What Is The Difference Between Straight Bevel Gears And Crown Bevel Gears?

Q: What are Crown/Spiral Bevel Gears?

Crown gear has helical teeth that resemble the spiral form where the spinning shaft is curved at 90 degrees. They are mainly known for their total efficiency and produce less vibration and noise. These gears are mainly used in cement factories, sugar mills, mineral plants, mining, and the automobile industry.

Gears are the most commonly used elements to transmit mechanical power in the form of rotational form. Four main types of gear, namely spur gear, worm gear, helical gear, and bevel, are commonly used in various applications.

Bevel gears are the axis of two shafts inclined at 90 degrees with each other used for high-speed applications. These gears are known for their noise reduction, smooth operations, and provides high torque. Bevels are the best choice for industrial purposes because of their cost efficiency and low maintenance.

There are two types of bevel, crown and straight bevel, which we have discussed in detail below. We have also mentioned the difference between them for your better understanding.

What Are Crown/Spiral Bevel Gears?

Crown gear has helical teeth that resemble the spiral form where the spinning shaft is curved at 90 degrees. They are mainly known for their total efficiency and produce less vibration and noise. These gears are mainly used in cement factories, sugar mills, mineral plants, mining, and the automobile industry.

What Is Meant By Straight Gears?

Following its name, straight gears have straight teeth and a conical-shaped axis. These are the most common and simplest bevel type of gear that shares the properties of spur gears. Crown bevel gear manufacturer provides gears for food canning equipment, food packaging, lawn and gardening equipment, fluid control valves, and many more.

Difference Between Straight Bevel Gears And Crown/Spiral Gears

Both gears are used in high-speed operations but contain some differences that impact their operations. You will get to know about all the differences between straight gears and crown or spiral gears to choose the better option.

Straight Gears	Crown/Spiral Gears
True to its name, teeth are straight and cut along the axis in a cone shape.	It has spiral-shaped cutting teeth forming the spiral curve on the pitch cone.
The teeth of mating fears come in sudden contact, and the line of light is equal to the face width of the teeth.	The engagement of mating gears starts with a point and gradually forms a line.
Due to sudden contact, the teeth always shock the mechanism and create noise.	Spiral teeth cutting impacts less shock loading and creates less noise.
The operation is not smooth due to shock loading.	Crown gears also provide smooth operation due to gradual movement.
It exerts less thrust force on the bearings that hold the shafts.	It exerts more thrust force on bearings as compared to a straight bevel gear.
Straight gears are simple and thus cheaper to manufacture.	Due to its complicated design, the manufacturing cost is higher.

Conclusion

These are the differences between the straight gears and the crown/spiral gears that will help you to choose according to your need. Gears manufactures in Punjab Ludhiana provide world-class, high-quality gears for various industries. You can find them online, order the gears of your choice for your business, and get the ultimate customer care service simultaneously.
