Abstract
A kind of even gap completely fills cylinder needle bearing, comprise outer ring and cylinder needle roller, outer ring is the structure that cylinder two ends are provided with interior flanging, on the raceway that the inner headed face that some cylinder needle rollers are arranged in outer ring is formed, cylinder needle roller is provided with undergauge support end at the two ends of cylinder, separately there is the sheet ring retainer in required tool withdrawal groove when being arranged on outer ring raceway two ends processing raceway, uniform some needle roller support holes on retainer end face, each needle roller support hole has towards the opening in direction, the retainer center of circle, the support end at cylinder needle roller two ends enters needle roller support hole and supporting and location by the opening in needle roller support hole.The utility model can realize small―gap suture and completely fill cylinder needle roller and nothing friction between cylinder needle roller, possesses the ability of ability and the large carrying being suitable for High Rotation Speed, adapt to the actual state of alternately operating between engineering machinery underload, heavy load, impulsive load, high speed and low speed length, the life-span of bearing is increased greatly, decrease damage and the maintenance expenses of equipment, improve life-span and the utilization efficiency of equipment.
Description
Technical field
The utility model relates to a kind of even gap and completely fills cylinder needle bearing, is applicable to winch, micro-gearbox, oil hydraulic pump class engineering machinery.
Background technique
Along with the extensive use of current engineering machinery series products in production and construction, the constant interval of work loads is increasing, machinery equipment is in high-speed and continuous running or varying load in short-term under percussion, it is more and more severe that the working condition of bearing becomes, simultaneously a large amount of heat can not be dispersed into surrounding environment after producing completely, rapidly, and operating temperature is uprised simultaneously; Under large load, varying load percussion and high temperature operating conditions, the life-span of bearing reduces greatly, the speed goes damaged is fast, add engineering time and the expense of equipment, shorten the working life of equipment, how by improving bearing capacity, to solve the requirement of upper genus contradiction more and more stronger.
Summary of the invention
The purpose of this utility model is to provide a kind of even gap and completely fills cylinder needle bearing, with less individuality under the working environment that temperature is higher, the equipment operation under light, middle load effect can be adapted to, the equipment operation under the heavy load of short time or varying load effect can be met again, the large bearing capacity that full pin packaging shaft namely will be had to hold, avoids or reduces full pin packaging shaft holding the frictional heat produced in the process of running up again.
The purpose of this utility model realizes as follows: this bearing comprises outer ring and cylinder needle roller, outer ring is the structure that cylinder two ends are provided with interior flanging, on the raceway that the inner headed face that some cylinder needle rollers are arranged in outer ring is formed, cylinder needle roller is provided with undergauge support end at the two ends of cylinder, separately there is the sheet ring retainer in required tool withdrawal groove when being arranged on outer ring raceway two ends processing raceway, uniform some needle roller support holes on retainer end face, each needle roller support hole has towards the opening in direction, the retainer center of circle, the support end at cylinder needle roller two ends enters needle roller support hole and supporting and location by the opening in needle roller support hole.Cylinder needle roller is supported by the retainer at two ends, remove the window beam of retainer between cylinder needle roller, solid matter is convenient to cylinder needle roller slot milling, being planted by retainer in technology groove residual in the course of working of outer ring guides needle roller to move, and make to be in the needle roller end of not playing actual bearer effect in the technology groove of outer ring and reduced by reducing, can distance evenly implant in retainer at regular intervals, by controlling the spacing in retainer needle roller support hole, gap between cylinder needle roller be may diminish between 0.1mm ~ 0.4mm but be not in contact with each other mutually, bearing capacity and the effect of full dress pin is fully meet under the condition not reducing cylinder needle roller payload length.When long-time large load or varying load percussion, all cylinder needle rollers are all in rolling condition and mutually without friction contact, when not changing bearing profile installation dimension, by optimizing bearing interior space and design, achieve and contactlessly between cylinder needle roller in bearing operation process completely fill needle construction, improve the bearing capacity of bearing most possibly from structure in limited space, break full pin packaging shaft and held because of unordered between needle roller that friction generates heat is violent and be unsuitable for the forbidden zone of High Rotation Speed, and inherit its high bearing capacity, substantially increase the working life of bearing.During assembling, resilient plastic holder is first loaded in bearing outer ring, then cylinder needle roller undergauge support end is inserted needle roller support hole by retainer interference opening, all cylinder needle rollers are freely rotated without coming off.
Retainer can be directly sheet circle structure, also bulge loop can be connected with at the internal circle of sheet circle structure, the inner circle Spielpassung that in the outside diameter of bulge loop and outer ring, flanging is formed, the interior circular diameter of bulge loop is less than the diameter of a circle that in all cylinder needle rollers, side bus surrounds, the diameter of the diameter of a circle that in all cylinder needle rollers, side bus surrounds i.e. bearing installation shaft upper bearing (metal) mounting point, the effect of bulge loop, one is the intensity that can increase retainer, and two is improve anti-dust performance.
The utility model can realize small―gap suture and completely fill cylinder needle roller and nothing friction between cylinder needle roller, possesses the ability of ability and the large carrying being suitable for High Rotation Speed, adapt to the actual state of alternately operating between engineering machinery underload, heavy load, impulsive load, high speed and low speed length, the life-span of bearing is increased greatly, decrease damage and the maintenance expenses of equipment, improve life-span and the utilization efficiency of equipment.

Fig. 3 is the structural representation of retainer in the utility model.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the utility model comprises outer ring 1 and cylinder needle roller 2, outer ring 1 is the structure that cylinder two ends are provided with interior flanging, on the raceway that the inner headed face that some cylinder needle rollers 2 are arranged in outer ring 1 is formed, cylinder needle roller 2 is provided with undergauge support end at the two ends of cylinder, separately there is the sheet ring retainer 3 in required tool withdrawal groove when being arranged on raceway two ends, outer ring 1 processing raceway, retainer 3 is connected with bulge loop at the internal circle of sheet annulus, the inner circle Spielpassung that in the outside diameter of bulge loop and outer ring 1, flanging is formed, the interior circular diameter of bulge loop is less than the diameter of a circle that in all cylinder needle rollers 2, side bus surrounds, uniform some needle roller support holes on retainer 3 end face, each needle roller support hole has towards the opening in direction, retainer 3 center of circle, the support end at cylinder needle roller 2 two ends enters needle roller support hole and supporting and location by the opening in needle roller support hole.Be in the window beam between needle roller by removal bearing tradition cylindrical retainer, increase the state that needle roller quantity reaches full dress pin, structure, improve bearing capacity most possibly.
