Product Description

 

 

Product Description

The K series reducer typically refers to a "right-angle axis helical gear-bevel gear reducer". Its core feature is that the input shaft of the motor and the output shaft of the reducer are at a 90-degree angle.

Key Features and Advantages

1. Right-angle output, changing the direction of power: This is the most fundamental advantage of the K series. It can change the direction of the power transmitted from the motor by 90 degrees, greatly optimizing the structural layout of the equipment and saving the overall space.

2. Sturdy structure and strong bearing capacity: Spiral bevel gears are usually used as the primary transmission. This gear design makes the reducer structure very strong and can withstand large radial loads (forces acting on the output shaft) and impact loads.

3. Diverse forms of output: The output end is usually designed as a solid shaft or a hollow shaft (with locking disk or shrink disk), which is very convenient for direct connection with the working machine (such as sprockets and pulleys) to achieve "shaft-mounted" installation.

4. Higher transmission efficiency: Although the efficiency of bevel gear transmission is slightly lower than that of pure helical gears (R series) of the same level, it is still maintained at a high level (usually >94%).

Main Application Scenarios
 
The right-angle steering and solid structural characteristics of the K series reducer make it an almost irreplaceable first choice in the following scenarios:

1. Material transportation and automated logistics fields
Belt conveyor (driven roller): The hollow output shaft of the reducer can be directly mounted on the drive roller of the conveyor. It has a compact structure and is easy to install, without the need for additional couplings and transmission components (such as chains). 
Plate chain conveyor/chain plate line: Similarly, the driving sprocket of the conveyor can be directly driven.
Scraper conveyor: Common in agriculture, food processing and other industries.
Elevator: Used to lift materials in vertical or inclined directions.

2. Agricultural machinery field
Harvester: drives cutting, conveying and other mechanisms.
Tractor supporting equipment: such as rotary tillers, seeders, etc., need to change the direction of power and withstand the impact of field operations.

3. Engineering machinery and construction equipment
Concrete mixer: drives the mixing tank.
Road construction machinery: such as some auxiliary drive devices in road rollers and pavers.
Mining machinery: The environment is harsh and requires a sturdy and durable drive solution.

4. General industrial equipment
Mixing equipment: When the motor needs to be placed vertically and the mixing shaft is placed horizontally (or vice versa).
Winches: Compact right-angle drives are required to wind wire ropes.
Rubber and plastic machinery: used as auxiliary drive on extruders, calenders and other equipment.

The gear shaft is made of high-strength bearing steel, undergoes quenching and precision machining, and features a strong load-bearing capacity, ensuring smooth transmission.
Precision gears are made from 20CrMnTi low-carbon alloy steel and undergo vacuum carburizing heat treatment, ensuring stable quality and low noise.
