Background technique
Large inclination working surface tractive unit is that coal mining machine, development machine etc. need to be ideal when more than using on the face of 45 degree of inclination angles
Traction mechanism.With China's demand that Coal Mechanical profession is mined at this stage, early 1980s are large quantities of to draw coal feeder
Equipment, by digestion, absorption, raising, especially in recent years with the development of fully mechanized mining technology, it is millions of that annual output has occurred in the country
Tonne even the super working face of ten-million-ton scale.To make fully mechanized mining technology become the key technique that coal mine efficiently produces.In recent years
Come, swift and violent using mechanical equipment development on large inclination working surface, special tractive unit is gradually widely used.
Tractive unit refers to autonomous closure formula transmission device between prime mover and working machine, for reducing revolving speed and correspondingly increasing
Big torque.Tractive unit is mainly made of gear, axis, bearing, cabinet and its attachment, since gear drive can be in the smallest shape
Under conditions of size, weight and friction loss, it is possible to obtain higher reliable transmission, therefore mainly used in tractive unit
Gear drive.And be growing using the use scope of planetary reduction gear, it is widely used in coal mining equipment, is
Indispensable mechanical driving device.And more unique fixation is installed in existing traction device, between reduction gearing and shaft,
Especially afterbody reduction gearing, handling are more inconvenient.
Utility model content
Facilitate installation the technical problem to be solved by the present invention is to provide a kind of reduction gearing, and applicability is high inclines greatly
Angle working face traction device.
In order to solve the above-mentioned technical problem, a kind of the technical solution adopted in the utility model are as follows: large inclination working surface traction
Device, including shell, further include traction main shaft, and primary speed-down gear set, double-reduction gear group and traction planet head are being led
Draw and is additionally provided with brake axle group between main shaft and primary speed-down gear；It draws shape star head and connects splined shaft, splined shaft is for driving
The rotation of rack rails wheel；The double-reduction gear group includes rotation axis, and reduction gearing and driving gear are provided in rotation axis, described
Reduction gearing and the engagement of primary speed-down gear set, driving gear engage drive traction planet head rotation, rotation with traction planet head
Bearing is provided at the top of axis and between reduction gearing and driving gear；It is convex that the reduction gearing outside is evenly distributed with arc
Tooth, centre are provided with fixation hole circle, and reduction gearing surface is additionally provided with a boss, threaded securing bores are provided on boss；
It is also provided with flange on the rotating shaft, threaded securing bores corresponding with boss are provided on flange, with the spiral shell across boss and flange
Reduction gearing and rotation axis are carried out axial restraint by nail.
Further, the lightening hole that through-thickness runs through reduction gearing is additionally provided in the reduction gearing.
Further, the rotation axis end is provided with an end cap connected to the housing, and end cap is to turning end
Bearing carries out axial restraint, and outer end face and the shell of the bearing offset, and the annular that annular cross section is rectangle is provided on end cap
Groove, is provided with O-ring seals in annular groove, and O-ring seals and shell are squeezed and deformed to form oil enveloping structure.
From above-mentioned technical proposal it can be seen that the utility model has the advantage that double-reduction gear group is easy for installation,
The axial restraint of reduction gearing may be implemented using the structure that flange and protrusion match, and the length of rigging screw can also be controlled
Degree adjusts the axial position of reduction gearing to provide suitability.
