Abstract
The utility model discloses a low-noise bearing. The low-noise bearing comprises an outer ring, an inner ring and a cylindrical roller, wherein the outer ring and the inner ring form a roller path; the cylindrical roller is installed inside the roller path; positioning grooves are formed at two ends of the roller path; positioning rings are arranged at two ends of the cylindrical roller; the positioning rings roll inside the positioning grooves; retaining racks are installed between the outer ring and the inner ring at intervals; the surface of the cylindrical roller is coated with a molybdenum disulfide coating; an inner wall of the outer ring and an outer wall of the inner ring are also coated with the molybdenum disulfide coating; and the molybdenum disulfide coating has a lubricating effect. The low-noise bearing realizes positioning in the running process through the positioning grooves on the roller path and the positioning rings on the cylindrical roller, so that the relative displacement is reduced and the noise of a bearing is further reduced; and the surfaces of the roller and the roller path are coated with the molybdenum disulfide coating, so as to realize the lubricating effect, and the noise can be further reduced.
Description
Technical field
The utility model relates to field of bearings, relates in particular to a kind of low noise bearing.
Background technique
Bearing is in mechanical transmission course, to work the parts of fixing and reducing the load friction factor.Also we can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the contemporary machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process.Press the difference of motor element frictional property, bearing can be divided into two types on rolling bearing and sliding bearing.
Mostly present widely used bearing is rolling bearing, comprises ball bearing and roller bearing.Rolling bearing is exactly that the axle of running and the sliding friction between the axle bed are become rolling friction, thus the mechanical component of a kind of precision of the loss of reducing friction.
Along with material and improvement of Manufacturing Technology, the plurality of applications occasion, like precision instrument, car and household electric appliance, strict day by day to the requirement of bear vibration and noise characteristic, noise control has risen to the first important quality index in many fields.Bearing because of vibration and noise inefficacy usually prior to fatigue failure; And vibration and noise are the concentrated expression of bearing performance; Theoretical research and engineering practice have shown that all every factor that influences fatigue life affects bearing vibration and noise characteristic bar none, and good to a certain extent vibration and noiseproof feature are indicating long working life.Can predict, industry to bearing vibration and noiseproof feature focus on quite over a long time in can not weaken, and will strengthen day by day.
The main source of the noise in the bearing operation process is the deviation slightly between roller and the raceway; In continual operation process; Trickle inclination or displacement can appear between roller and the raceway unavoidably; Though this trickle inclination or displacement can not impact the performance of bearing, can make a noise.
The model utility content
The utility model is intended to propose a kind of low noise bearing that reduces the bearing noise through the displacement in the minimizing running.
Embodiment according to the utility model proposes a kind of low noise bearing, comprises outer ring, inner ring and cylindrical roller; Outer ring and inner ring form raceway, and cylindrical roller is installed in the raceway, and the two ends of raceway offer locating slot; The two ends of cylindrical roller have positioning ring, and positioning ring rolls in locating slot.
In one embodiment, retainer also is installed at interval between outer ring and the inner ring.
In one embodiment, the surfaces coated of cylindrical roller is covered with the molybdenum disulfide coating.Be coated with the molybdenum disulfide coating on the inwall of outer ring and the outer wall of inner ring.The molybdenum disulfide coating realizes lubrication.
The low noise bearing of the utility model utilizes locating slot and the positioning ring on the cylindrical roller on the raceway to realize the location in the operation process, reduces relative displacement to reduce the bearing noise.Roller and raceway face are coated with the molybdenum disulfide coating, realize lubrication, can further reduce noise.
Description of drawings
Fig. 1 has disclosed the structural drawing according to an embodiment's of the utility model low noise bearing.
Embodiment
With reference to shown in Figure 1, the utility model has disclosed a kind of low noise bearing 100, and this low noise bearing 100 comprises outer ring 102, inner ring 104 and cylindrical roller 106.Outer ring 102 forms raceway with inner ring 104, and cylindrical roller 106 is installed in the raceway.The two ends of raceway offer locating slot 103, and locating slot 103 is made up of with second groove that is opened in the corresponding position on the inner ring first groove that is opened in respectively on the outer ring.The two ends of cylindrical roller 106 have positioning ring 105, and positioning ring 105 is from the surperficial upper process of cylindrical roller 106, and positioning ring 105 rolls in locating slot 103.The cooperation of positioning ring 105 and locating slot 103 can axially make cylindrical roller 106 and raceway relative fixed, avoids because the noise that produces after the axial relative displacement.Also at interval retainer is installed between outer ring 102 and the inner ring 104, retainer does not illustrate in the drawings, but the retainer of installation interval setting habitually practise, do not do here and give unnecessary details.In one embodiment, in order further to promote noise reduction, the surfaces coated of cylindrical roller 106 is covered with the molybdenum disulfide coating, simultaneously, also is coated with the molybdenum disulfide coating on the inwall of outer ring and the outer wall of inner ring.Molybdenum disulfide is a kind of effective solid lubricant, can play lubrication effect preferably, helps further reducing noise.
The low noise bearing of the utility model utilizes locating slot and the positioning ring on the cylindrical roller on the raceway to realize the location in the operation process, reduces relative displacement to reduce the bearing noise.Roller and raceway face are coated with the molybdenum disulfide coating, realize lubrication, can further reduce noise.
