Abstract
Coaxial two-gang gear reducer, it is a kind of novel mechanical transmission device, overcome that the existing transmission speed ratio of concentric cylinder gear reducer was little in the past, bulky shortcoming, make it to become a kind of simple in structure, compactness, easy processing, hundreds of thousands) and reversible retarder arranged volume is very little, and transmission speed ratio is very big (can to reach 1:.Its major character is: 1, coaxial two-gang gear reducer has input shaft, jack shaft and output shaft in it.2, jack shaft fix or by Bearing Installation on the casing of retarder.3, on the axle one or more duplicate gears are housed.4, duplicate gear all by Bearing Installation on axle.
Description
The present invention is a kind of coaxial two-gang gear reducer, it belongs to a kind of mechanical transmission, coaxial two-gang gear reducer is made up of casing, input shaft, input gear, jack shaft, output shaft, output gear and duplicate gear, on the axle duplicate gear is housed, input gear and output gear are fixedly mounted on respectively on input shaft and the output shaft, input shaft and output shaft by Bearing Installation on casing.
The employed coaxial speed reducer of people has the concentric cylinder gear reducer, plane table thermoconductivity meter, cycloidal-pin wheel retarder and harmonic speed reducer at present.The concentric cylinder gear reducer, have simple in structure, the advantage of easy processing, but the transmission speed ratio of concentric cylinder gear reducer is less.In the concentric cylinder gear reducer, its structure is that one or two gear is arranged on the axle, and gear generally is fixedly mounted on the axle with key, the gear engagement on gear on the axle and the adjacent disalignment.This coaxial speed reducer is owing to the narrow limitation of mode of structure, and its quantity must Duo 1 than the quantity of gear mesh.(1 pair of gear of 2 axles, 2 pairs of gears of 3 axles).As making the retarder of big transmission speed ratio, will increase the necessary simultaneously number that increases axle of number of gears purpose, perhaps use the gear mesh of big transmission speed ratio.The volume of concentric cylinder gear reducer just must be done very hugely like this, and its weight also increases greatly.So in order to obtain big transmission speed ratio, people just must use plane table thermoconductivity meter, cycloidal-pin wheel retarder and harmonic speed reducer, and these reducer structure complexity, requirement on machining accuracy is very high, and the manufacturing process difficulty is bigger, what have also needs special device, so general producer is difficult to make.
Purpose of the present invention is that manufacturing is a kind of simple in structure, and transmission speed ratio is very big, the coaxial two-gang gear reducer that volume is less.
This novel coaxial two-gang gear reducer, input shaft, jack shaft and output shaft are housed in it, the input gear fixedly is housed on the input shaft, output gear also fixedly is housed on the output shaft, remove in addition, one or more duplicate gears also can be installed in series on input shaft or the output shaft.Jack shaft fix or by Bearing Installation on the casing of retarder, its axle on one or more duplicate gears are housed.Duplicate gear on input shaft, output shaft and the jack shaft all by Bearing Installation on axle, and locate with the sleeve that is enclosed within on the axle.The input shaft of coaxial two-gang gear reducer, jack shaft, output shaft are the cylinder profile shafts, and the distance between the large and small gear of duplicate gear is little, and pitch wheel is right on axle, and its centre distance all equates.When power rotated coaxial two-gang gear reducer, the duplicate gear in the retarder did not rotate synchronously with axle.
Coaxial two-gang gear reducer is reversible, and when use was exchanged in input and output, retarder had just become speed increaser.
Fig. 1 is the transmission sketch of 4 grades of coaxial two-gang gear reducers.This retarder is made of casing [1], input shaft [2], input gear [3], jack shaft [9], output shaft [3], output gear [7] and duplicate gear [4], [5], [6].Input gear [3] and output gear [7] are fixedly mounted on respectively on input shaft [2] and the output shaft [8], jack shaft [9] is fixedly mounted on the casing [1] of retarder, duplicate gear [4], [6] by Bearing Installation on jack shaft [9], duplicate gear [5] by Bearing Installation on output shaft [8], the two ends of input shaft [2] and output shaft [8] are installed on the casing [1] of retarder by bearing [11], the input gear [3] of retarder and the engagement of the gearwheel of duplicate gear [4], the gearwheel engagement of the small gear of duplicate gear [4] and duplicate gear [5], and the engagement of the gearwheel of the small gear of duplicate gear [5] and duplicate gear [6], the small gear of last duplicate gear [6] meshes with output gear [7].When power rotates input shaft [2], to import gear [3] and drive duplicate gear [4] rotation, duplicate gear [4] drives duplicate gear [5] and rotates, and duplicate gear [5] drives duplicate gear [6] rotation, last duplicate gear [6] drive output gear [7] rotates.In transmission process, the biography speed of the transmission velocity ratio input shaft [2] of duplicate gear [4] is low, the biography speed of the transmission velocity ratio duplicate gear [4] of duplicate gear [5] is low, and the biography speed of the transmission velocity ratio duplicate gear [5] of duplicate gear [6] is low, and the biography speed of the transmission velocity ratio duplicate gear [6] of output gear [7] is low.Whole transmission process has passed through 4 decelerations.
Fig. 2 is the transmission sketch of coaxial 6 grades of two-gang gear reducers.Input gear [3] and output gear [7] fixedly are housed respectively on this input shaft of speed reducer [2] and the output shaft [8], in addition the duplicate gear [13] that also has been installed in series on input shaft [2], a duplicate gear [15] also has been installed in series on output shaft [8].Jack shaft [9] is fixedly mounted on the casing [1], and 3 duplicate gears [12], [14] and [16] have been installed in series on its axle.Whole transmission process has passed through 6 decelerations.
Fig. 3 is the transmission sketch of 8 grades of coaxial two-gang gear reducers.Input shaft of speed reducer [2] goes up input gear [3] fixedly is housed, and output shaft [8] is last fixedly to be equipped with output gear [7] and 3 duplicate gears [18] that have been installed in series, [20] and [22].Jack shaft [9] is fixedly mounted on the reduction case [1], and 4 duplicate gears [17], [19], [21] and [23] have been installed in series on its axle.Whole transmission process has passed through 8 decelerations.
Fig. 4 is the transmission sketch of 5 grades of coaxial two-gang gear reducers.2 jack shafts [9] that are fixed on the casing [1] are arranged among the figure.
Fig. 5 is the structural drawing of 8 grades of coaxial two-gang gear reducers.
Coaxial two-gang gear reducer, a plurality of duplicate gears can be installed in series on its axle.It is compared with existing concentric cylinder gear reducer, have that compact structure, transmission speed ratio are very big, volume is little, lightweight advantage, it is compared with harmonic speed reducer with plane table thermoconductivity meter, cycloidal-pin wheel retarder, has simple in structure, easy processing, advantage that transmission speed ratio is bigger.Coaxial two-gang gear reducer is a kind of compact structure, simple, easy processing, transmission speed ratio is very big, volume is less and have reversible retarder.Coaxial two-gang gear reducer can be used as the transmission device of various complete machines, is widely used in all trades and professions such as machinery, metallurgy, mine, building, cement, weaving, light industry.
