Abstract
The utility model discloses a duplex gear wheel speed reducing device which can change the positions of an input shaft and an output shaft as required. The duplex gear wheel in the speed reducing device is assembled by a large and a small gear wheels with opposite tooth surface, inclination and direction and is installed on an input stepped shaft and an output stepped shaft through a bearing, but the input stepped shaft and the output stepped shaft are installed on a box body separately through position changing bearing blocks.
Description
The utility model relates to a kind of reducer arrangement, especially can change input shaft and the position of output shaft and retarder easy to assembly in a casing according to different needs.
At present, known retarder has JZQ type, ZD type, ZL type, ZS type and two-gang gear reducer (to see Chinese patent: 87205238.9) etc., its input shaft and output shaft are installed in the casing by bearing fixing respectively, can not change the position of input shaft and output shaft as required.For known two-gang gear reducer (see Chinese patent: 87205238.9), first input shaft and output shaft are optical axises since the axle longer, the axle with duplicate gear on the bearing fit tolerance very little, the installation duplicate gear very difficult; Its two duplicate gear is major part in retarder, and quantity is many, is that integral material is made owing to join gear again, can not make up, and the large and small gear distance on the duplicate gear is little, and manufacture difficulty is big; In addition, for the duplicate gear of pitch face, the flank of tooth gradient direction of its large and small gear is identical, and unidirectional axial force is very big, has increased bearing, the axial force of casing and input shaft, output shaft.
The purpose of this utility model provides a kind of two-gang gear reducer, it not only can be according to different needs, in same casing, change the position of input shaft and output shaft, and duplicate gear can make up on request, it is easy to manufacture, easy to assembly, alleviated unidirectional axial force of bearing, casing, input shaft and output shaft simultaneously.
The purpose of this utility model is achieved in that two-gang gear reducer, form by casing, input shaft, output shaft, input gear, output gear and duplicate gear, on the position of casing installation input multidiameter shaft and output multidiameter shaft, the displacement bearing support is housed, duplicate gear is by large and small Gear combination, and by Bearing Installation on input multidiameter shaft and output multidiameter shaft.According to different needs, input shaft and output shaft can change its position by the displacement bearing support.The manufacturing of pitch face duplicate gear is after large and small gear is processed respectively, and the large and small gear opposite with flank of tooth gradient direction combines, and the manufacturing of duplicate gear just is easy to like this.Because the flank of tooth gradient direction of the large and small gear on the duplicate gear is opposite, has just offset unidirectional axial force in the practical application.In two-gang gear reducer, the transmission of torque force is undertaken by input shaft input end, input gear, duplicate gear, output gear, output shaft output terminal, on input shaft and output shaft, install this fragment position of duplicate gear, be transmitting torque power not, after making stairstepping, shortened the mounting point of duplicate gear bearing, very convenient to the assembling duplicate gear, do not influence the mechanical strength of input shaft and output shaft again.
Owing to adopt such scheme, make novel two-gang gear reducer, not only can change the position of input shaft and output shaft on demand, and the manufacturing of duplicate gear is easy to, easy to assembly, stress equalization during its retarder work.
Example structure figure below in conjunction with two-gang gear reducer further specifies the utility model.
Among the figure 1, casing, 2, bearing bracket stand, 3, end cap, 4, the input multidiameter shaft, 5, input gear, 6, the gearwheel of duplicate gear, 7, the small gear of duplicate gear, 8, bearing, 9, input shaft displacement bearing support, 10, output shaft displacement bearing support, 11, the output multidiameter shaft, 12, output gear.
In the drawings, the input multidiameter shaft ［ 4 ］ of two-gang gear reducer and output ladder ［ 11 ］ are installed on the casing ［ 1 ］ by input shaft displacement bearing support ［ 9 ］ and output shaft displacement bearing support ［ 10 ］ respectively, according to different needs, change the position of input shaft displacement bearing support ［ 9 ］ and output shaft displacement bearing support ［ 10 ］, just can change the position of input multidiameter shaft ［ 4 ］ and output multidiameter shaft ［ 11 ］.Input shaft displacement bearing support ［ 9 ］ and output shaft displacement bearing support ［ 10 ］ are made up of end cap ［ 3 ］, bearing ［ 8 ］ and bearing bracket stand ［ 2 ］, and its external diameter is identical.Duplicate gear carries out combinating face by the gearwheel ［ 6 ］ of duplicate gear and the small gear ［ 7 ］ of duplicate gear on the contrary by large and small two gear teeth face gradient directions, and is installed on input multidiameter shaft ［ 4 ］ and the output multidiameter shaft ［ 11 ］ by bearing ［ 8 ］.The transmission of two-gang gear reducer torque force is input end, input gear ［ 5 ］, the duplicate gear by input multidiameter shaft ［ 4 ］ among the figure, output gear ［ 12 ］, and the output terminal of output multidiameter shaft ［ 11 ］ carries out.Duplicate gear has the effect of offsetting unidirectional axial force, stress equalization when making two-gang gear reducer work.
