Abstract

The utility model discloses a double-transmission reduction box which comprises an input gear shaft, a transmission gear, a transmission gear shaft and an output shaft gear, wherein the transmission gear comprises an upper transmission I shaft gear, an upper transmission II shaft gear, a lower transmission I shaft gear and a lower transmission II shaft gear; and the transmission gear shaft comprises an upper transmission I shaft gear shaft, an upper transmission II shaft gear shaft, a lower transmission I shaft gear shaft and a lower transmission II shaft gear shaft. In the double-transmission reduction box, an upper transmission chain and a lower transmission chair transfer power in a shunting mode, power entering the reduction box via the input shaft is evenly distributed onto the upper transmission chain and the lower transmission chair, and therefore the double-transmission reduction box has the advantages of more excellent performance, large load bearing capability, long service life and the like, is stable to operate and is safe and reliable.

Description

A kind of pair of transmission speed reducer
Technical field
The utility model relates to a kind of mechanical transmission, particularly relates to a kind of pair of transmission speed reducer.
Background technique
Speed reducer is that a kind of power is passed on mechanism, utilizes gear to realize the conversion of speed, 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; From boats and ships, automobile, the locomotive of the traffic tool, heavy facility for building, machining machine and tool that mechanical industry is used and automated production equipment; Common household electrical appliances in the daily life, clock and watch or the like.From the transmission work of big power, to little load, accurate angle transmission can see 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.
At present, the speed reducer on the market is that patrilineal line of descent with only one son in each generation is moving mostly, and it exists galloping, bearing capacity than the end, shortcoming such as Safety performance is lower and working life is short.
The model utility content
The technical problem that the utility model solved is to provide a kind of pair of transmission speed reducer, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technological scheme to realize:
A kind of pair of transmission speed reducer; Comprise input gear shaft, driving gear, driving gearshaft and output shaft gear; Said driving gear comprises transmission I shaftgear, goes up transmission II shaftgear, underdrive I shaftgear and underdrive II shaftgear, and said driving gearshaft comprises transmission I shaftgear axle, goes up transmission II shaftgear axle, underdrive I shaftgear axle and underdrive II shaftgear axle; Said input gear shaft is a herringbone gear shaft, respectively with last transmission I shaftgear and the engagement of underdrive I shaftgear; Last transmission I shaftgear is installed on the transmission I shaftgear axle, last transmission I shaftgear axle and the engagement of last transmission II shaftgear, and the said transmission II shaftgear of going up is installed on the transmission II shaftgear axle; Said underdrive I shaftgear is installed on the underdrive I shaftgear axle, underdrive I shaftgear axle and the engagement of underdrive II shaftgear, and underdrive II shaftgear is installed on the underdrive II shaftgear axle; The said transmission II shaftgear axle and underdrive II shaftgear axle while and output shaft gear gone up meshes.
The said transmission II shaftgear of going up is a split-type structural, is connected carry-over moment through pin or interference etc. between wheel hub and gear ring.
Beneficial effect:
The utility model is owing to adopt two Transmitted chains shunting transferring power up and down; To be evenly distributed to through the power that the input gear shaft gets into speed reducer up and down on two Transmitted chainss; Make the utility model usability more excellent, have steady, the advantages such as bearing capacity is high, safe and reliable, long service life of running.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
A kind of pair of transmission speed reducer; Comprise input gear shaft 1, driving gear, driving gearshaft and output shaft gear; Said driving gear comprises transmission I shaftgear 4, goes up transmission II shaftgear 8, underdrive I shaftgear 5 and underdrive II shaftgear 9, and said driving gearshaft comprises transmission I shaftgear axle 2, goes up transmission II shaftgear axle 6, underdrive I shaftgear axle 3 and underdrive II shaftgear axle 7; Said input gear shaft 1 is a herringbone gear shaft, respectively with last transmission I shaftgear 4 and 5 engagements of underdrive I shaftgear; Last transmission I shaftgear 4 is installed on the transmission I shaftgear axle 2, last transmission I shaftgear axle 2 and last transmission II shaftgear 8 engagements, and the said transmission II shaftgear 8 of going up is installed on the transmission II shaftgear axle 6; Said underdrive I shaftgear 5 is installed on the underdrive I shaftgear axle 3, underdrive I shaftgear axle 3 and 9 engagements of underdrive II shaftgear, and underdrive II shaftgear 9 is installed on the underdrive II shaftgear axle 7; The said transmission II shaftgear axle 6 of going up meshed with 7 whiles of underdrive II shaftgear axle and output shaft gear 10.
The said transmission II shaftgear 8 of going up is a split-type structural, is connected carry-over moment through pin or interference etc. between wheel hub and gear ring.
The utility model will be imported gear shaft 1 and be placed in parallel in the same plane with output shaft gear 10, and driving gearshaft (2,3,6,7) is symmetrically distributed in this both sides, plane, and is parallel to input shaft.Driving gear (4,5,8,9) and driving gearshaft (2,3,6,7) form up and down two Transmitted chainss together, will be evenly distributed to through the power that the input gear shaft gets into speed reducer up and down on two Transmitted chainss, make the speed reducer more compact structure, and the load of bearing is bigger.
Said input gear shaft is a herringbone gear shaft, and the profile of tooth of all the other gears, tooth axle is the monocline tooth; The said transmission II shaftgear 8 of going up is a split-type structural, is connected carry-over moment through pin or interference etc. between wheel hub and gear ring, and split-type structural is used for regulating the machining error that assembly process exists.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
