Description
Technical field
It the utility model is related to a kind of mine shearer traveling box walking wheel assembly.
Background technology
Mine shearer traveling box walking wheel assembly belongs to open type gear driving system, without any lubrication, mines
When machine is walked, have and be subject to substantial amounts of cut, dead weight shock loading, cause walking wheel of coal cutter to damage, often cause traveling wheel
Play gear；Since traveling wheel often damages, to replace frequently, traveling wheel system is in the end of transmission, replaces complex procedures,
Need to tear open pin rail, unit track lowering during replacement, and with specific purpose tool depoling axis, the walking wheel assembly of damage could be taken out；Due to well
Under have coal dust, be unfavorable for opening and inspecting assembling and replace, can only integral replacing walking wheel assembly；New walking wheel assembly transport in place into
Row installation, the time generally to stop production are longer.Simultaneously as walking wheel assembly processing technology is complicated, and requirement on machining accuracy
Height, the cost for replacing walking wheel assembly are higher.
The content of the invention
The utility model aim is to overcome the shortcomings of above-mentioned prior art, there is provided a kind of assembly process is simple, be conveniently replaceable,
Cost can effectively be reduced, shorten the interchangeable walking wheel assembly used on the mine shearer traveling box of replacing construction.
It is close that the utility model includes driven wheel, driven wheel end cap, traveling wheel, traveling wheel end cap, roller bearing and cascade ring
Seal.Driven wheel is the boss-shaped with external splines, and boss is embedded with roller bearing, and traveling wheel is the groove with internal spline
Shape, groove size match with driven wheel boss size external splines, and traveling wheel is assemblied in outside driven wheel boss by groove internal spline
By spline assembly connection it is an entirety between driven wheel and traveling wheel on spline；Driven wheel end cap, traveling wheel end cap difference
The outside of driven wheel and traveling wheel is installed on by fixing bolt, roller bearing is sleeved on mandrel, can be rotated simultaneously relative to mandrel
Slide, mandrel is supported on walking tank shell by pin sleeve, roller bearing inner sheath and driven wheel end cap, traveling wheel end cap it
Between cascade ring sealing ring is housed, sealing bearing prevents that calcium-base grease outflow is exterior and stops that coal dust enters Bearing inner.Roller
The model ZM290A of bearing.
The traveling wheel flank of tooth carburizing depth 2.5-3mm, quenching hardness HRC58-62, core hardness HRC36.Profile error≤
0.15mm, pitch error≤0.17mm, gear ring run-out error≤0.24mm. ask high, and it is special that material requires, wheel gear of walking
Intensity requirement is higher than ordinary gear, and the requirement such as roll flute intensity, precision process is high.This is also walking wheel of coal cutter master of high cost
Want reason.
Driven wheel is in guide slip shoe, and driven wheel is meshed with pinion gear on traveling box, and traveling wheel is mounted in guide slip shoe
Outside, guide slip shoe are sleeved in pin rail, support a part of weight of coalcutter, and are play the guiding role, while bear traveling wheel
Lateral force when radial load and coalcutter work.Traveling wheel is meshed with the pin rail of Scraper Conveyor in Mining Face, drives coalcutter
Walking, guide slip shoe is oriented to coalcutter by pin rail, and ensures that traveling wheel is normally engaged with pin rail.
When traveling wheel damages, underground site can very easily pull down end cap at traveling wheel, and bad traveling wheel is removed, and replace
One good traveling wheel is installed, process is simple, it is not necessary to which well assembles in transport, shortens break down time, often changes once, cost
About 20,000 yuan can be reduced.And spare a whole set of walking wheel assembly is not required in underground, only spare replaceable traveling wheel, just
Installed in workers carry, reduce cost and loss.Traveling wheel assembly process is simple, is conveniently replaceable, and effectively reduces cost, shortens
Break down time.

Embodiment
Driven wheel 1 is the boss-shaped with external splines, and boss is embedded with roller bearing 6, and traveling wheel 4 is with internal spline
Groove-like, groove size match with 1 boss size external splines of driven wheel, and traveling wheel 4 is assemblied in driven wheel 1 by groove internal spline
By connecting 9 assembly connection of spline it is an entirety between driven wheel 1 and traveling wheel 4 on boss external splines；Driven wheel end cap 2,
Traveling wheel end cap 5 is installed on the outside of driven wheel 1 and traveling wheel 4 by fixing bolt 3,10 respectively, and roller bearing 6 is sleeved on core
On axis 8, it can rotate and slide relative to mandrel 8, mandrel 8 is supported on walking tank shell by pin sleeve, in 6 inner sleeve of roller bearing
There is cascade ring sealing ring 7 between driven wheel end cap 2, traveling wheel end cap 5, sealing bearing prevents that calcium-base grease outflow is exterior simultaneously
Stop that coal dust enters Bearing inner.The model ZM290A of roller bearing 6.Fixing bolt 3,10 is using the spiral shell of interior hexagonal M × 12
Bolt.
The power of planetary reduction gear is passed to the pinion gear 12 of traveling box, pinion gear 12 and 1 phase of driven wheel by splined shaft 11
