Description
Technical field
The present invention relates to winch clutch field, more particularly to a kind of winch clutch with integrated abrasion compensation
And its using method.
Background technology
Winch, with the small-sized crane gear of reel lay winding wire ropes or chain lifting or traction, also known as hoist engine.
Winch is to can be used alone, also can make lifting, build the road and the machinery such as mine hoisting in building block, because of simple to operate, wiring
Amount is big, dislocation is conveniently extensively applied.Mainly apply to building, hydraulic engineering, forestry, mine, harbour etc. material lifting or
Put down and drag.
Mostly thrust between traditional structure this winch movable friction plate and static friction piece is the side being compressed using disk spring
Formula produces, and when needing clutch, spring is pulled open in hydraulic jack oil-feed, release spring pressure, and movable friction plate and static friction piece unclamp.
Because spring pressure sets in initial assembling, but after long-time use, abrasion, kinematics and static friction in friction plate
Gap is produced it is impossible to compensate, pressing force of the spring is gradually reduced, finally due to thrust not, friction plate frictional force is not between piece
Enough to the torque overcoming load to produce, so the phenomenon skidded during winch work easily occurs.Now need to remove whole machine, more
Renewal of facing renewal, adjusts spring pressure, the usage cycles life-span of whole machine is not high, and wastes time and energy.
