Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0016] Such as Figure 1~3 As shown, the winch of the present invention includes a support 1 on which a reel 3, a prime mover 2, a speed reducer 4, a first clutch 6 and a braking device 8 are arranged. The reel 3 and the bracket 1 are engaged in rotation, the output part of the prime mover 2 is connected with the input part of the reducer 4 , and the output part of the reducer 4 is connected with the reel 3 . The first clutch 6 includes an outer shaft 61 and an inner shaft 63 , a clutch plate 62 is provided between the outer shaft 61 and the inner shaft 63 , and the inner shaft 63 is connected with the braking device 8 . The reducer 4 is a shell-rotating planetary reducer 4, the output part of the shell-rotating planetary reducer 4 is its output shell, the reducer 4 is located in the reel 3, and the output shell of the reducer 4 is connected to the reel 3 T...

The invention relates to a lifting mechanism, in particular to a winch. The winch comprises a support, a coiling block, a prime motor, a speed reducer, a first clutch and a brake device are arranged on the support, the coiling block and the support are in rotation fit, the output part of the prime motor is connected with the input part of the speed reducer, the output part of the speed reducer isconnected with the coiling block, the first clutch comprises an outer shaft and an inner shaft, a clutch piece is arranged between the outer shaft and the inner shaft, and the inner shaft is connectedwith the brake device. The winch has the advantages that the speed reducer is a shell rotation type planetary reducer, the output part of the shell rotation type planetary reducer is an output shellthereof, the speed reducer is located in the coiling block, the output shell of the speed reducer is connected with the coiling block, a shell of the speed reducer is coaxially and fixedly provided with an output shaft, the first clutch and the speed reducer are coaxially arranged, the output shaft and the outer shaft of the first clutch are fixed concentrically, parts of the winch are few, the structure is compact, size is small, weight is small, and the winch can be conveniently used on a ship.
Description
technical field [0001] The invention relates to a hoisting mechanism, in particular to a winch which is matched with the hanger of a marine lifeboat or rescue boat and is used to realize the normal lifting and lowering functions of the lifeboat or rescue boat. Background technique [0002] A traditional lifeboat or rescue boat winch consists of a frame with a drum, prime mover, speed reducer, clutch and brake. The reel and the bracket are rotated and matched, the reducer is a multi-stage transmission reduction box, the output part of the prime mover is connected with the input part of the multi-stage transmission reduction box, and the output part of the multi-stage transmission reduction box is connected to the The reels are connected. The first clutch includes an outer shaft and an inner shaft. There is a clutch plate between the outer shaft and the inner shaft. The inner shaft is connected to the braking device, and the outer shaft is connected to the multi-stage transmi...
