Half Ring Girth Gear

Steel Castings for GearsIt is recommended that steel castings for cut gears be purchased on the basis of chemical analysis and that only two types of analysis be used, one for case-hardened gears and the other for both untreated gears and those which are to be hardened and tempered. The steel is to

The herringbone gear is a specially designed double helical gear, with its teeth arranged in a "person" shape. The helical angles on the left and right sides are symmetrical but opposite in direction. This structure endows it with both high load-bearing capacity and smooth transmission characteristi

Gear steels may be divided into two general classes — the plain carbon and the alloy steels. Alloy steels are used to some extent in the industrial field, but heat-treated plain carbon steels are far more common. The use of untreated alloy steels for gears is seldom, if ever, justified, and then, on

Gears come in many different shapes and are widely used. Spur gears are the most common type of gears. They have straight teeth, and are mounted on parallel shafts. Sometimes, many spur gears are used at once to create very large gear reductions. Spur gears are used in Minging excavator，Crush
