Study on the Strength Design for Steel Hourglass Worm Pairs of Track Tension Adjustor on Special Vehicles

摘要

This study analyzed the difference between the steel worm gear in the worm type track regulator and the commonly power hourglass worm.And a strength design method of steel worm gear pair in the track regulator was presented based on the design method of hourglass worm gear:According to the condition of manual adjustment,the strength design of the worm gear pair worm material is tin bronze material,select primary center distance a1,And then according to the difference on the carrying capacity the steel worm gear and tin-bronze worm gear,correct primary center distance a1,Finally check the contact strength of tooth surface when locking condition.
