T815通井机B型取力器的改进

Improvement of power take off on Model T815 tractor hoist.

针对T8 15型通井机取力器结构不合理、取力不足 ,以及取力方式是从离合器后压盘钢片取力而造成启动机及飞轮大齿圈损坏的问题 ,对这种取力器的结构和取力方式进行了改进。改进后的取力器是由离合器输出轴上取力 ,取力功率从原为主机功率的 6 0 %增至 90 %,使通井机滚筒输出扭矩从 6 6 0kN·m增至 10 10kN·m ,提高了设备的载荷能力。此外 ,通井机上井后 ,主机不用熄火就可随时挂合和摘开取力器 ,这不仅节省了时间 ,而且还避免了发动机带载荷启动工况 ,降低了设备故障率 ,经济效益显著。

In the light of the disadvantages of the power take off on Model T815 tractor hoist, an improvement on the structure and operating mode of the power take off is made. After improvement, the power is taken off from the output shaft of the clutch, therefore 90% of the power of the motor can be taken off, and the torque output of the drumworks is increased from 660kN·m to 1010kN·m. The load capacity of the tractor hoist is thereby improved.
