The plane-enveloped toroidal worm drive is divided into two types: plane primary envelope and plane secondary envelope. Compared with cylindrical worms, the toroidal worm pair has a larger number of working teeth at the same time, which has a large bearing capacity, high transmission efficiency and long service life. Especially suitable for heavy-duty power transmission devices.

    TP series plane enveloping toroidal worm reducer (JB/T9051-1999) is a plane one-time enveloping worm drive, including three types of TPU, TPS, and TPA, suitable for metallurgy, mining, lifting, transportation, construction, petroleum , Chemical industry, aerospace, navigation equipment or precision transmission reduction transmission.

    工作条件：蜗杆转速不超过1500r/min，工作环境温度为-40℃-40℃；当工作环境温度低于0℃时，起动前润滑油必须加温到0℃以上。
