Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
A kind of big center is provided in embodiment away from gear reduction unit, including gear-box 1, input shaft 2, output shaft 3, slow is passed
Motor 32 and multiple transmission gears 4, input shaft 2 and output shaft 3 are plugged in inside gear-box 1, and input shaft 2 and output
Axis 3 runs through the front end face of gear-box 1, and multiple gear drives 4 are set to the inside of gear-box 1, and multiple transmission gears 4 are by upper
It is sequentially increased to lower gear radius and from top to bottom successively engages, input gear 21 is arranged on input shaft 2, is covered on output shaft 3
Equipped with output gear 31, the transmission gear 4 positioned at multiple 4 upper ends of transmission gear is engaged with input gear 21, is located at multiple transmissions
The transmission gear 4 of 4 lower end of gear is engaged with output gear 31, and the machine 32 that conducts electricity slowly is fixedly connected with one end of output shaft 3.Work as gear
Speed reducer start to work when, external equipment connect input shaft 2, power is transmitted at input shaft 2, input shaft 2 obtain power it
After begin to rotate, while the power of input is transmitted down.And then, power is transmitted to transmission gear 4, multiple biographies of setting
4 center of moving gear is arranged successively away from ascending, and center obtains powered rotation from input shaft 2 at first away from small transmission gear 4, is turned
Big transmission gear 4 behind is successively driven after dynamic, due to be transmission gear 4 be it is ascending set gradually, can be with
So that the transmission of power is more linear strong, not to the situation for power output deficiency occur, in transmission gear 4 lowermost one
It is a to be meshed with output shaft 3, output shaft 3 is delivered power to, driving output shaft 3 rotates, and thus completes a set of power transmission
Movement, in minimum output shaft 3 by last power transmission to the slow machine 32 that conducts electricity.The middle part of each transmission gear 4, which is run through, to be set
It is equipped with a rotary shaft 41.When transmission gear 4 obtains dynamic rotation, begin to be rotated around rotary shaft 41.Rotary shaft
41 provide fulcrum for rotation.
In order to enable rotary shaft 41 can be rotated swimmingly, further, the both ends of rotary shaft 41 pass through bearing 42 with
