Description
Technical field
The utility model relates to technical field of bearings, is specially a kind of radial bearing.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.By the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two class.
Traditional bearing is in running, and the temperature of Bearing inner is often higher, causes the performance parameter that conveniently can not adjust bearing, causes bearing to debug not convenient.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the radial bearing providing a kind of easy cooling.
For achieving the above object, the utility model provides following technological scheme: a kind of radial bearing, comprise radial bearing shell, the axial two ends of described radial bearing shell are connected to the oily frame of control, the inner annular array of described radial bearing shell has several radial tile fragments, filler opening is left between two radial tile fragments of arbitrary neighborhood, radial tile fragment is tile, comprise the first cambered surface and the second cambered surface, several first cambered surfaces are positioned on same cylindrical side, described radial bearing shell annular array has some groups of nozzle sets, nozzle sets comprises at least one nozzle, described filler opening is aimed at the nozzle of nozzle, the two ends of described radial tile fragment and control each circular array between oily frame and show the positioning pin that several limit radial tile fragment position, the erection of described each control oil has oil leak hole, one end of oil leak hole is provided with throttling plug.
Further, the group number of described nozzle sets is 5 groups, often organizes nozzle sets and comprises 2 nozzles, often organize the centerline parallel of two nozzles of nozzle sets.
Further, the number of described positioning pin is 10.
Further, the inwall of described radial bearing shell is anchor ring, and the radius of curvature of the inwall of radial bearing shell is larger than the radius of curvature of the second cambered surface.
Further, the afterbody of described nozzle is horn-like.
Contrast the deficiencies in the prior art, the beneficial effect that the technological scheme that the utility model provides is brought: 1. the utility model adopts 5 groups of nozzle sets, often organize 2 nozzles, two nozzles spray lubricant oil simultaneously, make rotating shaft axially be subject to oil evenly.Lubricant oil is directly ejected on axle by nozzle, is conducive to the formation of dynamic pressure oil film, effectively can reduce the power consumption of bearing, can regulate oil inlet quantity by the nozzle changing different pore size.2. the utility model is by the design larger than the radius of curvature of the second cambered surface of the radius of curvature of the inwall of radial bearing shell, make tile fragment flexible swinging, simultaneously owing to there is gap between the second cambered surface and the inwall of radial bearing shell, add the capacity of lubricant oil in die cavity, accelerate scattering and disappearing of tile fragment heat, effective reduction watt temperature, and then the performance parameter of convenient adjustment bearing, bearing debugging is convenient.3. oily for control frame is fixed on radial bearing shell by the utility model, is limited the position of radial tile fragment by positioning pin, is conducive to the flexible swing of radial tile fragment, makes radial tile fragment be not easy to damage.4. the utility model increases throttling plug by the oil leak hole of the oily frame of control, regulates the dredge oil amount of bearing, controls the temperature of tile fragment.
