Adaptation of the ball bearing hinge maximum design angle corner, the vertical displacement at the position corresponding to the top and, by formula to determine two-way movable hinge bearings, maximum design corner, pots ring diameter, pots ring width, steel soleplate side length, stainless steel plate and the top plate welding connection type if adopted, the ball bearing hinge welding requirements shall calculate the weld length, if only riveted stainless steel screws, the required shear area can calculate the following formula. Bearing shear area shear screws, bearing design capacity, PTFE slide stress, PTFE slide area, PTFE slide design allowable stress, ball bearing hinges standard for 30mpa, PTFE slide diameter, other requirements designed Other requirements cast a movable hinge design bearing, ball bearing hinge allows the sliding surface material combinations for PTFE plate and immortality steel, flat PTFE board should meet the requirements. PTFE slide bearings ball joints plane thickness, flat PTFE slide diameter PTFE slide ball bearing hinge projection height, tolerance is 0.2mm, when the error is 0.3 when measured in the calibration of the measurement point, and in Here anticorrosive coating thickness of less than 30mm, should at least have another measurement points and a reasonable distribution. A guide groove for embedded PTFE sheet, PTFE plate guide groove for a minimum thickness of 5,5mm, the protrusion height of 0.2mm on the PTFE sheet material is used for the ball joint bearing friction coefficient test itself, as well as with inter-layer composite board material fastness and compression test has been done in the material description is not repeated here. When a ball joint bearing surface in combination with a support plane plate bearing, ball bearing slide when the plane part of the support plate to complete the horizontal movement to effect rotation of the plane of the surface portion of the function of a ball joint bearing, if the holder of such made of spherical curved section becomes full-turning type of bearing, spherical bearing in the country called; and as the cylindrical surface becomes a one-way type support. Usually referred to swing column bearing elastic damping movable hinge bearings, ball joints bearing such a smaller radius of curvature of the surface if it is made, you can get a large amount of rotation of the movable hinge supports, such Supports horizontal and rotational movement feature size function depends on the coefficient of friction in contact with the support plate sliding material. So, the ball bearing hinge dust and protective measures must be taken to prevent increased wear and friction coefficient. In addition, if the use of high-strength brass support plate, since the machining accuracy of the contact surface is difficult to control and the year of aging, the friction characteristics are subject to change rotation of the mobile terminal leaving the problem of the presence of impaired function, apart from attention in use, but in is also necessary to limit the amount of rotation of the large.
