Gear shaping is also a widely used tooth profile machining method, which is often carried out together with gear hobbing. It is equivalent to meshing a pair of cylindrical gears, and the gear shaper cutter is equivalent to a modified gear. During gear shaping, the gear shaping cutter moves up and down, and the cutting is down; When the gear shaper cutter moves upward, the workpiece or cutter retreats a distance in the radial direction to prevent the cutter from scratching the machined surface; There are generating motion and radial feed motion.
Slewing Bearing
1. Introduction of Xuzhou Helin slewing ring bearings
Xuzhou Helin is a professional manufacturer in slewing ring bearings. We can also design and make other standard and non-standard ball slewing ring bearings, roller slewing bearings and precision slewing ring bearings as per customer's different technical requirements.Slewing ring bearing is also called slewing ring, slewing bearing, turntable bearing, and rotary bearing. Slewing ring bearing is a bearing that able to bear axial load, radial load and overturning torque. Under normal circumstances, slewing ring bearings have their own mounting holes, lubricant holes and seal holes, to meet the different needs of the various host working under the various conditions; On the other hand, slewing ring bearing itself has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.
