1. characteristics of helical gear:
(1) The meshing is better. Compared with the spur gear, the helical gear meshes more fully during the transmission process, the gear transmission is more stable, and the transmission for force is more linear;
(2) Long service life. The helical gear transmission has a large coincidence degree, a long meshing time and a large contact area, which makes the stress smaller, thereby improving the bearing capacity of the gear and prolonging the service life of the gear;
(3) The structure is relatively compact. The structure of the helical gear is relatively compact, and a smaller gear mouse can basically bring about a relatively ideal deceleration effect.
2. Helical gear material and process:
High-strength mold steel is selected as the material of the helical gear, and nano-coating is used as the surface treatment process. The overall Rockwell hardness HRC value of the gear reaches 62-65; the surface hardness HV value reaches 2000-2500, which greatly ensures the strength of the gear. , wear resistance.
3. Uses:
(1) The plastic spur gear kit can be replaced for gear upgrade.
(2) For other extruders that use double gear pairs, such as mini V1 or V2 extruders, for sherpa metal extruders, for sherpa extruders, etc.
(3) Other double gear extruders or drivers of the same size.
