采煤机用制动器
摘要：
本实用新型揭示了一种采煤机用制动器，所述制动器安装于采煤机牵引传动装置；所述制动器包括壳体、活塞、第一弹性机构、内摩擦片、外摩擦片、第二弹性机构波形弹簧、花键套；所述壳体设有进油口，外接控制油路；所述活塞设置于壳体中，活塞及壳体之间形成油腔；所述活塞的一端连接所述第一弹性机构，另一端设有相间布置的内摩擦片、外摩擦片；所述内摩擦片、外摩擦片之间设置所述第二弹性机构；内摩擦片连接花键套，花键套连接到采煤机牵引传动装置。本实用新型提出的采煤机用制动器，内外摩擦片能依靠弹簧分开，空转时不摩擦，有效降低了运转温度，避免内外摩擦片烧坏的现象出现，有效解决制动器运转时温度高的问题，提高了采煤机制动可靠性。
摘要（英）：

The utility model discloses a brake for a coal mining machine. The brake is arranged on a traction transmission device of the coal mining machine. The brake comprises a shell, a piston, a first elastic mechanism, an inner friction plate, an outer friction plate, a second elastic mechanism wave spring and a spline sleeve. The shell is provided with an oil inlet and externally connected with a control oil way. The piston is arranged in the shell, and an oil cavity is formed between the piston and the shell. One end of the piston is connected with the first elastic mechanism, the other end of the piston is provided with the inner friction plate and the outer friction plate, and the inner friction plate and the outer friction plate are arranged in a spaced mode. The second elastic mechanism is disposed between the inner friction plate and the outer friction plate. The inner friction plate is connected with the spline sleeve, and the spline sleeve is connected with the traction and transmission device of the coal mining machine. According to the brake for the coal mining machine, the inner friction plate and the outer friction plate are separated through the spring, no friction exists during idling, operation temperature is effectively lowered, the phenomenon that the inner friction plate and the outer friction plate are burnt is prevented, the problem that the temperature of the brake is high during operation is effectively solved, and brake reliability of the coal mining machine is improved.
