Grease lubricated star wheel speed reducer for bearing
TLDR
The star wheel speed reducer as discussed by the authors consists of a base and an involute transmission part with small teeth difference in the base, where gears are lubricated with gear oil and rolling bearings with bearing grease, and a sealing part is arranged on the two sides of the first and second bearings respectively.Abstract:
The invention relates to the technical field of involute speed reducers with small teeth difference and in particular relates to a grease lubricated star wheel speed reducer for a bearing. In a base, gears are lubricated with gear oil and rolling bearings are lubricated with bearing grease. The star wheel speed reducer comprises a base and an involute transmission part with small teeth difference in the base. The star wheel speed reducer is characterized in that an input shaft is supported in an inner hole of a fixing bracket by two first sealed bearings; each planet gear is supported on double eccentric bushings by two second sealed bearings; the two ends of double eccentric shafts are respectively supported in inner holes on the two side walls of the fixing bracket by third sealed bearings; eccentric sections on the double eccentric shafts are supported in pin holes of the planet gears by two fourth sealed bearings; an output shaft is supported in an inner hole of the base by first and second bearings with space rings; and a sealing part is arranged on the two sides of the first and second bearings respectively. The star wheel speed reducer has the beneficial effects that the bearing runs reliably, so the speed reducer has long service life and low noise.read more
