HW type straight profile toroidal worm reducer (JB/T7936-1999), because of the toroidal worm pair used, its worm axial section tooth profile is straight, so it is called straight profile toroidal worm (also known as spherical worm) It is the same as other various worm reducers. It is a space-interlaced shaft drive with high bearing capacity and transmission efficiency. It is suitable for heavy-duty, high-power, high-torque transmission, such as metallurgy, mining, lifting, transportation, petroleum, chemical industry. Deceleration transmission of mechanical equipment such as construction. Including HWT, HWWT, HWB, HWWB type four forms.

Working conditions: the input and output shaft stagger angle is 90 °C; the worm speed does not exceed 1500r/min; the worm intermediate plane indexing circular sliding speed does not exceed 16m/s; the worm shaft can run in the forward and reverse directions; the working environment temperature is -40 °C~40°C. When the working environment temperature is lower than 0 °C, the lubricating oil must be heated above 0 °C before starting, or the lubricating oil with low freezing point; if it is higher than 40 °C, cooling measures must be taken.
