GFT220T2

product description:

GFT series compact high-speed shell-rotating reducer is an ideal reduction component in the transmission mechanism. Due to its particularly compact design, this gear unit can be used in extremely difficult installation environments. The product adopts advanced design technology and advanced processing means, which effectively guarantees high carrying capacity and operational reliability.

GFT reducer not only meets the standard of Rexroth type series, but also can be designed to provide alternative products similar to Brevini, Teijin, Fujikoshi, KYB, Fairfield or Sauer according to specific needs. As our 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 the Rexroth type quantitative or variable hydraulic motor. It can also be matched with other hydraulic motors if necessary. The input end of the reducer can be equipped with a multi-disc parking brake with spring brake and hydraulic release as required. The static braking torque of the brake is adapted to the input torque of the hydraulic motor (generally greater than 1.5 times). For some reducers, a mechanical disengager can also be installed according to requirements, so that it can be pulled by other equipment in an emergency. Prevent hydraulic components from being damaged.

This kind of reducer products have been widely used in the main and auxiliary winches and crawler travel drives of rotary drilling rigs. The main and auxiliary, luffing winches and crawler drives of crawler cranes, crawler drives of various drilling rigs, road rollers, aerial work wheel wheel drives, Power head and travel drive of milling machine and coal mine roadheader. Drive mechanism of ship crane, wharf and container crane. The products have not only been used in domestic key users such as Sany Heavy Industry, Xugong Group, and Zoomlion, but also exported to Southeast Asia, India, South Korea, the Netherlands, Russia and other regions and countries.

Product model example:

GFT60T3-B86-A2FE80/61WVZL10 means that the maximum output torque of the reducer is 60KN m, which is used for walking drive. It adopts three-stage planetary reduction, with parking brake, the total transmission ratio is 86, and the hydraulic motor model is A2FE80/61WVZL10.

Product model description:

液压油泵和液压电机是可逆工作的液压附件。将液压油泵输入所有液压油泵，可使其成为液压电机的工作条件；相反，当低速液压电机的主轴轴承由外扭曲距离控制器旋转时，也可以成为液压油泵的工作条件。因为它们具有相同的基本结构元素，封闭的体积和相应的配油机构可以周期性变化。

同一品种的旋转液压电机和液压油泵之间仍存在许多差异。由于液压电机和液压油泵的工作规范不同，其特点要求也不同，液压电机应能正旋转，因此其内部结构对称；旋转液压电机的速度比范围应足够大，特别是对其速度稳定较小。因此，它一般都采用滚珠轴承或负压力滚柱轴承；其次低速档液压马达由于在输入压力油规范下工作中，因而不必具备自吸式式专业能力，但应当的初始密封性，才可以提供必不可少的电动机扭矩。也是由于存在着这类区别，促进回转液压马达和液压油泵结构特征比较相近，但不能可逆工作中。
