In the face of strong domination of foreign products, China's reducer industry is facing a serious market crisis, the crisis greatly stimulate the domestic reducer enterprises in the technology, management has increased investment, and strive to form a counter to foreign products. Want to open up a broader market, we must first ensure their own development. Whether it is technology or management should form a certain advantage, while stepping up the pace of independent research and development.
Worm gear screw lift through reasonable bite parts, expand the actual contact area and manufacturing artificial oil culvert and other methods, can effectively reduce the contact stress and friction number to improve the carrying capacity of the turbine drive and transmission efficiency.
To improve the bearing capacity of worm gear lift are:
Adjust the position of the turbine, using the contact on the side, and make full use of the occlusal side line contact and sliding speed angle characteristics. Generally, the contact area of the bite-out side accounts for 30% to 40% of the total tooth surface.
Eliminate unfavorable bite parts. Ordinary screw lift turbine box, in the middle of the teeth around the tooth root is not the use of dynamic pressure oil grinding area, often in this area will occur early damage. By adjusting the number of teeth and spacing of the turbine, the degree of bite, so as to improve the carrying capacity of the reducer and expand the scope of use.
If the request is not high can choose cheap materials.
Screw material to choose good wear resistance materials, such as bearing steel, need to be quenched and tempered processing, nut material can only choose a bearing steel, but need to do heat treatment.
The use of turbo screw lifts has greatly improved the effect of the whole machine, the friction is always moving forward, the turbine screw lift and ordinary screw machine is not the same, very fast.
Worm gear screw lift as a hardened file to keep the record turbine, worm gears destroyed, because the worm grinding, surface roughness has improved, but in the course of the use of improper operation or other places, the use of worm surface roughness has increased The
