Pros & Cons of Worm Gear and Bevel Gear

Worm gears are utilized as a part of applications where vast gear reductions, torque, and braking are important. A portion of the greatest highlights of worm drives is that they accomplish high proportions in a single reduction, and have the capacity to deal with shock loads with less noise.
One preferred standpoint that makes worm drives attractive over other gearboxes is that they have relatively few moving parts in high reduction proportions, essentially two shafts, i.e. input and output, which is backed by four bearings.
 
Pros:
 
Ease of support
Low noise properties
Handles expansive reductions
Large shock load capacity
High thermal limit
 
Cons:
 
Moderate Efficiency
Large package in design
Relatively costly to fabricate
 
Bevel Gear
 
Bevel gears are used when the bearing of a shaft’s rotation is to be changed. Bevel gears are generally mounted 90 degrees apart on shafts. However, it can be intended to work at different angles too. The teeth can be spiral, straight or hypoid, on bevel gears. Straight bevel gear teeth and straight spur gear teeth have the same issue – as every tooth draws in, it impacts the corresponding tooth at the same time.
 
Pros:
 
The operating angle can be changed using this gear. The number of teeth differs on each wheel enables mechanical advantage to be changed. By expanding or diminishing the proportion of teeth between the drive and driven wheels, one may change the proportion of turns between the two, implying that the rotational drive and torque of the second wheel can be changed in connection to the first with speed expanding and torque diminishing, or speed diminishing and torque expanding.
 
Cons:
 
One wheel of such gear is intended to work with its corresponding wheel and no other.
Must be unequivocally mounted.
The shafts’ bearings must be equipped with supporting power.
 
Applications of Bevel Gears
 
In marine application, energy sector, cement units, locomotive, steel sector, defense sector, etc, bevel gears are mostly used.
When the speed and load both are small the transmission of power and motion between the two shafts are conducted by bevel gears.
In various automobile applications like vehicle differential drives, hypoid bevel gears are used.
For the key mechanism of hand drill, bevel gears are used.
Spiral bevel gears are used in sewing machines.
