The Worm Reducer-Replacement of Bonvario BL Series Worm Gearbox Size 75 is a high-quality product manufactured using premium materials to ensure maximum reliability and strength, thereby extending the gearbox's service life. The worm is made of steel and undergoes surface hardening treatment, achieving a hardness of 58-60 HRC and molding grinding. In the allowable gear ratio of the module value, the thread grinding adopts the ZI type. This improves the contact between the tooth surfaces, thereby improving the gearbox's performance and reducing its operating noise. The worm wheel uses G20 cast iron wheel hub, with AS 1 bronze wheel rim casting installed on the hub. The gearbox's housing and flange of this series are made of aluminum alloy, with a maximum size of 90. All sizes of this series of gearboxes have universal mounting options. The gearbox under 90 sizes uses ISO VG 320 synthetic oil, requiring almost no maintenance, and does not need to change oil during its service life. Gearboxes of 63 and above specifications are installed with two tapered roller bearings on the worm shaft to increase the mechanical resistance to the axial thrust generated by the worm wheel.



The worm reducer works by transmitting motion and power between two perpendicular shafts by means of a worm gear. The worm is rotated by a motor, and the worm wheel meshes with the worm. As the worm rotates, it turns the worm wheel, transmitting motion and power to the output shaft.
