The quality of the non-standard bearing shaft driving gear hob

Non-standard bearing the quality of the shaft driving gear hob to identify sources: bearing | last updated: - 2020 11 - 10 the quality of the non-standard bearing shaft driving gear hob differential gear hobbing machining accuracy analysis, main shaft gear precision and fitness movement precision, stability, precision and touch is related to the precision. Hob processing work to control the common normal length and gear diameter guarantee fitness movement precision; By manipulation of the tooth shape error, and base pitch error, to guarantee the stability of work precision; With tooth to manipulate any errors to ensure touch precision. Under a roll teeth to show in production and processing of several types of error, the reason to carry out the analysis: gear axial vibration error, gear axial vibration is refers to in a transmission gear turn category; Probe on the tooth groove or transmission gear; Two sides touch with depth; Large variation of the probe relative to the center line of the drive gear. Also drive gear gear relative to dividing line shaft eccentricity; This type of offset is because at the time of equipment parts; Part two the middle hole and right in the middle of table devices do not overlap or error is very big. Or because of top and top hole making poor; Precise locating surface touch owe good produce offset; So the main gear diameter jump from the above reason analysis to solve. In the general level of gear hobbing machine. End milling cutter with general precision; Only the production and processing a magnitude 8 precision gear. The precision of the transmission shaft gear department requirements for level 877; And hob processing mainly two middle hole and inner hole to do precise positioning standards; So the analysis of gear hobbing error origin; Master the methods of guarantee and development of the machining accuracy is critical.

The back axle of the double bearing ring should be fixed on the shaft, in order to avoid relative rotation axis. State of bearing installation method in general, the rotation of the shaft is the most, so the inner hole and shaft of mutual cooperation for a win-win cooperation, the interaction of external cavity and the bearing chamber for the transition. When installing non-standard bearing, should detect axis and shaft axis of flatness. Method is to micrometer and fixed in the inner hole of aluminium plate, rotating bearing ring dovetail guide on watch contact bearings, observe the micrometer pointer. If hand deflection, suggests that collar and axis is not perpendicular. When the shell hole deep, can also be measured with extended microns. After the bearing installed correctly, it can seat completely automatic into the rolling of the roller, to ensure that the rolling body is located in the left and right two roll ring road. If the set, bearing abnormal work not only, and each party will be more serious damage. Because of the collar and the seat ring is not obvious, the difference between should be especially careful when installation, in order to avoid mistakes. In addition, the bearing race center and bearing hole should be set 0. 2 to 0. 5 mm clearance, to compensate for parts processing, security error caused by the deviation, when bearing the toss management center deviation, the gap can ensure the automatic adjustment, prevent contact friction, the normal operation of all.
