Analysis of Hard Tooth Surface Reduction: Four Major Series of Reduction Motors
Hard tooth surface reduction motor is a type of reduction motor that combines hard tooth surface gear technology. It has the characteristics of high load-bearing capacity, strong wear resistance, and long service life, and is widely used in industrial scenarios with heavy loads, high impact, or continuous operation. The following is a detailed introduction about the hard tooth surface reduction motor:
1、 Basic concepts
definition:
A hard tooth surface reduction motor is integrated with an electric motor (AC or DC) and a hard tooth surface gear reducer, which reduces output speed and increases torque through gear transmission.
Core features:
Hard tooth gear: The gear surface is treated with carburizing, quenching, nitriding and other processes, and the hardness can reach HRC58-62, with excellent wear and fatigue resistance.
High transmission efficiency: The gear precision is high (6-8 levels), and the transmission efficiency can reach over 95%.
Compact structure: Modular design, small size, light weight, suitable for space limited occasions.
2、 Structure and Composition
motor
Common types: three-phase asynchronous motor, permanent magnet synchronous motor (high-efficiency and energy-saving).
Power range: 0.12kW~200kW, suitable for different load requirements.
reducer
Gear types: helical gear, planetary gear, worm gear (some hard tooth surface designs).
Reduction stages: single-stage, two-stage, or multi-stage reduction, with a wide range of reduction ratios (such as 5-2000:1).
Hard tooth surface gear technology
Materials: Alloy steels such as 20CrMnTi and 20CrMo.
Process: carburizing and quenching → grinding teeth → surface hardening, ensuring high hardness of the tooth surface and high toughness of the tooth core.
Attachment configuration
Optional encoders, brakes, forced cooling fans, etc. are available to meet special working conditions.
Core advantages:
High load-bearing capacity
Hard toothed gears can withstand heavy loads and impact loads, making them suitable for harsh working conditions such as mining and metallurgy.
long-life
Excellent wear resistance, with a lifespan 3-5 times longer than ordinary soft tooth gears.
Low noise
Precision gear grinding process reduces meshing vibration, and the operating noise is ≤ 65dB (A).
Efficient and energy-saving
High transmission efficiency (>95%), reducing energy loss.
