Description
Technical field
The present invention relates to electromechanical equipment related fieldss, and in particular to a kind of adjustable rack gear.
Background technique
Electromechanical equipment is widely used in daily life, and needs to use a large amount of gear in electromechanical equipment and rack gear is matched
It closing and uses, middle gear can be divided into spur gear and helical gear, and wherein the profile contact line of spur gear is the straight line parallel with axis,
A pair of tooth profile enters engagement along the facewidth simultaneously or exits engagement, easily causes impact and noise, transmission stability is poor.It is helical gear
Path of contact is oblique line, and helical gear is stronger than Spur Gear Driving ability, noise is small, stability of rotation.And but relative to spur gear, it is axial to divide
Power be for gear drive it is harmful, it increases the frictional force between device, and device is made to be prone to wear out or damage.
The rack gear that gear matches therewith is the special gear that a kind of tooth is distributed on bar shape, and rack gear also divides spur rack
And diagonal-cut rack, it is used respectively with straight spur gear and helical gears pairing, rotation can be become moving along a straight line, straight-tooth
The tooth trace of item is perpendicular to the straight line of the direction of motion of tooth, and the flank profil of rack gear non-involute for straight line is equivalent to reference circle half
Diameter is infinitely great roller gear.
Existing rack structure is simple, has a single function, and can only match spur rack or helical rack, but in actual production process
In, service condition is complicated, needs that spur gear and helical gear is selected to use according to the actual situation, common rack gear can not be adjusted, nothing
