Abstract
A kind of coal-winning machine composite curve road wheel, the gear teeth curve of road wheel is made up of (2) two sections of curves of involute (1) and circular arc, is circular arc (2) close to tooth top position, is involute (1) close to root portions.Existing involute or cycloid are replaced by composite curve, the tooth form of road wheel is completed, processes composite curve road wheel.Composite curve road wheel (3) is added much in root position than cycloid road wheel (4) thickness, strengthens road wheel tooth root, solves the phenomenon of easy broken teeth in road wheel use.Composite curve road wheel (3) uses arc transition in tooth top position, smaller than involute sprocket (5) transverse tooth thickness, and rounding off, solves Undercutting Phenomenon in involute sprocket gear pair engagement process.
Description
Technical field
The utility model is related to a kind of coal-winning machine composite curve road wheel.
Background technology
Walking wheel of coal cutter is the final executive module of shearer haulage mechanism, and coal-winning machine passes through road wheel and transporter
Pin row is engaged, and is walked back and forth on working face.Because road wheel is final executive module, working environment is very severe, walking
Wheel is engaged in unlubricated operating mode with pin row for a long time, serious wear.In coal-winning machine, road wheel is wherein weak link.
At present, domestic road wheel gear teeth curve has two kinds, involute and cycloid.Involute curve road wheel is engaged with driving wheel
When, because the number of teeth is few, root can be produced and cut, the dedendum strength of driving wheel and road wheel is died down, the life-span of driving wheel is had a strong impact on.
Cycloid road wheel is due to curve characteristic itself, and the tooth root of road wheel is thin, and the road wheel life-span is low.
Existing walking form of gear tooth general single use cycloid or involute, involute curve road wheel with driving
During wheel engagement, because the number of teeth is few, root can be produced and cut, the dedendum strength of driving wheel and road wheel is died down, have a strong impact on driving wheel
Life-span.Cycloid road wheel is due to curve characteristic itself, and the tooth root of road wheel is thin, and the road wheel life-span is low.
The content of the invention
The purpose of this utility model is：There is provided and a kind of solve current involute and cycloid road wheel life-span in actual applications
Low coal-winning machine composite curve road wheel.The technical solution of the utility model is：A kind of coal-winning machine composite curve road wheel, walking
The gear teeth appearance curve of wheel is compound curve shape, and the composite curve connects structure by (2) two sections of curves of involute (1) and circular arc
Into close tooth top position is circular arc (2), is involute (1) close to root portions.
The beneficial effects of the utility model are：
1. as shown in Fig. 2 composite curve road wheel (3) is added much in root position than cycloid road wheel (4) thickness,
Strengthen road wheel tooth root, solve the phenomenon of easy broken teeth in road wheel use.
2. as shown in figure 3, composite curve road wheel (3) uses arc transition in tooth top position, than involute sprocket (5)
Transverse tooth thickness is smaller, and rounding off, solves Undercutting Phenomenon in involute sprocket gear pair engagement process.
Brief description of the drawings：
Fig. 1 is the utility model composite curve road wheel schematic diagram
Fig. 2 is the utility model composite curve road wheel and cycloid walking gear teeth contrast schematic diagram
Fig. 3 is the utility model composite curve road wheel and involute sprocket tooth contrast schematic diagram
Embodiment
A kind of coal-winning machine composite curve road wheel as shown in Figure 1, the gear teeth appearance curve of road wheel is compound-curve
Shape, the composite curve is connected and composed by 2 two sections of curves of involute 1 and circular arc, is circular arc 2 close to tooth top position, close to root portion
It is divided into involute 1.
As shown in Fig. 2 composite curve road wheel 3 is added much in root position than the thickness of cycloid road wheel 4, strengthen row
Walk to take turns tooth root.
As shown in figure 3, composite curve road wheel 3 uses arc transition in tooth top position, it is smaller than the transverse tooth thickness of involute sprocket 5
Some, and rounding off.
Existing involute or cycloid are replaced by composite curve, the tooth form of road wheel is completed, processes composite curve row
Walk wheel.
