(1) HWT - worm worm gear casting in the above body and cover of Hindley worm reducer
(2) welded body and cover of Hindley worm reducer worm in the worm gear on type HWWT
(3) HWB - worm worm gear casting in under the body and cover of Hindley worm reducer
(4) welded body and cover of Hindley worm reducer worm in the worm gear under HWWB
HW type of Hindley worm reducer (JB/T7936-1999) for the auxiliary worm, the worm axial section profile is linear, so it (also known as the hourglass worm gear worm), is the same with other kinds of worm reducer, space staggered shaft drive, load capacity and high transmission efficiency, application for the heavy load, large power, large torque transmission, deceleration transmission such as metallurgy, mine, lifting, transportation, petroleum, chemical, construction machinery and equipment. Including HWT, HWWT, HWB, HWWB type four kind of forms.
Working conditions: input, output shaft stagger angle is 90 DEG C; the worm speed not exceeding 1500r/min; worm middle plane dividing circle sliding speed of not more than 16m/s; the worm shaft can be positive, reverse operation; working temperature is -40 ℃ ~40 ℃. When the environment temperature is below 0 ℃, before the start of the lubricating oil must be heated to 0 ℃, or used lubricating oil low freezing point; higher than 40 ℃, the cooling measures must be take.
