1. Basic requirements: It is necessary to make the journal and the sliding bearing evenly and finely touched; and there must be a certain cooperation gap. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2, touch point: the actual touch condition of the journal and sliding bearing surface; can be marked by the number of practical touch points per unit area. The more touch points, the finer and more uniform; the better the scratch bearing is indicated; otherwise; It is indicated that the sliding bearing is not good enough. Generally speaking, the more fine the touch point is, the more difficult it is to scrape. The touch point should be determined according to the function and working condition of the sliding bearing.
3. Touch angle: refers to the central angle of the contact surface of the journal and the sliding bearing. The touch angle is not too large or too small. The touch angle is too small, so that the sliding bearing pressure is added; when it is severe, the sliding bearing will be more severe. Large deformation; accelerated wear; shortened service life, too large touch angle; will affect the composition of the oil film; can not obtain outstanding liquid smoothness. Experimental research indicates; the limit of the sliding bearing touch angle is 120 °. When the sliding bearing wears to this When a touch angle is used, the liquid is smooth and damaged. Therefore, the condition of the sliding bearing is not affected. The smaller the touch angle is, the better. The theoretical analysis from the conflicting force distance; when the touch angle is 60°; the conflicting moment is the most.虼 ㄒ椋 ㄒ椋 俑哂 俑哂 俑哂 500r / min sliding bearings; touch angle selection of 60 °; rotating bearings below 500r / min; touch angle can be selected 90 °; can also choose 60 °.
