product description

The CNA series shell-to-hydrostatic drive device is an ideal deceleration component in the transmission mechanism. Due to its compact structure, these reducers can also be used in places where the installation environment is extremely difficult. The product adopts international transmission technology and design experience and advanced processing methods, effectively ensuring high load-bearing capacity and operational reliability.

The reducer designed not only meets the Rexroth series standards, but can also be designed to provide alternative products similar to Brevini, Japan, Teijin, Fujitsu, KYB, Fairfield or Sauer. As the company has strong innovative design capabilities, we can provide customers with consulting services and reasonable selection, in order to find the most suitable product solutions for customers.

According to the design requirements, the reducer can not only be connected with Rexroth type quantitative or variable hydraulic motors, but also can be matched with other hydraulic motors if necessary. The input end of the reducer can be equipped with a multi-disc parking brake with coil spring brake and hydraulic release as required. The static braking torque of the brake is compatible with the input torque of the equipped hydraulic motor (generally greater than 1.5 times). For some reducers, mechanical disengagement clutches can also be installed according to requirements, so that they can be pulled by other equipment in an emergency, which can prevent hydraulic components from being damaged.

This type of reducer has been widely used in the main and auxiliary hoisting and crawler driving of rotary drilling rigs, the main and auxiliary, luffing hoisting and crawler driving of crawler cranes, the crawler driving of various drilling rigs, road rollers, and high-altitude operation wheel drives. The power head and walking drive of iron chuang machine and coal mine roadheader, the drive mechanism of ship crane, terminal and container crane. The products were mainly exported to Europe, North America and other countries before 2008, and are now used in batches in major domestic enterprises. (Note: The specific specific speed of the product is different, and the length is slightly different. Please contact our company's technical staff.)
