Abstract
The utility model discloses a high-efficiency transmission worm reducer which comprises a cabinet, a worm gear, a worm, an output shaft and an end cover, wherein the end cover is fixed on the cabinet; the worm gear is mounted on the output shaft; the output shaft is mounted on the cabinet through a bearing; the worm gear is meshed with teeth on the worm; the front end part of a thread of the worm is provided with three meshing inlets matched with the worm gear; and the meshing inlets are evenly distributed on the outer surface of the worm. Since the end part of the thread of the worm in the high-efficiency transmission worm reducer is provided with the three meshing inlets matched with the worm gear, the transmission efficiency of the worm and the worm gear is improved in the transmission process. Thus, the high-efficiency transmission worm reducer has the advantages of compact structure and high transmission efficiency of the whole reducer.
Description
Technical field
The utility model relates to a kind of speed reducer, relates in particular to the high worm decelerating machine of a kind of transmission efficiency.
Background technique
Speed reducer is that a kind of power is passed on mechanism, utilizes the velocity transducer of gear, the winding number of motor (motor) is decelerated to desired winding number, and obtain the mechanism of big torque.Be used for the mechanism of transferring power and motion at present, the application area of speed reducer is quite extensive.Almost in the transmission system of various machinery, can see its trace.
Speed reducer can be divided into gear reducer, worm reducer and plane table thermoconductivity meter according to the transmission type; The main feature of worm-gear speed reducer is to have reverse auto-lock function, and bigger reduction speed ratio can be arranged, and traditional worm-gear speed reducer exists volume bigger, the shortcoming that transmission efficiency is not high.
The model utility content
The purpose of the utility model is to provide a kind of worm decelerating machine of efficient transmission, and it has compact structure and the high characteristics of transmission efficiency, has effectively solved the problem that worm decelerating machine exists in the existing technology.
The purpose of the utility model is to realize through following technological scheme:
A kind of worm decelerating machine of efficient transmission; It comprises casing, worm gear, worm screw, output shaft and end cap; Said end cap is fixed on the casing, said output shaft worm gear is installed and through Bearing Installation on casing, said worm gear is meshed with tooth on the worm screw; Wherein, the thread head of said worm screw cooperates worm gear to offer at least two engagement inlets.
Especially, the number of said engagement inlet is set to three.
Especially, said engagement inlet is distributed on the outer surface of worm screw.
Especially, said end cap is fixed on the casing through fixing bolt.
The beneficial effect of the utility model does; The worm decelerating machine of the said efficient transmission compared with prior art thread head of worm screw cooperates worm gear to offer three engagement inlets; In transmission process; Improved the transmission efficiency of worm and worm wheel, had compact structure, the high advantage of the whole transmission efficiency of speed reducer.
Description of drawings
Fig. 1 is the sectional drawing of the worm decelerating machine of the efficient transmission that provides of the utility model embodiment 1.
Embodiment
Further specify the technological scheme of the utility model below in conjunction with accompanying drawing and through embodiment.
See also shown in Figure 1ly, Fig. 1 is the sectional drawing of the worm decelerating machine of the efficient transmission that provides of the utility model embodiment 1.
In the present embodiment, a kind of worm decelerating machine of efficient transmission comprises casing 1, passes through fixedly end cap 2 of fixing bolt 8 on the said casing 1; One end machined grooves of said casing 1, corresponding to mounting holes on the end cap 2, an end of output shaft 3 is arranged in the groove through bearing 4; The other end passes mounting hole and stretches out outside the end cap 2, between said end cap 2 and the output shaft 3 bearing 4 is installed also, is connected with worm gear 7 through key 5 on the said output shaft 3; Cooperate worm gear 7 to be provided with worm screw 6; Tooth on the said worm screw 6 is meshed with worm gear 7, and the thread head of said worm screw 6 cooperates worm gear 7 to offer three engagement inlets, and said engagement inlet is distributed on the outer surface of worm screw 6.
The worm screw 6 of the worm decelerating machine of said efficient transmission is connected with the rotor shaft of motor; During the rotor shaft rotation, drive worm gear 7 and worm screw 6 transmissions, because of the thread head on the worm screw 6 offers three engagement inlets; Improved the transmission efficiency of worm gear 7 and worm screw 6; Thereby improved the transmission efficiency of speed reducer on the whole, reasonable structural arrangement is compact simultaneously, and volume is little.
