GFT550T2

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.

    1.壳体：是减速 机的关键构成构件，它是传动系统整体的底座，应存有充足的硬度跟弯曲刚度，通常用灰口铸铁生产制造。

    对重裁或有冲击性载荷的减速 机，二手减速机也有可能采用球墨铸铁壳体，铸钢件壳体。针轮减速 机将电机的回转数降速到时需的回转数，并获得比较大转矩的设备。减速器是一种相对高精度的机械设备，其目的是降低转速比，提高转矩。针轮减 速机是选用旋轮线针齿齿合、大行星式传动系统基本原理，因此通常也称为大行星旋轮线减速 机。

    2.传动齿轮、轴及滚动轴承组成：这类组成用以饱受切向载荷跟并不大的径向载荷的状况，当径向载荷比较大时。

    应采用角接触球轴承、园锥滚柱轴承或角接触球轴承与推力球轴承的组成构造。针轮减 速机将电机的回转数降速到时需的回转数，并获得比较大转矩的设备。减速器是一种相对高精度的机械设备，其目的是降低转速比，提高转矩。微型减速机是选用旋轮线针齿齿合、大行星式传动系统基本原理，因此通常也称为大行星旋轮线减速 机。GFT550T2
