  • HW series straight profile toroidal worm reducer
I. Overview
    HW type straight profile toroidal worm reducer (JB/T7936-1999) is called straight profile toroidal worm (also known as spherical worm) because of the toroidal worm pair adopted, and the tooth profile of the worm axial section is a straight line. , Same as other kinds of worm reducers, it is a spatial cross-shaft transmission, with high load carrying capacity and transmission efficiency, suitable for heavy load, high power, high torque transmission, such as metallurgy, mining, lifting, transportation, petroleum, chemical industry , Construction and other machinery
Reduced transmission of equipment.Including HWT and HWB two types.
    Working conditions: the input and output shaft staggered angle is 90*, the worm speed does not exceed 1500r'/min, the worm's mid-plane indexing circle sliding speed does not exceed 16m/sl, the worm shaft can run in both forward and reverse directions. The working environment temperature is -40 —40°C.When the working environment temperature is below 0°C, the lubricating oil is heated to above 0°C before starting, or lubricating oil with a low freezing point is used; when it is higher than 40°C, cooling measures are taken.
