These problems were all solution under the help of my teacher and classmates, because the entire transmission system requests the transmission quite is big, therefore used the structure to be compact, velocity ratio big worm gear worm drive; regarding two kind of different working speeds, used has dialed forks with the twin gear combination realizes between the different speed transformation; regarding the screw tap break, the decayed teeth phenomenon solution is in attacks in the refuse silk to establish the friction disk transmission, may solve this problem well using the friction disk transmission characteristic, now the Dragon Gate type taper has been basic designed, its performance has been waiting for the production practice the confirmation.

这些问题在老师和同学们的帮助下都已基本解决，由于整个传动机构所要求的传动比较大，故采用了结构紧凑，传动比大的蜗轮蜗杆传动；对于两种不同的工作速度，采用了拨叉和双联齿轮的组合来实现不同速度之间的转换；对于丝锥断裂，烂牙现象的解决办法是在攻丝头中设置摩擦片传动，利用摩擦片传动的特性就可以很好地解决这个问题，现在龙门式攻丝机已基本设计出来，其性能正在等待生产实践的验证。

It is consisted of master pincer and back pincer,its nose opening is big.It is powered by a hydraulic motor with low speed and high torque,and driven by spur gear,4-fift gearing ,overhand mounting and pneumatic advancing and returningl.

由主钳和背钳组成，钳头开口大，低速大扭矩油马达输入动力、直齿圆柱齿轮传动，四档变速，悬吊安装，气动进退。

Idlers use stamped bearing house. Using wide clearance bearing and multi-layer labyrinth seal improves service life, reduces rotation resistance and friction coefficient. Cast welding and keyless connection has been used for pulley, Hydraulic coupling and hard surface cone cylinder gear speed reducer for drive unit, angle type structure for head frame, so these improve starting performance, drive efficiency, load capacity and service life, reduce floor area and weight of equipment.

托辊采用了35°槽型前倾结构，辊子为冲压轴承座结构，大游隙轴承和册层迷宫密封，提高了寿命，降低了旋转阻力和摩擦系数，滚筒采用了铸焊结构和无健联接，驱动单元采用了液力耦合器和硬齿面圆锥圆柱齿轮减速机，头架采用角型结构，从而改善了启动性能，传动效率，承载能力和使用寿命，减少了占地面积和设备重量。

The company's main products are oil pipe, tubing joints, universal joints, ball head, gear, and wheel bolts high strength fasteners, all kinds of Auto accessories, all kinds of stamping parts series.

本公司现的主要产品有油管、油管接头、万向节、球头、齿轮、以及车轮螺栓等高强度紧固件、各种汽摩配件系列、各种冲压件系列。
