Abstract
The invention relates to an expanded gear reducer transmitted in a closed loop mode, comprising input shafts, transmission shafts, output shafts and gears, wherein the gears on the input shafts drive the transmission shaft to rotate respectively by the gears of the transmission shafts, the transmission shafts meshed with the gears which drives the output shafts to rotate by the gears, and the output shafts are driven to rotate sequentially by meshing transmission between the gears. The expanded gear reducer is characterized in that teeth on the front row and rear row of the input shafts are combined into one row to be meshed, and the input shaft transmission shaft and the input shaft are meshed by gears on the shafts to be in closes-loop transmission. The invention has the beneficial effects that each pair of meshed gears only transmit half of whole load, the input shafts and the output shafts only bear half of whole load, and the transmission shafts only bear half of whole load, thus compared with other reducers transmitting the same power, the expanded gear reducer has the advantages that the shaft neck size can be reduced and the width of a box body is greatly reduced, which not only saves used space but also saves manufacture materials.
Description
Technical field
The invention belongs to retarder, relate in particular to a kind of expansion gear reducer of closed loop transmission.
Background technique
The characteristics of gear reducer are efficient and reliability height, long working life, and easy maintenance, thereby be widely used.And the gear reducer of expansion is simple in structure most widely used a kind of.But because its gear is asymmetric with respect to bearing position, when axle produced the bending distortion, load is skewness on the facewidth.Therefore higher for the rigidity requirement of axle.Retarder with seven outputs of a single shaft input is an example.Fig. 5-7 is the structural representation of an expansion retarder, and Fig. 5 shows the radially direct of gear, and M-M sectional view and N-N sectional view show the axial distribution of gear.Axle A is an input shaft, axle B, and axle C is a transmission shaft, axle 1,2,3,4,5,6,7 is an output shaft.Motor drives axle A rotates during retarder work, and gear A drives axle B by gear B and gear C respectively and axle C rotates.The left side: axle B passes through gear B
1Drive axle 3 rotations with the engagement of gear 3, axle 3 rotates by gear 3 and gear 2 engagement drive axles 2, and axle 2 drives axle 1 by gear 2 and gear 1 engagement and rotates; The right side: axle C passes through gear C
1Drive axle 4 with the engagement of gear 4 and rotate, axle 4 drives axle 5 by gear 4 with gear 5 engagements and rotates, and axle 5 drives axle 6 by gear 5 with gear 6 engagements and rotates, and axle 6 drives axle 7 by gear 6 with gear 7 engagements and rotates.Be not difficult to find out that when axle produced the bending distortion, load is skewness on the facewidth.In the actual design, in order to strengthen the rigidity of axle, then will add large-diameter, so the casing width of retarder is strengthened, usage space increases, and causes the waste of material.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, a kind of expansion gear reducer of closed loop transmission is provided, can make every pair of meshed gears only transmit half of whole load, input shaft and output shaft only bear half of whole load, and transmission shaft only is subjected to half of whole load.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of expansion gear reducer of closed loop transmission, comprise input shaft, transmission shaft and output shaft and gear, gear on the input shaft rotates by the gear driven transmission shaft of transmission shaft respectively, transmission shaft is by gear and the gear engagement that drives the output shaft rotation, output shaft drives output shaft by the engagement driving between gear successively and rotates, it is characterized in that: the meshing Cheng Chengyi row engagement on the two row's input shafts of described front and back, input shaft transmission shaft and output shaft cog to mesh by axle and are the closed loop transmission.
Described input shaft cogs and is made as the separated type double helical spurgear.
Beneficial effect: can make every pair of meshed gears only transmit half of whole load, input shaft and output shaft only bear half of whole load, transmission shaft only is subjected to half of whole load, so compare with other retarders that transmit same power, journal size can dwindle, the width of casing has been diminished a lot, not only can save usage space, also save the material of making.

Embodiment
Below in conjunction with preferred embodiment, to details are as follows according to embodiment provided by the invention: see accompanying drawing 1 for details, a kind of expansion gear reducer of closed loop transmission, comprise input shaft A, transmission shaft B, C and output shaft 1,2,3,4,5,6,7 and gear 8, gear on the input shaft rotates by the gear driven transmission shaft of transmission shaft respectively, transmission shaft is by gear and the gear engagement that drives the output shaft rotation, output shaft drives output shaft by the engagement driving between gear successively and rotates, meshing Cheng Chengyi row engagement on the two row's input shafts of described front and back, input shaft transmission shaft and output shaft cog to mesh by axle and are the closed loop transmission.Described input shaft cogs and is made as the separated type double helical spurgear.
Working principle:
As shown in Figure 3, suppose that input shaft is to rotate counterclockwise, axle A meshes the downward tangential force to axle B by gear 8-A and gear 8-B, axle B meshes to axle 3 tangential force left by gear B 1 and gear 8-3, axle 3 meshes to axle 4 to upper right tangential force by gear 8-3 and gear 8-4, axle 4 meshes to the tangential force of axle 5 to the bottom right by gear 8-4 and gear 8-5, axle 5 is given axle C tangential force left by gear 8-5 and gear C 1 engagement, axle C meshes the tangential force that makes progress to axle A by gear C and gear A, and this power just in time tangential force direction with the rotation of axle A is identical.Also be identical in like manner with the tangential force direction of the rotation of axle A from the power of axle A → axle C → axle 5 → axle 4 → axle 3 → axle B → axle A.
Working procedure:
As shown in Figure 2, motor drives axle A rotates, gear 8-A and gear 8-A1 drive axle B by gear B and gear 8-C respectively and axle C rotates, axle B drives axle 3 by gear 8-B1 and gear 8-3 engagement and rotates, gear 8-3 also meshed with gear 8-4 when axle 3 drove axle 2 and rotates by gear 8-3 and gear 8-2 engagement, and axle 2 is by a gear 8-2 and gear 8-1 engagement drive 1 rotation; Axle C drives axle 4 rotations by the engagement of gear 8-C1 and gear 8-4, axle 4 drives axle 5 by gear 8-4 and gear 8-5 engagement and rotates, axle 5 drives axle 6 by gear 8-5 and gear 8-6 engagement and rotates, and axle 6 drives axle 7 by gear 8-6 and gear 8-7 engagement and rotates.Axle A, axle B, axle 3, axle 4, axle 5, axle C cog by axle and form a closed loop transmission like this.
