Abstract
A kind of coal-winning machine nonholonomic constraints idle pulley, self-aligning bearing (3) is arranged on idle pulley (5) endoporus, self-aligning bearing (3) passes through rib and check ring (4) axial restraint of idle pulley (5), self-aligning bearing (3) endoporus installs lining (2), and self-aligning bearing 3 is fitted on bearing pin (1).This utility model only installs a self-aligning bearing on idler interior bore, and by rib and the check ring axial restraint of idle pulley, self-aligning bearing endoporus installs lining, reassembles on set bearing pin.Owing to self-aligning bearing has regulation of mental activities effect, can swing, a self-aligning bearing is only installed in idle pulley, makes idle pulley can swing with self-aligning bearing, balance two side gears not parallel owing to processing the axis produced.Transmission when this utility model is applied to Dual-motors Driving, between two motors.Owing to self-aligning bearing 3 has regulation of mental activities effect, can swing, a self-aligning bearing 3 is only installed in idle pulley 5, makes idle pulley 5 can swing with self-aligning bearing 3, balance two side gears not parallel owing to processing the axis produced.
Description
Technical field
This utility model relates to a kind of coal-winning machine nonholonomic constraints idle pulley.
Background technology
In girdle uses, it is desirable to coal-winning machine fuselage is short but enough power, to adapt to the undulation in coal seam,
There is enough crossing coal and cross machine spatial altitude simultaneously.Present most of low seam mining machinery all uses Dual-motors Driving, to do
Big to the thin power of fuselage.But Dual-motors Driving is owing to there being two driving wheels, needs idle pulley to connect between two driving wheels.At present
Tradition idle pulley is all the structure using Complete Bind, in the case of Dual Drive, causes owing to the axis of processing generation is not parallel
Idle pulley and bearing life between two driving wheels are the lowest.When designing the structure of Dual-motors Driving it is necessary to sufficiently strengthen double driving
Idle pulley between driving wheel and bearing, both added cost, adds again physical dimension, and safety coefficient is the highest.
Summary of the invention
The purpose of this utility model is: by a kind of coal-winning machine nonholonomic constraints idle pulley, solves under Dual-motors Driving, due to
Process the not parallel idle pulley caused between two driving wheels of axis of generation and the problem that bearing life is the lowest. skill of the present utility model
Art scheme is: a kind of coal-winning machine nonholonomic constraints idle pulley, self-aligning bearing (3) is arranged on idle pulley (5) endoporus, self-aligning bearing (3)
By rib and check ring (4) axial restraint of idle pulley (5), self-aligning bearing (3) endoporus installs lining (2), and self-aligning bearing 3 is joined
It is contained on bearing pin (1).This utility model only installs a self-aligning bearing on idler interior bore, by rib and the spring catch of idle pulley
Circle axial restraint, self-aligning bearing endoporus is installed lining, is reassembled on set bearing pin.Owing to self-aligning bearing has regulation of mental activities effect, permissible
Swing, a self-aligning bearing is only installed in idle pulley, makes idle pulley can swing with self-aligning bearing, balance two side gears due to processing
The axis produced is not parallel.
Transmission when this utility model is applied to Dual-motors Driving, between two motors.Owing to self-aligning bearing (3) has regulation of mental activities
Effect, can swing, and only installs a self-aligning bearing (3), make idle pulley (5) can swing with self-aligning bearing (3) in idle pulley (5),
Balance two side gears not parallel owing to processing the axis produced.
The beneficial effects of the utility model are:
1. improve the service life of idle pulley and bearing.
2. save cost, and reduced the spacing between driving wheel, reduce volume.
Accompanying drawing explanation
Fig. 1 is this utility model one nonholonomic constraints idle pulley schematic diagram
Fig. 2 is general Complete Bind idle pulley schematic diagram
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described further:
A kind of coal-winning machine nonholonomic constraints idle pulley as shown in Figure 1, self-aligning bearing 3 is arranged on idle pulley 5 endoporus, regulation of mental activities axle
Holding 3 rib by idle pulley 5 and check ring 4 axial restraints, self-aligning bearing 3 endoporus installs lining 2, and self-aligning bearing 3 is fitted in
On bearing pin 1.During as in figure 2 it is shown, this nonholonomic constraints idle pulley is applied to Dual-motors Driving, the transmission between two motors.Owing to adjusting
Mandrel is held 3 and is had regulation of mental activities effect, can swing, and only installs a self-aligning bearing 3 in idle pulley 5, makes the idle pulley 5 can be with self-aligning bearing
3 swing, and balance two side gears not parallel owing to processing the axis produced.
