Embodiment Construction
[0016] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are described below in detail with accompanying drawings.
[0017] combine figure 1 and figure 2 , the present invention mainly includes a non-return inner ring 1 , a non-return roller 3 and a non-return outer ring 4 . Among them, the non-return inner ring 1 is installed on the drive shaft of the hoist, and there are several wedge-shaped grooves on the non-return inner ring 1, and the anti-return roller 3 is installed in the wedge-shaped groove between the non-return inner ring 1 and the non-return outer ring 4. , with non-return retaining ring 6 and shaft retaining ring 2 on both sides to position the non-return roller 3 in the axial direction, and at the same time restrict the non-return roller 3 in the wedge-shaped groove, and the non-return outer ring 4 is welded on the non-return positioning plate 5, there are elongated holes ...

The invention relates to an anti-reversing device for a hoisting machine. The anti-reversing device comprises a reversing-stopping inner ring, a plurality of reversing-stopping rollers and a reversing-stopping outer ring, wherein the reversing-stopping inner ring is arranged inside the reversing-stopping outer ring; an axial mounting hole is formed on the reversing-stopping inner ring; the mounting hole corresponds to a transmission shaft of the hoisting machine; a key slot is formed in the mounting hole; a plurality of wedge slots are formed on the outer wall of the reversing-stopping inner ring; the reversing-stopping rollers are arranged in each wedge slot; the space between the bottoms of the wedge slots and the inner wall of the reversing-stopping outer ring is larger than the diameters of the reversing-stopping rollers; the space between the tops of the wedge slots and the inner wall of the reversing-stopping outer ring is smaller than the diameters of the reversing-stopping rollers; and the wedge slots point at the direction reverse to the rotation of the reversing-stopping inner ring 1. The anti-reversing device has the effect of making equipment unidirectionally operated by using the effective combination of the reversing-stopping inner ring, the reversing-stopping rollers and the reversing-stopping outer ring.
Description
technical field [0001] The invention relates to a device for preventing reverse rotation of a bucket elevator, which belongs to the field of conveying machinery. Background technique [0002] The bucket elevator in the prior art is not equipped with an anti-reversal device. Once the power fails or the equipment fails, when the driving force is lost and the reverse occurs, it will cause damage to the equipment itself and the geared motor, and it will also bring safety to the maintenance personnel. Hidden danger. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned shortcomings, to provide a device for preventing reverse rotation of the bucket elevator, which uses the effective combination of the non-reverse inner ring, the non-reverse roller and the non-reverse outer ring to make the equipment only run in one direction. Effect. [0004] The technical scheme adopted in the present invention is specifically as follows: ...
