The utility model adopts the speed reduction box to transmit the force generated by the drilling rod of a working mining rig to the frame of the mining rig, to improve the force condition on the speed reduction box, reduce the size of the speed reduction box, reduce the volume of the mining rig, reduce production box and improve utilization ratio.
Description
Technical field
The utility model belongs to the coal-cutting machinery field, is specifically related to a kind of structure of girdle Coal-mining drilling machine special retarding case.
Background technique
The coal in China reserves are abundant, but the great majority working seam belongs to girdle and the ultra-thin coal seam of 0.4M-1.0M, and the spiral Coal-mining drilling machine is that a kind of can the solution approaches the coal excavation apparatus of exploiting, improve coal recovery rate with ultra-thin coal seam.Speed reducer is the transmission part of Coal-mining drilling machine, is used for changing the low rotation speed large torque from the little moment of torsion of high rotating speed of motor to drilling rod, satisfies the actual demand of mining.The speed reducer boundary dimension of existing coal winning machine is big, and the manufacture cost height takes up room, the easy stress deformation of casing during work.
Summary of the invention
The purpose of this utility model is: a kind of girdle Coal-mining drilling machine special retarding case is provided, the power that drilling rod produced when coal winning machine was worked is delivered on the support of coal winning machine by speed reducer, improve speed reducer casing force-bearing situation, and reduce taking up room of speed reducer boundary dimension and coal winning machine, reduce manufacture cost, increase operation rate.
Technical solution of the present utility model is: this speed reducer comprises housing, one-level bevel gear shaft, secondary tooth axle, three grades of tooth axles and output shaft, one-level bevel gear shaft, secondary tooth axle, three grades of tooth axles and output shaft through Bearing Installation in housing, one-level bevel gear on the one-level bevel gear shaft engagement secondary tooth axle, tertiary gear on the secondary gear on three grades of tooth axles of secondary tooth axle engagement, three grades of tooth axle engagement output shafts.
In the girdle Coal-mining drilling machine special retarding case of the present utility model, output shaft is installed in the housing by thrust-bearing and bearing support.
In the girdle Coal-mining drilling machine special retarding case of the present utility model, secondary tooth axle, three grades of tooth axles and output shaft are angular distribution.
During installation, the housing of this speed reducer is fixed on the support of coal winning machine, connects the drilling rod of coal winning machine on the output shaft, and every coal winning machine is installed two speed reduceres, and speed reducer disposes along coal winning machine drilling rod symmetry center face bilateral symmetry; During use, one-level bevel gear shaft, secondary tooth axle, three grades of tooth axles will be changed into low rotation speed large torque is exported to coal winning machine by output shaft drilling rod through commutation and deceleration from the little moment of torsion of high rotating speed of motor.
The utlity model has following advantage: 1. adopt three grades of decelerations, the first order is a bevel gear drive, second, third level is a column gear transmission, first order bevel gear drive is used to change the gyration center direction from motor to the coal winning machine drilling rod, required rotating speed when first, second and third grade column gear transmission then is used for output speed with motor and is reduced to the work of coal winning machine drilling rod; The power that produces when 2. the coal winning machine drilling rod is worked is delivered on the coal winning machine support that speed reducer is installed through thrust-bearing and bearing support by the output shaft of speed reducer, reduced the stress deformation of speed reducer casing, improved speed reduction gear box transmission engagement effect, the working stability and the Security that improve speed reducer; 3. the secondary tooth axle of this speed reducer, three grades of tooth axles and output shaft are angular distribution, have shortened the crow flight distance between secondary tooth axle and the output shaft, and speed reducer casing length is reduced, thereby reduce the coal winning machine floor space; 4. this speed reducer carrying is big, stable working, and the transmission efficiency height can be widely used on the girdle spiral Coal-mining drilling machine.
