Our Products
We are leaders in the market for providing best range of Worm Gears, Helical Gears, Sprockets, Bevel Gears and Worm Reduction Gear
The specialty of a worm gear and worm wheel is that they provide a large speed ratio but with significant sliding. Another feature being of the worm gear is that most of the designs are non reversible.
Worm Gears are suited for
Although worm gears can be standardized for high precision, they have their own limitations. Worm Gears can be at best considered for average precision meshes, but for works of high precision they have to be selected with care. They are probably the apt choice for a combination of high velocity ratio and right angle drive. Excellent lubrication should always be ensured in use of worm gears since high sliding requires , lubrication at all times.
Chain drives are used where positive action is required. The velocity is constant to some extent. Power is transmitted, in this case over a shorter distance than in the case of belt or rope drives. Chains are made up of rigid links and of various types. They are classified as:
The wheels over which chain runs are called sprocket wheels. These wheels have projecting teeth which fit the suitable recess in the links of the chain and thus enable a positive drive to be obtained.
The pitch of the chain is defined as the distance between a hinge center of one link to the corresponding hinge center of the adjacent link. The pitch circle diameter of the chain sprocket is the diameter of the circle on which the hinge centers lie, when the chain is wrapped round the sprocket.
Quality:
Sources of errors in manufacturing gears:The gears (gear teeth) are generally made by one of the following two methods:
The various sources of errors in the gear made by reproducing method can be due to
The sources of error when gears are made by generating method are:
Prakash Gears (Prakash Gears)
