Industrial koyo cylindrical roller bearing of the remaining technical analysis

For as long as possible in good condition to maintain the performance of the cylindrical roller bearing was must care and maintenance, in order to prevent accidents from already, to ensure the operation of sex, consumer and economy progress. Enjoy the best conditions of mechanical operation of the corresponding operation specification, stop on a regular basis. Content includes monitor running status, supplement or a change in smooth agent, sealed, check regularly. As maintenance issues in the operation, koyo bearing rotation of the sound, vibration, temperature, state of smooth agent and so on. Bearing cleaning: removing cylindrical roller bearing under repair, the appearance of the first recorded koyo bearing, confirm the residual stock of smooth agent, sampling inspection with the smooth agent, after washing the bearing. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the bearing cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the bearing is not direct contact with dirt from the container. Coarse when cleaning, if make cylindrical roller bearings with dirt, can damage the bearing rolling surface, should be pay attention to. In coarse clean oil, use brush clean up to smooth grease, adhesive, after clean, roughly into fine cleaning). Bearings cracked spalling because of koyo bearings is presented under the action of cyclic load, the contact fatigue damage form appearance is easy to attack, so in order to advance the use of the bearing life, bearing steel must has the very high contact fatigue strength. Hardness is one of the important quality of cylindrical roller bearing quality, the contact fatigue strength, wear resistance, elastic limit has a direct impact. Cylindrical roller bearing steel in the condition of using the hardness of the ordinary to reach HRC61 ~ 65, the ability to make koyo bearings have higher contact fatigue strength and wear resistance. Adhere to the frame is made of nylon 46). To reduce sliding friction between the ball and adhere to the frame. In addition, also lost the direction of rotation of concave and convex shape, which reduces the mixing loss. In addition, after using can slow down the assembly of the shape of the stress, to ensure that the assembly performance. A single insist on torque loss decreased 30 ~ 40%, cylindrical roller bearing torque reduces the 50 ~ 65% overall losses. The speculation that the prius will form 10 and 15 form fuel efficiency from past 35. 5 km/L progress to 38. 0 km/L, the progress of fuel efficiency is about 1 ~ 2% after using this kind of bearing. Koyo bearing parts in the process of consumption, passes through many cold and hot working process, in order to meet the request of mass, high efficiency, high quality, cylindrical roller bearing steel should have good processing performance. For example, the cold and hot forming properties, machinability, hardenability, etc.
