Abstract

The invention relates to a winch. The winch has a structure of a built-in motor and a planetary speed-change mechanism, and consists of a bracket, a motor, a drum, a speed changer and a bearing, wherein the motor is arranged in an inner cavity of the drum and is connected with the speed changer through a transmission shaft; the speed changer is connected with the drum; and the motor, the drum and the speed changer are arranged and fixed on the bracket through the bearing. By the winch, an auxiliary crane which has a small structure, is convenient to operate and use, and is safe and reliable can be used on various ships; and the winch with a planetary transmission speed reduction mechanism has high work reliability and a light structure, is convenient to install and use, and is safe and reliable.

Description

A kind of winch

Technical field the present invention relates to a kind of winch, and the winch that uses on especially a kind of loop wheel machine belongs to the mechanical equipment field.

The auxiliary small-sized loop wheel machine that is used to lift the productive life goods and materials that background technology is used on boats and ships at present, easy to use and be used widely with it, but matching used winch is a serving formula transmission device on auxiliary small-sized loop wheel machine at present, the winch of this structure is because its structure heaviness, also make and assist small-sized loop wheel machine structure heaviness, owing to structural relation, serving formula transmission device also can't guarantee the reliability that auxiliary small-sized loop wheel machine uses on boats and ships simultaneously.

Summary of the invention the invention provides a kind of a kind of winch of novelty, adopts planetary mechanism transmission braking technique, and not only structure had been lightly but also have a purpose of higher functional reliability to realize auxiliary small-sized loop wheel machine.

Technical scheme of the present invention:

A kind of winch, described winch is built-in motor and planet speed change mechanism structure, constituted by support, motor, reel and change-speed box and bearing, motor is arranged in the inner chamber of reel, motor is connected with change-speed box by transmission shaft, change-speed box is connected with reel, and motor, reel, change-speed box are fixed on the support by bearing installation.

Change-speed box is a planet speed change mechanism, is arranged at a side position of winch.

Owing to adopted a kind of winch of the present invention, make all kinds of boats and ships can both use both structure miniaturizations, safe and reliable again auxiliary loop wheel machine easy for operation, and the winch functional reliability height of planetary transmission speed reduction gearing, winch structure of the present invention is light and handy, easy to install, safe and reliable.

The specific embodiment

As shown in Figure 1.

A kind of winch, described winch is built-in motor and planet speed change mechanism structure, constituted by support 1, motor 2, reel 3 and change-speed box 4 and bearing, motor 2 is arranged in the inner chamber of reel 3, motor 2 is connected with change-speed box 4 by transmission shaft, change-speed box 4 is connected with reel 3, and motor 2, reel 3, change-speed box 4 are fixed on the support 1 by bearing installation.

Change-speed box 4 is a planet speed change mechanism, is arranged at a side position of winch.

The loop wheel machine tube is installed on the chassis, rotating mechanism is installed on the loop wheel machine tube, main shaft is installed in loop wheel machine tube and the rotating mechanism, rotary reducer is connected with the tooth axle with motor, after the three is linked and packed rotary reducer is installed in the loop wheel machine, promptly be installed in loop wheel machine tube and the rotating mechanism, then platform is installed on the rotating mechanism, winch and arm are installed on the platform, lifting rope one end is connected with winch, the lifting rope passes the pulley on the arm, and the lifting rope other end is connected with suspender.

Give electrical power, then motor rotates by driving the tooth axle after the rotary reducer speed change, and the inner gear in the tooth axle driven rotary mechanism rotates, and inner gear driven rotary mechanism rotates, thereby drive platform is that rotary middle spindle rotates with the main shaft, thereby realizes the horizontal rotation motion of arm.

Give the electrical power in the winch, then motor rotates, and motor drives reel by change-speed box and rotates, thereby drives the folding and unfolding of lifting rope, thereby realizes the purpose of lifting and arrangement of goods.

This loop wheel machine can be used as the auxiliary loop wheel machine of big-and-middle-sized boats and ships, also can be used as the goods loop wheel machine of spitkit, can also be as the land loop wheel machine.
