Product details

GB420 / 30 scraper conveyor adopts JS-30 type reducer , which is a three-stage reduction, involute gear transmission. The total drive is 22.24 The *** stage is an arc bevel gear, the second stage is a cylindrical helical gear, and the third stage is a cylindrical spur gear. See the table for the technical parameters of each gear

    The structure of this reducer is greatly improved compared with the general mining conical and cylindrical gear reducer. A total of *** shafts adopt a set of double-row radial spherical roller bearings and two sets of single-row radial ball bearings. The axial force generated when the arc bevel gear rotates is borne by two sets of single-row radial ball bearings. Double row radial ball roller bearings are lubricated by splash. Two sets of single-row radial thrust ball bearings are lubricated with No. sodium base grease. The axial arrangement and axial clearance of the shaft arc bevel gear are guaranteed by adjusting the adjustment pads at both ends of the single-row radial thrust bearing.

    The axial clearance of the second shaft is ensured by adjusting the adjustment pads on both sides of the fixed-end bearing. The other bearing is in a free state in the axial direction. Compared with the old structure, it proves that this structure improves the lubrication conditions of the two bearings, improves the contact accuracy of the arc bevel gear, and prolongs the service life of the bevel gear.

    Axial clearance of each shaft of the reducer :

    *** Axis: 0.06 to 0.08mm

    Second axis: 0.08 0.15mm

    Third axis: 0.20 to 0.30mm

    Fourth axis: 0.20 to 0.35mm

    The box of the reducer is symmetrical up and down, to meet the different needs of left and right work underground. When changing the left and right working surfaces, an air plug must be installed on the upper cover and an oil plug must be installed on the lower cover.

    The reducer uses 150 # extreme pressure gear oil or 22 # hyperbolic gear oil to lubricate the gear. The injection amount is the width of the submerged large bevel gear.
