Helical Gears
S M Gears Private Limited manufacturers Helical Gears. Helical gears are cylindrical gears that offer less vibration and larger contact ratio as compared to spur gears. The slanted tooth traces of helical gears help in transmitting large force. The one end of the tooth makes contact, and it spreads gradually with the rotation of the gear. Both teeth engage fully in the total engagement stage.
When they use a pair of these gears, the helix hand is always in the opposite, but the helix angle is the same. Due to the twist of the teeth, the production process of these gears is quite difficult.
If the angle of the teeth is perfect, then these gears can be mounted on perpendicular shafts also. You need to change the rotation angle to 90 degrees obviously. Contrary to spur gears, these gears can produce an axial thrust force. Therefore, you need thrust bearings so that the force can be absorbed. It can also be reduced by using a combination of right hand and left-hand helical gears. Helical gears are preferred by automobile industry in the automotive transmission process. Smooth operations can be achieved because of the gradual engagement. In is the reason; they are used in almost all car companies.
