Characteristics of cast iron worm gear reducer

The basic structure of worm gear reducer is mainly composed of transmission parts, worm gear, shaft, bearing, box and its accessories. It can be divided into three basic structural parts: box, worm gear and worm, bearing and shaft combination. The box is the base of all accessories in the worm gear reducer. It is an important accessory to support and fix the shafting components, ensure the correct relative position of the transmission accessories and support the load acting on the reducer. The worm gear is mainly used to transmit the motion and power between the two staggered shafts, and the bearing and shaft are mainly used to transmit power, operate and improve efficiency.
The worm gear reducer is developed on the basis of WD reducer. The worm is made of 45# high-quality steel after heat treatment. The worm gear is cast with tin bronze. It has good wear resistance, especially in the bearing capacity. It is mainly suitable for the deceleration transmission of various mechanical equipment such as plastics, metallurgy, beverage, mining, lifting transportation, chemical construction and so on.
The worm gear reducer has stable transmission, low vibration, impact and noise, large reduction ratio and wide universality. It can be used together with various mechanical equipment.
The meshing friction loss between worm tooth and worm gear tooth surface is large, so the transmission efficiency is lower than that of gear, easy to heat and high temperature.
Higher requirements for lubrication and cooling.
It can obtain large transmission ratio with single-stage transmission and compact structure. Most types of reducers have good self-locking, and can save braking devices for mechanical equipment with braking requirements.
The box type includes basic type (the box body is vertical or horizontal structure with baseboard) and universal type (the box body is rectangular, with fixed screw holes on many sides, without baseboard or with baseboard)
There are two connection modes of input shaft of cast iron worm gear reducer: basic type (single input shaft and double input shaft) and with motor flange.
The position direction of the output and input shaft has the input shaft down and up; Output axial up and down; Input axial up and down.
Good compatibility, worm gears and worms are manufactured according to national standards, and standard parts are used for bearings and oil seals.
Two or three reducers can be used to form a multi-stage reducer to obtain a great transmission ratio.
