Abstract

The utility model discloses a reduction box for lighthouse lifting. The reduction box for the lighthouse lifting comprises a worm bar, a worm wheel, a box body and an idler wheel, wherein two sides of the worm wheel are respectively and fixedly connected with the box body through a worm wheel bearing, two sides of the worm bar are respectively and fixedly connected with the box body through a worm bar bearing, and the worm bar and the worm wheel are mutually meshed. Two sides of the box body are clamped with the worm wheel bearing through an end cap of the worm wheel, and the other side of the box body is clamped with the worm bar bearing through an end cap of a bearing. The idler wheel is inserted into a worm wheel hole and is fixedly connected with the worm wheel through bolts. The inside of the worm wheel is iron core and the outer ring of the worm wheel is copper ring. Metal cushion blocks are arranged at two sides of the copper ring, and screws are disposed at two sides of the connecting portion between the worm wheel and the box body. The iron cushion blocks and two screws disposed at two sides of the worm wheel inside the reduction box are used to prevent the copper ring from breaking away from the iron core and causing falling of the lighthouse, and therefore the reduction box for the lighthouse lifting is simple in structure, low in cost of implementation, and capable of increasing safety performance of the reduction box.

Description

A kind of beacon promotes uses speed reducer

Technical field

The utility model relates to the speed reducer field, and particularly a kind of beacon promotes uses speed reducer.

Background technique

On the square or the place of needs such as both sides, expressway illumination bigger lighting burner can be set, after lighting burner has been broken, normally adopt Promotion From Within mechanism to carry out the maintenance of lighting burner; Promptly adopt beacon to promote and use speed reducer, have now beacon with speed reducer in lifting process, if run into the impact force of burst; Copper band on the speed reducer worm gear has the possibility that comes off; In a single day copper band comes off, and will cause beacon to lose lifting force and falls, and not only damages beacon; Also bring great inconvenience, also hidden danger.

The model utility content

In order to overcome the defective that above-mentioned existing technology exists, the utility model provides a kind of beacon to promote and uses speed reducer, has prevented that under cost-effective prerequisite copper band from coming off, and stops the possibility that beacon drops, and has improved Safety performance.

To achieve these goals, the technological scheme of the utility model is following:

A kind of beacon promotes and uses speed reducer, comprises worm screw, worm gear, casing, roller, and the worm gear both sides are connected through Worm Bearing and casing respectively; The worm screw both sides are connected through worm bearing and casing respectively, and worm and wheel is meshing with each other, and the casing both sides are through worm gear end cap and Worm Bearing clamping; The casing opposite side is connected through bearing (ball) cover and casing, and roller inserts worm wheel aperture and is connected through screw and worm gear, realizes the axially locating of roller; Worm gear is the worm gear of inner iron core, outer ring copper band, has improved worm gear intensity, and the copper band both sides are provided with backing metal; Prevent that copper band is receiving to break away from iron core under the powerful external force situation; Worm gear and both sides, casing joint are provided with screw, prevent that copper band breaks away from iron core because of split by powerful impulse force, the possibility of avoiding beacon to fall because of speed reducer damages.

Be provided with O type circle between said casing of the utility model and the worm gear end cap, play the effect of oil sealing, prevent leakage of oil between casing and the end cap.

The said bearing of the utility model outside is provided with oil sealing, plays dustproof effect.

Be provided with the hole card between said worm screw one side bearing of the utility model and the oil sealing, to block bearing.

The beneficial effect of the utility model is, utilizes the inner worm gear both sides iron cushion block of speed reducer and two screws to prevent that copper band breaks away from iron core and causes beacon to fall, and is simple in structure, realizes that cost is low, improves the Safety performance of speed reducer.
