Abstract
The utility model relates to a shifting fork three gear speed reducer. The shifting fork three gear speed reducer comprises a box body, and an input shaft which is connected with an output end of a motor is arranged on the box body. The shifting fork three gear speed reducer is characterized in that a high-speed gear which rotates coaxially is arranged on the input shaft, the high-speed gear is transmitted with a middle big gear in a meshed rotary mode, the middle gear coaxially rotates with a middle shaft in a fixed mode, a middle small gear is further coaxially arranged on the middle shaft, and the middle small gear acts with a low-speed differential gear on the output shaft and a low-speed gear on the output shaft through a shifting fork mechanism to drive an output shaft to rotate. According to the shifting fork three gear speed reducer, two kinds of speed change of a single speed reducer in structure can be achieved, a shifting fork shaft is parallel to the output shaft, the handle of the shifting fork shaft moves axially, operation is on the reverse side of the output shaft, the structure is simple, and the demands of installation and operation in special occasions are met.
Description
Technical field
The utility model belongs to the speed reducer field, is specifically related to a kind of shift fork three retaining speed reducers.
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.For the mechanism of transferring power and motion, the application area of speed reducer is quite extensive at present.Almost in the transmission system of various machinery, can see its trace, from boats and ships, automobile, the locomotive of the traffic tool, heavy facility for building, the machining machine and tool that mechanical industry is used and automated production equipment, common household electrical appliances in the daily life, clock and watch etc.It uses the transmission work from big power, and to little load, accurate angle transmission can be seen the application of speed reducer, and on commercial Application, speed reducer has deceleration and increases the torque function.Therefore be widely used in the conversion equipment of speed and moment of torsion, normally adopt complicated gear graduation to make up to realize the speed change of many retainings for common gear reduction unit.
Summary of the invention
The utility model then provides a kind of shift fork three retaining speed reducers in order to solve the technical problem of mentioning in the background technique.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of shift fork three retaining speed reducers, comprise casing, described casing is provided with the input shaft that is connected with motor output end, it is characterized in that: described input shaft is provided with the high gear of coaxial rotation, described high gear and a gear mesh broad in the middle rotate transmission, described gear broad in the middle and the coaxial fixedly rotation of jack shaft, the coaxial intermediate speed pinion that is provided with also on the described jack shaft, described intermediate speed pinion drives output shaft by the low speed differential gear on shifting fork mechanism and the output shaft and low speed gear effect and rotates.
Described shifting fork mechanism comprises declutch shift shaft and shift fork, and described declutch shift shaft moves axially, and drives shift fork and stirs low speed differential gear and intermediate speed pinion engagement, is provided with three locating slots on the declutch shift shaft axle of described shifting fork mechanism successively.
Described low speed differential gear is slidingly mounted on the output shaft, the interlock mutually of low speed differential gear and low speed gear.
