Spiral Bevel Gear For 100 Angle Grinder 90° Spatial Direction Change

Spiral Bevel Gear For 100 Angle Grinder 90° Spatial Direction Change

I. Basic Transmission Logic —— Spatial Direction Change and Speed Increase
1.Power Transmission: The rotational torque output by the angle grinder motor is transmitted to the driven large spiral bevel gear (connected to the grinding disc shaft) through the tooth surface meshing via the driving small spiral bevel gear (connected to the motor shaft). The axes of the two gears are perpendicular at 90°, achieving the spatial direction change of power from the horizontal direction of the motor to the vertical direction of the grinding disc and driving the grinding disc to rotate.
2.Speed - increasing Principle: Utilizing the characteristic of “the small gear driving the large gear to accelerate”, the motor speed is increased, enabling the grinding disc to reach a high speed of 8000 - 12000 r/min, meeting the requirement for high linear speed in cutting and grinding of the angle grinder.

II. Coordination with the Angle Grinder —— Ensuring Grinding Efficiency and Precision
1.Efficient Grinding: The spiral bevel gears have a large meshing contact area and stable transmission, and can stably transmit high torque, allowing the grinding disc to continuously rotate at a high speed. Through the “cutting - grinding” action of abrasive grains, rapid material removal is achieved.
2.Precision Control: The gear tooth profile has high precision, ensuring transmission synchronization, making the rotation runout of the grinding disc small, avoiding the occurrence of “chatter marks” and “deflected cutting” during grinding/cutting, and improving the processing precision.

III. Key Design —— Adapting to the Working Conditions of the Angle Grinder
1.Material and Heat Treatment: 20CrMnTi alloy steel is commonly used. After carburizing, quenching + grinding, the tooth surface hardness reaches HRC58 - 62, which is wear - resistant and impact - resistant, and can withstand the working conditions of high - frequency start - stop and heavy - load grinding of the angle grinder.
2.Installation and Clearance: Through taper fit + keyway positioning, the coaxiality of the gear with the motor shaft and the grinding disc shaft is ensured, and the axial runout is ≤ 0.05mm; and the meshing clearance is adjusted with shims, etc., to balance the transmission efficiency and noise.

This set of spiral bevel gears is the “power core hub” of the 100 angle grinder: it transmits the motor power through 90° spatial direction change, and realizes speed increase by using the small gear to drive the large gear, enabling the grinding disc to reach the high speed for efficient grinding; with high - strength materials and high - precision design, it ensures the stability and precision of the angle grinder during cutting and grinding operations, supporting the surface treatment needs in scenarios such as metal processing and stone treatment.
