Description
Technical field
The utility model relates to a kind of bearing, particularly relates to a kind of high-mechanic noise free gear-bearing.
Background technique
Bearing is the comparatively conventional fixed member in engineering machinery.Along with socioeconomic fast development, the demand of market to bearing is increasing, requires also more and more higher.Existing bearing axis hole and shaft design are overall structure or offer oil groove at axis hole root or local, such design exist axle and axis hole area of contact large and be directed at noise greatly with lubricate not good shortcoming.At the root notching construction of axis hole, the lubricant oil added in axis hole after motor rotation, easily flow to the bottom of motor, not good to the fitting surface lubrication effect of axle and axis hole, the shortcoming that easy generation current is large and noise is large.Along with today more and more higher to the requirement of quality of product and Product Precision in recent years, the noise of bearing is large and lubrication effect is not good will directly cause the downslide of the total quality of product, the reduction competitiveness of product in market.How gear transmission and loading ability of bearing are effectively combined in addition and solve that the number of components in prior art is many, quality weight, the problem of the poor reliability of transmission of power is the current technical issues that need to address of those skilled in the art simultaneously.
Model utility content
The purpose of this utility model is the high-mechanic noise free gear-bearing providing a kind of bearing capacity high for above-mentioned shortcomings and deficiencies of the prior art, this bearing effectively can not only solve the lubrication problem of motor shaft and axis hole, effectively can reduce the wearing and tearing of axle and axis hole and effectively reduce running noise of motor and electric current, and effectively can solve that the number of components in prior art is many, quality weight, the problem of the poor reliability of transmission of power simultaneously.
The purpose of this utility model is realized by following technological scheme.
A kind of high-mechanic noise free gear-bearing, comprises outer ring, inner ring, rolling element; Rolling element is between inner ring and the raceway of outer ring; It is characterized in that: in described inner ring, have axis hole, have in the inwall surrounding of this axis hole some towards the open-topped oil groove of axis hole uniformly; Raceway between described outer ring and inner ring is two roller path structure and 30-50mm of being separated by between two raceways; The outer side surface of described outer ring is also provided with gear part.
Wherein, described gear part is be evenly distributed on the gear rack on the outer side surface of described outer ring.
Wherein, be also provided with two annular oil seal between described outer ring and inner ring, these two annular oil seal lay respectively at described multiple rolling element both sides.
Wherein, described inner ring, outer ring are made by modified structural steel.
Compared with prior art, the advantage of high-mechanic noise free gear-bearing described in the utility model is:
1, the raceway between outer ring of the present utility model and inner ring is two roller path structures, significantly promoting the load-carrying properties of bearing, more meeting the usage requirement of wind electricity pitch variable bearings when not strengthening bearing boundary dimension.
2, bearing and gear are carried out Integration Design by the utility model, and namely the outer shroud of gear and bearing is designed to integrative-structure, effectively reduces number of spare parts, alleviates quality, can improve the stability of transmission of power simultaneously.
3, the utility model has some towards the open-topped oil groove of axis hole uniformly in the inwall surrounding of axis hole, after axle is arranged on axis hole, lubricant oil is injected in some oil grooves of the inwall surrounding of this axis hole, owing to having the rubbing surface that oil groove directly can reduce axle and shaft hole inner wall uniformly at shaft hole inner wall, reduce the friction factor of axle and axis hole, reduce noise and electric current.Again because its oil groove is the uniform inwall surrounding being opened in axis hole towards axis hole open top, the lubricant oil added in oil groove after motor rotation, not easily flow to the bottom of motor, the fitting surface lubrication effect of axle and axis hole is promoted greatly.
Accompanying drawing explanation
Fig. 1 is that sectional structure schematic diagram is looked on the right side of the utility model high-mechanic noise free gear-bearing.
Fig. 2 is the main TV structure schematic diagram of the utility model high-mechanic noise free gear-bearing.
In figure: 1 inner ring, 2 rolling elements, 3 outer rings, 4 oil grooves, 5 axis holes, 6 annular oil seal, 7 gear part.
Embodiment
Structure of the present utility model is further described below in conjunction with Fig. 1, Fig. 2.
A kind of high-mechanic noise free gear-bearing comprises outer ring 3, inner ring 1, rolling element 2; Rolling element 2 is between inner ring 1 and the raceway of outer ring 3; Raceway between described outer ring 3 and inner ring 1 is two roller path structure and 30-50mm of being separated by between two raceways.Raceway between outer ring 3 of the present utility model and inner ring 1 is two roller path structures, significantly promoting the load-carrying properties of bearing, more meeting the usage requirement of wind electricity pitch variable bearings when not strengthening bearing boundary dimension.
The outer side surface of described outer ring 3 is also provided with gear part 7, and described gear part 7 is for being evenly distributed on the gear rack on the outer side surface of described outer ring 3.Bearing and gear are carried out Integration Design by the utility model, and namely the outer shroud of gear and bearing is designed to integrative-structure, effectively reduces number of spare parts, alleviates quality, can improve the stability of transmission of power simultaneously.
Have axis hole 5 in described inner ring 1, have in the inwall surrounding of this axis hole 5 some towards the open-topped oil groove 4 of axis hole 5 uniformly.After axle is arranged on axis hole 5, lubricant oil is injected in some oil grooves 4 of the inwall surrounding of this axis hole 5, owing to having at axis hole 5 inwall the rubbing surface that oil groove 4 directly can reduce axle and axis hole 5 inwall uniformly, reduce the friction factor of axle and axis hole 5, reduce noise and electric current.Again because its oil groove 4 is uniform inwall surroundings being opened in axis hole 5 towards axis hole 5 open top, the lubricant oil added in oil groove 4 after motor rotation, not easily flow to the bottom of motor, the fitting surface lubrication effect of axle and axis hole 5 is promoted greatly.
Between described outer ring 3 and inner ring 1, be also provided with two annular oil seal 6, these two annular oil seal 6 lay respectively at described multiple rolling element 2 both sides.The utility model arranges annular oil seal 6, and energy effective sealing bearing, prevent dust from entering in raceway, bearing operation noise is low, rubs little, effectively can improve the bearing failure because high-speed resistance causes, substantially increase the working life of bearing.
More than show and describe basic principle of the present utility model and major character and advantage thereof.The technology personage of the industry should understand; the utility model is not by the restriction of above-mentioned implementing regulations; describe in above-mentioned implementing regulations and specification just for illustration of principle of the present utility model; under the prerequisite not departing from the utility model principle and scope; the utility model also can have various changes and modifications, and these changes and improvements all belong within the scope of claimed the utility model.
