Description
[technical field]
The utility model relates to a kind of improvement invention of gear reducer.
[background technique]
Retarder plays coupling rotating speed and transmitting torque between prime mover and working machine or actuator, be a kind of transmission device of independent sealing, uses very extensive in the modern machine.Wherein gear reducer is to utilize gear transmissions at different levels to reach the purpose of reduction of speed and transmitting torque; That gear reducer has is simple in structure, transmitting torque is big, transmission efficiency is high, the cost performance advantages of higher obtains using the most widely; But the deficiency of gear reducer is: velocity ratio can not be very big; If the realization big speed ratio, the gear transmission progression of gear reducer will be a lot, and every grade of gear transmission all will have corresponding transmission shaft; The profile of gear reducer will be very big like this, and can not be applicable to the workplace that installing space is had strict demand.
[summary of the invention]
To the deficiency that existing technology exists, the purpose of the utility model aims to provide the gear reducer that a kind of compact structure can be realized big speed ratio.
The utility model takes following technological scheme to accomplish:
A kind of gear reducer comprises casing, gear and transmission shaft, it is characterized in that: transmission shaft comprises transmission shaft A, transmission shaft B and transmission shaft C, and transmission shaft A and transmission shaft B turn round setting in casing; Transmission shaft A is provided with gear a, gear b, gear c and gear d, and gear a and gear b fixedly mount on transmission shaft A, and gear c and gear d interfix, and gear c that interfixes and gear d turn round setting on transmission shaft A; Transmission shaft B is provided with gear e, gear f, gear g and gear h, and gear g and gear h fixedly mount on transmission shaft B, and gear e and gear f interfix, and gear e that interfixes and gear f turn round setting on transmission shaft B; Transmission shaft C is provided with gear i; Gear a and input gear engagement, gear b and gear e engagement, gear c and gear f engagement, gear d and gear g engagement, gear h and gear i engagement, gear i and output gear engagement.
After adopting technique scheme; Realized the tertiary gear gearing down between transmission shaft A and the transmission shaft B,, realize that the tertiary gear gearing down need could accomplish through four transmission shafts if adopt existing technology; Thus; The utility model compared with prior art, not only compact structure but also can realize big speed ratio is specially adapted to installing space is had the workplace of strict demand.Though the utility model technological scheme is simple, is skillfully constructed, played beyond thought technique effect, compared with prior art, have substantive distinguishing features and progress.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of the utility model
[embodiment]
Come the utility model is explained in detail and explains through specific embodiment below:
With reference to Fig. 1, the gear reducer of the utility model comprises casing 1, gear and transmission shaft, and transmission shaft comprises transmission shaft A, transmission shaft B and transmission shaft C, and transmission shaft A and transmission shaft B turn round setting through bearing in casing 1; Transmission shaft A is provided with gear a, gear b, gear c and gear d, and gear a and gear b fixedly mount on transmission shaft A through flat key, and gear c and gear d interfix, and gear c that interfixes and gear d turn round setting through bearing on transmission shaft A; Transmission shaft B is provided with gear e, gear f, gear g and gear h, and gear g and gear h fixedly mount on transmission shaft B, and gear e and gear f interfix, and gear e that interfixes and gear f turn round setting through sliding sleeve 4 on transmission shaft B; Transmission shaft C is provided with gear i, and gear i turns round setting through bearing on transmission shaft C; Gear a and 2 engagements of input gear, input gear 2 is fixed on the lock sleeve 3, gear b and gear e engagement; Gear c and gear f engagement, gear d and gear g engagement, gear h and gear i engagement; Gear i and output gear 5 engagements, output gear 5 is fixed on the output shaft 6.
The utility model is work like this: input gear 2 is fixed on motor shaft or the input shaft through lock sleeve 3, input gear 2 driving gear a, and velocity ratio is 3.5; Gear b driving gear e, velocity ratio is 7, gear f driving gear c; Velocity ratio is 3.5, gear d driving gear g, and velocity ratio is 3.1; Gear f is through gear i transmission output gear 5, and velocity ratio is 1, and the velocity ratio of a whole like this retarder can reach 266.In above-mentioned gear transmission process, total level Four gearing down, (the gear b driving gear e of tertiary gear gearing down wherein; Gear f driving gear c; Gear d driving gear g) all between transmission shaft A and transmission shaft B, accomplishes, promptly realized the tertiary gear gearing down between transmission shaft A and the transmission shaft B, if adopt existing technology; Realize that the tertiary gear gearing down need could accomplish through four transmission shafts; And can only reach about 70-80 with the velocity ratio of the existing technology gear reducer of the utility model same size, identical appearance size, thus, the utility model is compared with prior art; Not only compact structure but also can realize big speed ratio is specially adapted to installing space is had the workplace of strict demand.
