WHSOverview of worm gear reducer
WHSWorm gear reducerIn line with the Ministry of Standards JB2318-79, circular cylindrical worm drive, also called curved cylindrical worm drive, the tooth profile is a convex-concave conjugate type, in which the worm is concave, the worm wheel is convex, and the worm tooth profile is arc-shaped , The code name is ZC worm. WHS Worm GearReducerThe arc-tooth worm gear reducer has the advantages of large carrying capacity, high transmission efficiency, reliable use, and long life. It can be applied to the reduction transmission of machinery and equipment in various industries such as metallurgy, mining, lifting, transportation, chemical industry, construction, etc.
WHSThe characteristics of worm gear reducer and its scope of application
WHS worm gear reducer has the characteristics of large carrying capacity, high transmission efficiency, large output torque, stable operation, long life, and small size. It is widely used in metallurgy, mining, lifting, chemical, construction and other industries.
The worm shaft of the WHS worm gear reducer can run in both forward and reverse directions, the input speed does not exceed 1500r/min, and the working environment temperature is -40-40°C.When the working environment temperature is lower than 0°C, the lubricating oil must be heated to above 0°C before starting; when the working environment temperature is higher than 40°C, cooling measures must be taken.

WHS worm gear reducer assembly form
Use Roman numerals Ⅰ, Ⅱ, Ⅲ... to indicate, add "F" after the fan
The structure of this machine is single-stage transmission, including the following four types:
a, WHT universal type
b, WHS worm in the down type
c. WHS worm on top type
d, WHS worm in side type
The "W, H, T, X, S, C" in the model are the Chinese pinyin of "worm, arc, pass, lower, upper, side" respectively. The prefixes are combined as follows: WHT-Worm can be under the worm wheel, The general-purpose arc-tooth cylindrical worm reducer on the upper and the side; WHS-the arc-tooth cylindrical worm reducer with the worm below the worm wheel; WHS-the arc-tooth cylindrical worm reducer with the worm above the worm wheel; WHS- Circular arc tooth cylindrical worm reducer with the worm on the side of the worm wheel
WHSWorm gear reducer installation
The irrigation of cement slurry should be dense, without bubbles, voids and other defects.Reduction ratio: the ratio of the input speed to the output speed.Number of stages: the number of sets of planetary gears.Generally, it can reach the third level, and the efficiency will be reduced.Full load efficiency: Under load conditions (the output torque is stopped by failure), the transmission efficiency of the WHS worm gear reducer.Working life: The accumulative working time of the reducer under rated load and rated input speed.Rated torque: the torque for long-term operation allowed by the rated life.When the output speed is 100 rpm, the life of the reducer is the average life. When this value is exceeded, the average life of the reducer will be reduced.The reducer malfunctions when the output torque exceeds twice.
The eyebolts on the WHS worm gear reducer can only be used for lifting the reducer.
When installing the reducer on the foundation, the elevation of the installation center line of the reducer, the levelness and the relevant dimensions of the connected parts should be calibrated.The concentricity of the calibrated moving shaft should not exceed the allowable range of the coupling.
When the WHS worm gear reducer is calibrated, it can be carried out with steel spacers or cast iron spacers. The height of the spacers does not exceed three blocks, and it can also be carried out with a contract iron, but the reducer should be replaced with flat spacers after calibration.
It is not allowed to use direct hammering method when adding couplings, belt pulleys, sprocket and other coupling parts to the output shaft of the WHS worm gear reducer, because the output shaft structure of the reducer cannot withstand the axial hammering force, it can be used Screw the screw into the screw hole at the shaft end and press the coupling piece.
The shaft diameters of the output shaft and the input shaft are matched with GB1568-79.
The configuration of the cushion block should avoid causing deformation of the machine body, and should be arranged symmetrically on both sides of the foundation bolts, and the mutual distance can be enough to allow the water slurry to circulate freely during irrigation.
