Sometimes , tooth height of pinion must be revised too, so as to avoid geometrical interference when the quantity of pinion teeth is smaller than 18. This should be noticed when selecting a gear to match the pinion. The number of pinions to be used should be determined according to the driving force\u00a0that the \u00a0system needs.

Our company proposes to use 10.9 grade high-strength bolts, \u00a0and chooses 8.8 and 12.9 grade high-strength bolts for special use. Spring washers can not be used when installing slewing bearing. The size of plain washer must meet the \u00a0requirements of GB\/T97.l-1985 and GB\/T97.2-1985, and should be treated by hardening and \u00a0tempering. The clamping length of the bolt must be greater than or equal to 5d (d is the nominal \u00a0diameter of bolt). \u00a0When the bolt is being tightened on seat frame, a certain pre-tightening force \u00a0should be guaranteed and it is generally 0.7 times of the yield limit of the bolt.<\/p>\n<p>Note: \u00a0(1) When the bolt size does not meet GB\/T5782-2000 or GB\/ T5783-2000, the value in the
