Abstract
The utility model relates to a speed reducer, in particular to a worm wheel and worm speed reducer with a worm wheel firming mechanism. The worm wheel and worm speed reducer with a worm wheel firming mechanism comprises a box body, wherein a unidirectional and bidirectional output shaft is inserted into the box body; a worm wheel is sleeved on the unidirectional and bidirectional output shaft and meshed with a worm in the box body; the unidirectional and bidirectional output shaft is fixed with the worm wheel through a flat key; two ends of the worm wheel are fixed with the box body through bearings respectively; an output flange is arranged on the side wall of the left end of the box body; and the unidirectional and bidirectional output shaft is arranged in the output flange. The worm wheel and worm speed reducer with a worm wheel firming mechanism has a simple structure, high mounting precision and a good using effect.
Description
Technical field
The utility model patent relates to a kind of speed reducer, relates in particular to a kind of worm-gear speed reducer with the firm mechanism of worm gear.
Background technique
The speed reducer of present existing technology, complex structure, and also operational effect is relatively poor relatively.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the existing technology, provides a kind of simple in structure, and the worm-gear speed reducer of the outstanding firm mechanism of band worm gear of using effect.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of worm-gear speed reducer with the firm mechanism of worm gear; Comprise casing, be plugged with the single-direction and dual-direction output shaft in the described casing, be with worm gear on the described single-direction and dual-direction output shaft; Described worm gear is meshed with worm screw in the casing; Described single-direction and dual-direction output shaft and worm gear fix through flat key, and the two ends of described worm gear fix through bearing and casing respectively, and the left end sidewall of described casing is provided with output flange; Described single-direction and dual-direction output shaft is located in the output flange; The two ends of described worm gear are mutually close with casing through oil sealing respectively, and the output terminal of described single-direction and dual-direction output shaft is provided with fixedly flat key, and described worm gear and single-direction and dual-direction output shaft are fixed through the flat key of pair of spaced.
Therefore, a kind of worm-gear speed reducer of the utility model with the firm mechanism of worm gear, simple in structure, installation precision is high, and using effect is good.
Description of drawings
Fig. 1 is the structural representation of the utility model.
