Straight Gear, Pressure Angle 20°, Module 0.5 (Part Numbers)

Product Overview
A gear is a product with teeth added around the circumference of a drive wheel. Gear transmission mechanisms are widely used for transmitting rotational motion, rotational speed, and rotational direction.
Product Feature
Feature 1: Spur gears can provide high transmission power, and the instantaneous transmission ratio is stable, making them suitable for high-torque transmission and conveying.
Feature 2: Spur gears have a fixed center distance and long service life, making them suitable for compact and highly reliable mechanisms.
Feature 3: MISUMI brand economy spur gears feature high-precision tooth profiles, with a precision grade of GB/T 10095-2008 Grade 8; shaft hole diameter tolerance is H7.
Feature 4: Characteristics of Gear Mechanisms
 
Advantages:
(1) No transmission delay, not prone to skipping or slipping teeth
(2) Relatively free change of transmission direction
(3) Relatively free adjustment of transmission speed
(4) Suitable for high-power transmission, as well as high-load and high-torque transmission
(5) Less affected by temperature, humidity, or oily environments
(6) Suitable for compact space designs
Disadvantages:
(1) Prone to noise
(2) Lubricating oil required for maintenance
(3) Safety protection devices required

Example of Use
MISUMI Spur Gear Use Case■Organization Name
Double Speed Double Stroke Mechanism

■ Mechanism Function
1. After the cylinder extends, the spur gear rotates and extends above the fixed rack.
After it rotates, the rack on the moving side extends.

■Function of Spur Gears
1. By clamping the pinion between the fixed rack and the moving rack, you can obtain the cylinder stroke plus the rotational circumference of the gear on the fixed rack, effectively doubling the movement distance of the cylinder stroke.

For detailed information, click Double Speed Double Stroke Mechanism.
Precautions
(1) If there are requirements for rust prevention, give priority to products made of SUS304.
(2) When gears are used together, there will be backlash. The gear position relationship needs to be adjusted according to the on-site assembly situation to achieve optimal performance.
(3) For shaft hole specifications, when selecting the non-threaded type, the fixing screws are not included.
(4) The positional relationship between the keyway and the gear teeth is not fixed.
