The cement ball mill is more important in cement equipment. Its performance directly affects the quality of cement, so in the process of work, the requirements of cement ball mills are strict, in which the manufacturing of transmission components must be met to meet the following requirements. Good improvement efficiency.
(1) Large, small gear tooth side gap is not less than 1.4 mm, no more than 2.18 mm;
(2) size gear tooth contact spot is not less than 50% direction in the direction of teeth along the gear direction No less than 40%, and tend to the middle of the tooth side.
(3) The radial transmission of the ring gear does not exceed 0.25 mm per meter, and the end circle of the ring gear does not exceed 0.35 mm per meter;
(4) ring gear end face and the cylinder flange It should be attached, if there is a gap no more than 0.15 mm, the gap of the pitched ring gear is not more than 0.1 mm, and the specific deviation is 0.005 modulus.
(5) For gear processors, detect tooth precision, tooth surface hardness, deep depth, after assembly, contact accuracy, teeth, etc., and detailed inspection records.
(6) Big gentle material: ZG40CR.
(7) Hair Material: Forgings 40Cr, Temperature Stripping HB \u003d 227 \u003d 226;
(8) Non-destructive detection after rough processing, in line with the requirements of the product .
(9) Positioning pre-assembled and positioning mounting marks in the manufacturer and cylinders.
The production of cement ball mills must be carried out in accordance with professional configuration, so you can use safer production.
