging device.
Background technique
The normal speed and payload ratings of high-speed overload elevator are all bigger than conventional elevator, need higher load capacity,
Therefore rope sheave/bearing/axis of this elevator is all bigger than conventional elevator in design.The bearing of conventional elevator generally can be used
6313 type self-lubricating bearings；And high-speed overload elevator needs use 21320 bigger type self aligning roller bearings, the bearing bore diameter
100mm, outer diameter 215mm, need to fill lubricating oil, and the cavity space that axis and rope sheave inner cavity are formed is very big, and when each maintenance needs
A large amount of oil mass is injected, and the oil injected largely rests in internal cavity, does not play the role of lubricating bearing, be easy to cause
The insufficient lubrication of bearing influences its service life.This is that the application needs place improved emphatically.
Utility model content
Technical problem to be solved in the utility model is to provide for a kind of lubricating status for improving bearing, extends the bearing longevity
The automatic oil recharging device of the high-speed overload elevator rope pulley bearing of life.
For the technical problem more than solving, the utility model provides a kind of the automatic of high-speed overload elevator rope pulley bearing
Recharging oil device is pressed into a type chamber part in the space between the inner cavity and bearing of the rope sheave to reduce oil storage space, the type chamber
Part is equipped with a plurality of guide groove for flowing into bearing, and rope sheave and bearing assemble, and bearing is coupled with wheel shaft, and rope sheave high-speed rotation generates
Centrifugal force makes lubricating oil through guide groove water conservancy diversion to bearing, carries out uninterrupted repairing lubrication to bearing.
The embedded SMA actuators of the rope sheave are had backing when being pressed into convenient for type chamber part from two sides at the convex with gradient.
The rope sheave side is equipped with multiple pump nozzles, and multiple pump nozzles are uniformly distributed.
The bearing (ball) cover at the bearing both ends is bolted with rope sheave outer ring.
The bearing (ball) cover is equipped with multiple pump nozzles, carries out the regular repairing lubrication in outside of bearing.
The wheel shaft is optical axis, or is Step Shaft.
Superior effect of the utility model is:
1) inner cavity of the utility model rope sheave increases cavity, reduces oil storage space, reduce because type chamber it is excessive caused by
The loss of lubricating oil, rope sheave generate centrifugal force when rotating, and the lubricating oil in type chamber is moved to two sides, rope sheave structure and is mounted on rope
Component on wheel improves dynamic balance performance when elevator high-speed cruising all using being evenly distributed with；
2) the type chamber part of the utility model is fixed with rope sheave using interference fit or equivalent way, to the balance of rope sheave rotation
Property is without influence；The groove of constant slope, the lubricating oil that storage is added from pump nozzle in groove, because of type chamber part are formed among type chamber part
It is rotated together with rope sheave, lubricating oil is moved since centrifugal force is acted on to type chamber part two sides, and type chamber part two sides are equipped with slanting guiding
Slot, lubricating oil flow to bearing through guide groove, play the role of uninterrupted repairing in Bearing inner；The effective water conservancy diversion lubrication of guide groove
Oil extends bearing life so that the bearing lubrication of rope sheave is uniform when oiling；
3) bearing (ball) cover not only plays the role of being compacted bearing, but also plays the role of sealing cord wheel-type chamber, prevents outside lubricating oil
It overflows, multiple axially uniformly distributed pump nozzles is set on bearing (ball) cover, in the regular repairing of Bearing outer.
