External gear/internal gear, like bevel gears: Internal gears do not cause output shaft direction reversal.
Spur gears or straight-cut gears: Consist of a cylinder or disk with teeth projecting radially, spur gears are simplest.
Helical or "dry fixed" gears:The leading edges of the teeth are not parallel to the axis of rotation, but are set at an angle.
Skew gears: For a "crossed" or "skew" configuration, the gears must have the same pressure angle and normal pitch; however, the helix angle and handedness can be different.
Spiral bevel gears: Manufactured as Gleason types (circular arc with non-constant tooth depth), Oerlikon and Curvex types (circular arc with constant tooth depth), Klingelnberg Cyclo-Palloid (Epicycloide with constant tooth depth) or Klingelnberg Palloid. Spiral bevel gears have the same advantages and disadvantages relative to their straight-cut cousins as helical gears do to spur gears. Straight bevel gears are generally used only at speeds below 5 m/s (1000 ft/min), or, for small gears, 1000 r.p.m
Hypoid gears: This is resemble spiral bevel gears except the shaft axes do not intersect. The pitch surfaces appear conical but, to compensate for the offset shaft, are in fact hyperboloids of revolution.
Crown gears:This is a particular form of bevel gear whose teeth project at right angles to the plane of the wheel; in their orientation the teeth resemble the points on a crown.
Slewing drive: Worm-and-gear sets are a simple and compact way to achieve a high torque, low speed gear ratio.
Rack and pinion: A rack is a toothed bar or rod that can be thought of as a sector gear with an infinitely large radius of curvature.
Usage: Kingrail gears can be used for automobile, trains, vessels,heavy truck, light truck, minibus and other vehicles, wind power, etc.
Kingrail gears advantage:
1.Big capacity: Annual output of 100,000 tons forging parts,1.5 million sets of finishing production capacity
2.Quick production term and serious quality control: the manufacturing period of the mould is usually 4 days and the period for replacement and debugging is only about 1 hour. When each batch of production starts, R&D will conduct test run to check the quality of forging blank. Each set of mould can basically meet the production capacity of 3000-5000 sets of products, which greatly reduces production cost and improves production efficiency.
Cost control: Formed a scale purchasing advantages and price advantages, established a stable raw materials supply channels and more favorable price.
