In such scheme, described attachment hole axis is preferably vertical with splicing surface.
In such scheme, described link is screw and abutment sleeve, on the adjacent two gear ring sections of circumferencial direction splicing in corresponding two attachment holes, one is through hole with the level, one is threaded step blind hole, step through-hole is identical with step blind hole internal diameter, setting sleeve places in the through hole of above-mentioned step and the step blind hole simultaneously and is mated, screw passes the setting sleeve front portion and cooperates with the blind threaded part of step, screw head is by the step end face location of step through-hole, the design of described through hole with the level helps the installation of ring gear on the one hand, and the aspect helps the location of gear ring joint when the processing ring gear in addition.
In such scheme, in casing, can be provided with two-stage planet pair at least, the sun gear of described previous stage planetary pinion pair is connected with input shaft, planet wheel is connected with sun gear in the primary planet pinion pair of back by coupled planet carrier, and the planet wheel of back one-level passes through coupled planet carrier and links to each other with output shaft.
In such scheme, the planet wheel of described previous stage planetary pinion pair vertically can by two sections assembled because the installing space of previous stage is less, so the installation of previous stage planet wheel is convenient in such design.
In such scheme, described planet wheel is at least more than two, also can have only a planet wheel.
The present invention is particularly suitable for the mine lift winch and uses, but is not limited only to miningly, but also is applicable to all size type engineering machinery.
Advantage of the present invention is as follows:
1, adopt herringbone tooth transmission contact ratio height, the ability of transmission stability and output torque is higher;
2, adopt herringbone tooth to eliminate the axial force that the helical teeth transmission produces, the axially locating of speed reducer is easy;
3, the more piece two-part structure of ring gear employing has solved sun gear, planet wheel and ring gear difficult problem has been installed;
4, volume is little, and noise is low.
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
