Plastic Bevel Gears

Plastic Bevel Gears

This type of gear has a conical shape with straight or spiral-cut teeth. Plastic bevel gears transfer motion between two axles that are intersecting, changing the rotation axis. These types of gear are mostly utilized in power tools and automotive applications. On all designs, the spiral cut version can be smoother and less noisy than other designs.

The positive characteristics of plastic bevel gear include being lightweight, non-rusting, quiet, injection molding enabling low cost and large production, and able to operate without lubrication by mating with metal gears. On the other hand, low strength, tendency to hold heat, large dimensional change including backlash compared to metal, etc., are some of the points requiring caution. The degree of dimensional changes that occur with plastic bevel gear depends on the ability to resist temperature change, moisture absorption rate, and chemical resistance.

As far as the applications of plastic bevel gear set, they are used in varying industries such as food production machines, consumer electronics, chemical, toy, and medical equipment industries.

Plastic Bevel Gears Specification

●The teeth on bevel gears can be straight, spiral, or hypoid. Straight bevel gear teeth have the same problem as straight spur gear teeth -- as each tooth engages, it impacts the corresponding tooth all at once.

●Just like with spur gears, the solution to this problem is to curve the gear teeth. These spiral teeth engage like helical teeth: the contact starts at one end of the gear and progressively spreads across the whole tooth.

●Offers ODM & OEM services.

Plastic Bevel Gears Advantages

1. Cost-Effective: Plastic bevel gears are generally more cost-effective compared to their metal counterparts. The production process for plastic gears is often less expensive, making them a more economical choice.

2. Lightweight: Plastic bevel gears are lightweight, which is beneficial in applications where weight reduction is desired. Their low mass results in reduced inertia, allowing for smoother and more efficient operation.

3. Corrosion Resistance: Unlike metal gears, plastic bevel gears are corrosion-resistant. This makes them suitable for use in environments where exposure to moisture, chemicals, or other corrosive substances is a concern.

4. Low Noise and Vibration: Plastic gears tend to produce less noise and vibration compared to metal gears. The inherent dampening properties of plastic help reduce noise levels during gear operation, resulting in quieter machinery.

5. Self-Lubricating: Many plastic materials used for bevel gears have self-lubricating properties. This eliminates or reduces the need for external lubrication, simplifying maintenance requirements and reducing the risk of lubricant contamination.

6. Design Flexibility: Plastic bevel gears offer greater design flexibility compared to metal gears. Plastic materials can be molded into complex shapes, allowing for custom gear designs to meet specific application requirements.

Plastic Bevel Gears Applications

Although the plastic bevel gear has to wear resistance and silence on the rotation, its strength is less than the steel gear; thus, it is suitable for the drive system of office automation types of equipment, the loader of electric goods, and toys.
