Cylindrical gears are a common transmission component with various structural forms, and their application scope and characteristics are as follows:

·Ordinary spur cylindrical gears

Ordinary spur gear is the most common gear structure, with its tooth surface parallel to the gear axis. Widely applicable, suitable for situations with low power transmission, such as household appliances, small machinery, etc.

Features:

(1) High transmission efficiency, with an efficiency of over 95%;

(2) High precision requirements, high machining accuracy and tooth profile accuracy requirements;

(3) Long service life, but susceptible to wear and impact.

·Helical cylindrical gear

The tooth surface of helical cylindrical gears is at a certain angle to the gear axis, which has good self centering ability and is suitable for situations with significant changes in working load, such as large machinery, vehicles, etc.

Features:

(1) Capable of withstanding a certain degree of axial and radial loads, with good self centering characteristics;

(2) High transmission efficiency, with an efficiency of over 90%;

(3) The processing difficulty is high, and the accuracy requirement is high.

·Bevel cylindrical gear

Bevel cylindrical gears are an important type of gear, whose tooth surface forms a certain bevel angle with the gear axis. Suitable for transmitting high power and torque, such as ships, heavy machinery, etc.

Features:

(1) Capable of transmitting high power and torque, suitable for heavy load situations;

(2) High transmission efficiency, reaching over 95%;

(3) High requirements for machining accuracy and tooth profile accuracy.
