Bevel Pinion Set

Bevel pinion:

The standard definition of a Bevel Gear is a cone-shaped gear which transmits power between 2 intersecting axels.

Bevel gears can be generally classified by their manufacturing methods, namely the Gleason method and Klingelnberg method, which each have differing teeth shapes, and presently most gears use the Gleason method.

The optimum transmission ratio varies in the range 1,2,3,4,5.

Some extreme cases this ratio can reach up to 10.

We can make centre bore and keyway as requirement.

Bevel gears are used extensively in a wide variety of industries and mechanical operations due to the most important advantage they offer: smooth and low-noise power transmission between non-parallel shafts at almost any angle or speed. 

A pair of meshing helical gears driven by parallel shafts, with equal helix angles and opposite rotation directions. degree.

For a pair of meshing helical gears (also called helical gear drive) driven by staggered shafts, the shaft intersection angle is equal to the algebraic sum of the known two helix angles (the shaft intersection angle is the acute angle between the two shafts; the two helix angles can be of the same or different rotation directions; the rotation directions are different, and the positive and negative helix angles are different).

Because helical gears enter into mesh along the tooth width at the same time, impact vibration noise is generated and the transmission is unstable. Helical cylindrical gear transmission is superior to straight gear transmission, and can be used for high speed and heavy load with close center distance. The larger the helix angle of the helical gear circle, the greater the overlap, which is more conducive to smooth movement and reduce noise. Everything has two sides. Although increasing the helix angle brings many advantages, the axial force generated during operation also increases. Therefore, the size should depend on the quality requirements and processing accuracy of the work. Generally, 8-25 is taken. If there are special requirements for noise, the larger value can be taken according to the situation. The calculation formula of spur gear can be directly applied to the end face of helical gear in calculation because a pair of helical gear transmission is equivalent to a pair of spur gear transmission on the end plane.
