Parameter introduction:
Horizontal reducer-mining reducer type series mining vertical hard tooth surface reducer
Category: B/reducer
Installation mechanism type: horizontal
Model: Type series mining vertical hard tooth surface reducer
The reducer has the characteristics of large carrying capacity, high transmission efficiency, low noise, small size, light weight and long life. It is suitable for transmission devices where the input shaft and output shaft are arranged in a vertical direction, such as scraper conveyors, belt conveyors and various transportation machinery. It can also be used in metallurgy, mining, chemical industry, cement, construction
and light industry. , energy and other general machinery transmission mechanisms.

Reducer performance characteristics:
Main parameters such as center distance and nominal transmission ratio have been optimized and designed, and the main parts have good interchangeability.
.The gears are made of high-quality alloy steel through carburization and quenching, and the tooth surface hardness is up to 100%.
3. Small size, light weight, high precision, large load-bearing capacity, high efficiency, long life, high reliability, smooth transmission and low noise.
The reducer consists of a pair of arc bevel gears, a pair of helical gears, and a pair of spur gears to form a three-stage reduction. The total reduction ratio is:. The bearings of the first, second and third axes are single-row tapered roller bearings, and the fourth axis is a double-row radial spherical roller bearing. The locking nut on the first shaft is used to fix the bearing and ensure that the axial clearance of the bearing is .~.mm. The axial clearance of the second, third and fourth bearings is guaranteed by adjusting pads. Among them, the second and third shafts The axial clearance of the bearing is .~.mm, and the axial clearance of the four-axis bearing is .~.mm. During assembly, the axial position of the circular arc bevel gear must be adjusted appropriately to ensure meshing backlash and contact spots. The axial displacement of the circular arc bevel gear is adjusted by adjusting the nut, and the large arc bevel gear is adjusted by adjusting the shaft axis through the adjusting pad. direction position. In order to achieve better meshing accuracy, the meshing backlash of a pair of adjusted circular arc bevel gears is not less than .mm, and the contact spots along the tooth length and tooth height directions are not less than .
When assembling the reducer, adjusting the contact area and tooth side clearance is a relatively detailed task. The adjustment should be done according to regulations, carefully and responsibly
to ensure the correct meshing of the gears to extend the time Use of gears.
