How to guarantee the Quality of gears and parts?
We are ISO 9001:2008 certified firm. we have the integrated system for industrial parts quality control. We have IQC (incoming quality control), IPQCS (in process quality control section), FQC (final quality control) and OQC (out-going quality control) to control each process of industrial parts prodution.
Bevel gears are used to change the direction of rotation of the shaft. Bevel gears have spur, spiral or hypoid shape teeth. Straight teeth have similar characteristics to spur gears and have a great influence when meshing. Similar to a spur gear, a straight bevel gear has a normal gear ratio range of 3:2 to 5:1.
The helical teeth operate the same as the helical gears. They produce less vibration and noise than straight teeth. The right side of the spiral bevel is the outer half of the tooth, inclined to travel clockwise from the axis plane. The left hand of the spiral bevel travels counterclockwise. The normal gear ratio range is 3:2 to 4:1.
A hypoid gear is a helical gear whose shape is a rotating hyperboloid rather than a conical shape. The hypoid gear places the pinion on the ring gear or crown wheel. This allows the pinion to be larger in diameter and provides more contact area.
Pinions and gears are usually always opposite, and the helix angle of the pinion is usually greater than the angle of the gear. Hypoid gears are used in powertrain systems due to their large gear ratios. The normal gear ratio range is 10:1 to 200:1.
