Description
Technical field
The present invention relates to a kind of running gears for coalcutter, belong to coalcutter technical field.
Background technique
With the development of China's coal-mine fully-mechanized mining equipment, equipment is also more and more abundant, and coalcutter is most important mining opens
Adopt one of equipment.The running gear of coalcutter is the device of direct mobile coalcutter, passes through its traveling wheel and scratch board conveyor
Track engaged transmission of walking is realized.Due to being engaged between traveling wheel and the walking track of transporter by helical gear or spur gear,
It is generally lower than transporter rack rails wheel intensity to lead to its intensity, and shakes will lead to traveling wheel and walking track in the process of walking
Left or right side contact, and then it is vulnerable after causing traveling wheel to be worn, eventually lead to the running gear intensity of coalcutter all
It is not high.And the piston shoes of running part carry the weight of entire coalcutter, and have guiding role；In coalcutter moving process
It can easily be contacted with pin rail and so as to cause the left or right side of piston shoes in movement there is a situation where being tilted to the left or being tilted to the right
Sliding friction occurs in the process, to also be easy to cause it that wear-out failure occurs.So traveling wheel break of gear tooth and guide slip shoe
Rupture is the most common two kinds of failure modes of running part.Since running gear can not only realize coalcutter in the operating condition
The adjusting of walking and the speed of travel, weight of the piston shoes also subject to entire coalcutter.Therefore the intensity direct relation of running part
The intensity of entire coalcutter work and adapt to the ability of environment, also have important influence to production efficiency.The two positions
Coalcutter will be will cause after failure to work, to cause huge economic loss even casualty accident.
The problem of for failure easy to wear existing for traveling wheel and guide slip shoe, currently used mode are to improve traveling wheel
And the material of piston shoes, increase the service life of traveling wheel and guide slip shoe in turn by using wear-resistant material or high-strength material,
But it is this by way of alternate material, not only increase more process and processing cost, but also after its actual use
The effect improved service life, it is still unobvious, to be unable to satisfy the demand of coal mining.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of running gears for coalcutter, can guarantee
Transmission stability between traveling wheel and walking track, so that the friction for reducing traveling wheel between track of walking, improves walking
In addition the service life of wheel substitutes sliding friction using rolling friction, can reduce the friction of guide slip shoe and track two sides of walking
Power, so that the service life of guide slip shoe is effectively improved, it is final to guarantee coalcutter operation stability.
To achieve the goals above, the technical solution adopted by the present invention is that: a kind of running gear for coalcutter, including
Travelling box body, drive shaft, idler shaft I, idler shaft II, sprocket shaft and guide slip shoe, drive shaft, idler shaft I, idler shaft II
It is installed in travelling box body with sprocket shaft, drive shaft, idler shaft I, idler shaft II and sprocket shaft pass sequentially through gear engagement
Transmission, sprocket shaft are equipped with traveling wheel, and traveling wheel is in the walking track of drag conveyor, and guide slip shoe is by two guiding groups
Part composition, two guidance sets are respectively at the two sides of walking track, and the upper end is embedded in the medial surface of travelling box body lower end,
It is equipped with double helical tooth in the outer circumference surface and walking track of the traveling wheel, two guidance sets are equal close to the side of walking track
It opens up fluted, multiple balls is equipped in groove, further includes end casing, strip through-hole is opened up on end casing, end casing is fixed on
Ball rolls groove surfaces in groove and ball part is from strip through-hole protrusion for making, and the width of the strip through-hole is smaller
In the diameter of ball.
Further, the depth of the groove is the radius of ball, and the width of groove is slightly larger than the diameter of ball, the length of groove
Degree is slightly larger than the sum of the diameter of multiple balls.
Further, the shape of the groove is strip, and end casing is rectangle.
Further, the herringbone tooth width on the traveling wheel is slightly less than the herringbone tooth width of walking track.
Further, the end casing is bolted on groove surfaces.
Further, the side of the strip through-hole and the side of groove are concordant, and the section of the strip through-hole other side is circular arc
Shape, and it is arc-shaped slightly larger than ball.
Further, the material of the ball is antifriction metal (AFM).
Further, the herringbone pitch of teeth of the walking track is 147.
Compared with prior art, the present invention using travelling box body, drive shaft, idler shaft I, idler shaft II, sprocket shaft and
Guide slip shoe combines mode, and double helical tooth is respectively set in traveling wheel and walking track and is driven, since double helical tooth is opposite
In straight-tooth or helical teeth, with transmission stability, noise is small, greatly reduces axial force, so that traveling wheel be made to move in walking track
Axial float will not occur when dynamic, greatly reduce the contact friction of traveling wheel with track two sides inner wall of walking, improve traveling wheel
Service life；In addition groove is opened up on guide slip shoe, and ball is set in groove, when coalcutter movement shakes,
The ball of the left or right side of guide slip shoe can be with two side contacts of walking track, to make guide slip shoe by ball and walk
Track is rolling friction, greatly reduces frictional force compared with existing sliding friction, to effectively improve making for guide slip shoe
It finally ensure that coalcutter operation stability due to improving the service life of traveling wheel and guide slip shoe with the service life.
