Abstract
The present invention relates to a kind of anti-dropout pulley.Including wheel carrier, the wheel carrier is c-type structure, pulley is provided with the wheel carrier, bearing is provided with the centre bore of the pulley, the bearing holder (housing, cover) is on an axle, the axle left end is fixedly mounted on the side plate of wheel carrier, shrouding is provided with the wheel carrier, the shrouding is located on the right side of pulley, and the shrouding is parallel with the side plate of wheel carrier, the axle right-hand member is arranged on shrouding, and the distance between the pulley upper and lower ends and wheel carrier upper and lower ends plate inner surface are less than the radius of rope.The present invention is simple in construction, operates easy for installation, stable and reliable operation, by the way that the distance between pulley upper and lower ends and wheel carrier upper and lower ends plate inner surface to be designed as to the radius less than rope, effectively prevents rope from being split away off from pulley, ensure that normal work uses.
Description
Technical field
The present invention relates to a kind of pulley, more particularly to a kind of anti-dropout pulley.
Background technology
Pulley be for lifting heavy and can labour-saving it is simple and mechanical, be that a periphery has groove, be capable of the steamboat of pivoting, by can be around the fluted disk of central axis and across disk flexible cable formed can around central shaft rotate it is simple and mechanical.Using quite varied, but in use, rope is easily skidded off and wound with pulley present pulley out of pulley groove, cause pulley can not normal work, bring inconvenience to normal use, have impact on operating efficiency.
The content of the invention
For drawbacks described above, it is an object of the invention to provide a kind of simple in construction, easy for installation, the stable and reliable operation of operation, a kind of anti-dropout pulley for effectively preventing rope from being come off from pulley.
It is for this technical solution adopted in the present invention：
Including wheel carrier, the wheel carrier is c-type structure, pulley is provided with the wheel carrier, bearing is provided with the centre bore of the pulley, the bearing holder (housing, cover) is on an axle, the axle left end is fixedly mounted on the side plate of wheel carrier, shrouding is provided with the wheel carrier, the shrouding is located on the right side of pulley, and the shrouding is parallel with the side plate of wheel carrier, the axle right-hand member is arranged on shrouding, and the distance between the pulley upper and lower ends and wheel carrier upper and lower ends plate inner surface are less than the radius of rope.
Further, the positioning sleeve being enclosed on axle is provided between the pulley and wheel carrier, pulley and shrouding.
Further, the locking nut being enclosed on axle is provided with the right side of the shrouding, the right-hand member of the axle is located in wheel carrier.
Further, the right-hand member of the upper and lower ends plate of the wheel carrier is respectively equipped with installation foot.
It is an advantage of the invention that:
The present invention is simple in construction, operates easy for installation, stable and reliable operation, by the way that the distance between pulley upper and lower ends and wheel carrier upper and lower ends plate inner surface to be designed as to the radius less than rope, effectively prevents rope from being split away off from pulley, ensure that normal work uses.
