Product Description Helical gear is a cylindrical gear with helical teeth. Helical gears have advantages such as smooth transmission, good meshing performance, high overlap, high gear strength, quietness, and low vibration compared with spur gears. And it can transmit high power.Helical gears are different from spur gears because their tooth profile is helical and generates axial thrust. Thrust can be eliminated through thrust bearings or a combination of left and right helical gears to form a helical gear. A pair of meshing helical gears must have the same helix angle and opposite helix directions. Gear transmission has the advantages of reliable operation, constant transmission ratio, high efficiency, the ability to transmit motion between any two axes in space, and wide adaptability.Key FeaturesTooth Geometry:Teeth are cut at a helix angle (typically 15°-45°), forming a helical pattern around the gear circumference. This angle enables gradual tooth engagement, reducing noise and vibration.Contact Mechanism:Teeth engage with line contact (vs. point contact in spur gears), distributing loads more evenly across the tooth face.-Axial Thrust: Helical teeth generate axial forces during operation, requiring thrust bearings or paired helical gears ("herringbone gears") to counteract this force.Rotation:Can transmit motion between parallel shafts (same direction) or crossed shafts (non-parallel, non-intersecting axes).Axial Thrust:Helical teeth generate axial forces during operation, requiring thrust bearings or paired helical gears ("herringbone gears") to counteract this force.Materials:C45 steel ,42CrMo, 20CrMnTi ,Alloy steel, SUS303/304/316, 40Cr, cost steel, Alloy Steel,Brass, Bronze, Iron, Aluminum AlloySmooth Operation:Gradual tooth engagement minimizes shock loads and noise, ideal for high-speed applications (e.g., automotive transmissions).Higher Load Capacity: Extended contact lines distribute stress evenly, supporting greater torque transmission.Versatility:Suitable for both parallel and crossed shaft configurations.Compact Design:Achieves higher power density compared to spur gears in the same space.Product ParametersType:Spur Gear, Helical Gear, Bevel Gear, Gear shaft, Custom gears, Rack, Helical Rack, Precision gear.Module (m):Determines tooth size, calculated as m = d/z*cosβ where d is pitch diameter and z is the number of teeth and beta is the helical angle.Pressure Angle (α): Typically 20° in the normal plane (standard), affecting tooth strength and contact ratio.Helix Angle (β):Defines the inclination of teeth relative to the gear axis. Larger angles improve smoothness but increase axial thrust.Face Width:Wider face widths compensate for axial thrust and enhance load capacity.Heat Treatment:High-frequency quenching, Quenching and tempering, carbonitriding, carburizing and quenchin; 50- 62HRCApplications:Automation Equipment, Machinery Equipment, Medical Equipment, Robot, semiconductor Equipment, Automotive.Product Pictures Company ProfileYongfeng Gear is a professional manufacturer specializing in the research and development and manufacture of precision transmission components.
