Bevel Gears
Bevel gears are a type of gear that are used to transmit power between two shafts that intersect at an angle. They have teeth that are cut on a conical surface, and they can be classified into different types depending on the shape and arrangement of the teeth, such as straight, spiral, zerol, hypoid, and miter bevel gears. Some of the advantages and disadvantages of bevel gears are:
- Advantages:
- They can change the direction of rotation and the operating angle between the shafts
- They can achieve high speed reduction and high torque transmission with a single pair of gears
- They can provide self-locking operation, which prevents the driven gear from driving the driving gear
- They can be made from various materials, such as steel, cast iron, bronze, plastic, etc.
- Disadvantages:
- They are difficult to manufacture and assemble, as they require precise machining and alignment of the shafts.
- They have low efficiency and high wear, as they generate a lot of friction and heat between the teeth.
- They have limited gear ratio, as they are constrained by the strength and size of the teeth.
- They produce axial thrust and radial forces on the shafts and bearings, which require special.
