Lapped Spiral Bevel Gear

Spiral Bevel Gear is a type of bevel gear with curved teeth, oblique teeth to provide gradual engagement and larger contact surface at a given time than an equivalent straight bevel gear. Lapping is a process that uses a specially shaped grinding wheel (similar to a fine abrasive wheel) to perform precise, paired, and intermeshing grinding of the gear pair (large and small gears) after heat treatment (quenching). This process does not create new tooth profiles, but rather corrects and optimizes the minute tooth profile distortions (such as twisting, warping, and dimensional changes) caused by heat treatment with extremely high precision and consistency, and significantly reduces surface roughness, the bevel gears under lapping process calls lapped spiral bevel gears.

Features:
​(1)Extremely high geometric accuracy: By correcting heat treatment deformation, we ensure that the tooth profile, tooth direction, and pitch reach micron-level precision, making the meshing theory (conjugate surface) almost perfectly realized.
(2)Very low surface roughness: After lapping, the tooth surface is as smooth as a mirror, greatly reducing friction, wear, and operating heat.
(3)Excellent mesh quality: The position, size, and shape of the contact spots of the gear pair are highly controllable and perfect, ensuring uniform load distribution and an ideal transmission error curve.
(4)Ultimate quietness: It is one of the quietest bevel gears. High precision and low roughness minimize meshing shock and vibration noise, which is crucial for luxury cars and precision machinery.
(5)Extra long life and reliability: Due to its uniform load distribution, low friction loss, and improved residual stress, it has extremely strong resistance to pitting and wear, and its service life far exceeds that of unpolished gears.
(6)Increased carrying capacity: Although the hardness of the tooth surface is determined by heat treatment, the superior tooth surface quality and contact area enable it to transfer the design load more effectively.
