introduction:Short-term oil changes are very rare, For the staff。And often add more grease。If the staff is required to change the lubricant every two to three weeks,Add one ounce of grease at a time。These suggestions lead him from the beginning to build on some unknown factors that have no practical significance All need to be replaced with grease nowFAGAligning ball bearings[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,To reduce motion

introduction:The planetary reducer is suitable for applications requiring a high torque-to-volume ratio(The value is in2to100between,Depends on the ratio size)、High-precision motion control applications with high torsional stiffness and low back backlash,It depends on the application。The planetary reducer increases torque by the same multiple as the reduction ratio,It also reduces the rotational speed by the same factor,Keep the corresponding motor running at high speed。For enhanced stability,It also reduces the load equivalent inertia on the motor。In short,The use of planetary reducers allows machine manufacturers to build smaller、More economical motion control equipment。 The planetary reducer can be mounted directly to the AC and DC servomotors

introduction: Heat treatment of molds in the manufacturing process is a process used by most molds for a long time,Since the last century70The beginning of the decade,The idea of pre-hardening has been put forward internationally,However, due to the rigidity of the machining machine tool and the restriction of cutting tools,The hardness of the pre-hardening can not reach the hardness of the mold,Therefore, the research and development investment of pre-hardening technology is not large。With the improvement of the performance of machine tools and cutting tools,The development of pre-hardening technology of die materials is accelerated,To the last century80age,The proportion of pre-hardened modules used in plastic molding materials in developed countries has reached30(At present in60above)。Our country is in the last world
