Abstract
The utility model discloses an isolation block of a slewing bearing, which has a cylindrical block with two end surfaces as ball sockets, a through hole is formed on the cylindrical block in the axialdirection, oil grooves are formed in the ball sockets, and one or more than two concave holes facing inwards are formed on the outer surface of the cylindrical block. On the section in the radial direction of the cylindrical block, the concave holes are formed in the shape of a 'V', that is, the concave holes possess a reducing structure from the surface of the block to the interior part; the number of the concave holes on the outer surface of the cylindrical block is 4 to 8 most preferably; and the material of the cylindrical block adopts high-density polyethylene. With the adoption of the structure, the concave holes facing inwards are formed on the outer surface of the cylindrical block, so that the raw materials for manufacturing isolation blocks are saved, the mechanical strength ofthe isolation block is improved, and the precision of manufacturing isolation blocks is further ensured.
Description
Technical field
The utility model relates to a kind of pivoting support bearing, and the spacing block of a kind of pivoting support bearing of more specifically saying so belongs to machinery manufacturing technology field.
Background technique
Wind-power electricity generation is as an emerging rising industry, integrates green, energy-saving and environmental protection, distinguishing feature such as renewable.Along with the global energy resource problem is outstanding day by day, particularly global warming becomes clear day by day, and wind-powered electricity generation becomes the important component part of world energy sources.In recent years, China classifies wind power plant as the state key research project, and domestic enterprise improves constantly the research and development ability of Large-scale Wind Turbines by technology transfer and independent research, in this field rapid progress has been arranged.
Pivoting support bearing is mainly used in wind-driven generator, is the core component of wind power equipment, its requirement be the life-span long, reliability is high, good stability, starting torque is little, rotation is flexible.Its structure comprises inner ring, outer ring and steel ball, the excircle of inner ring to the inner circumference of outer ring to arc groove is all arranged, this two arc groove is corresponding, steel ball places in two curve baths, and is between the two ends of inner ring and outer ring that the sealing shape is movable to be cooperated.
Pivoting support bearing is in operation process, and commutation and impulsive load are to having a significant impact the fatigue life of steel ball.Fray for fear of steel ball, guarantee the starting torque and the running accuracy of bearing, improve the life-span of bearing, between adjacent steel ball, adopt spacing block, existing spacing block structure is axially to have logical empty cylindrical body, has dug ball-and-socket at two end faces, is provided with oil groove in ball-and-socket.Be between the ball-and-socket of spacing block and steel ball and be slidingly matched.The spacing block of said structure exists weight big, the deficiency that cost of material is high, and simultaneously, the mechanical strength of spacing block and precision also await further raising.
The model utility content
A kind ofly exist in light weightly at the invention provides, the spacing block of the pivoting support bearing that the cost of material is low improves simultaneously further the mechanical strength and the precision of spacing block.
For achieving the above object, the utility model has adopted following technological scheme: a kind of spacing block of pivoting support bearing, the cylindrical structure block that it has two end faces is ball-and-socket, described cylindrical structure block axially have a through hole, the described oil groove that is provided with in ball-and-socket, the outer surface of its described cylindrical structure block is provided with shrinkage pool inside more than or two.
Along in the radial section of cylindrical structure block, described shrinkage pool is " V " font, and promptly shrinkage pool inwardly has the structure of contraction from block surface.Preferably 4-8 of the shrinkage pool quantity of the outer surface of described cylindrical structure block.The material of described cylindrical structure block is a high density polyethylene (HDPE).
Adopt said structure, on the outer surface of cylindrical structure block, be provided with inside shrinkage pool, the raw material of making spacing block have been saved on the one hand, experimental results show that, compared with prior art, the utility model can reduce weight 20%-35% for the spacing block of same specification, just can save the cost of raw material of 20%-35%; On the other hand, the stressed distribution that effective change spacing block is set of shrinkage pool makes the block of spacing block be similar to the distributed architecture of stiffening rib, improves the mechanical strength of spacing block; Again on the one hand, the thermoplastic mode is adopted in the spacing block manufacturing of high-density polyethylene material, can produce shrinkage phenomenon in manufacture process, because the setting of shrinkage pool has reduced its contour projector, also just the precision of spacing block manufacturing has been obtained further assurance.
Description of drawings
Fig. 1 is the structural representation of the spacing block of the utility model pivoting support bearing;
Fig. 2 is a spacing block sectional drawing radially.
Among the figure: 1-ball-and-socket, 2-through hole, 3-oil groove, 4-shrinkage pool.
Embodiment
As shown in Figure 1, the spacing block of pivoting support bearing of the present utility model, the cylindrical structure block that it has two end faces is ball-and-socket 1, described cylindrical structure block axially have a through hole 2, describedly in ball-and-socket 1, be provided with oil groove 3, the setting of oil groove 3, can store lubricant oil, make bearing that self-lubricating property be arranged, improved the moving condition of rolling element, and guaranteed the rotating synchronism between rolling element and the spacing block.Said structure and prior art are similar, therefore, no longer are described in detail.
As the maximum characteristics of the spacing block of pivoting support bearing of the present utility model be: the outer surface of described cylindrical structure block is provided with shrinkage pool inside more than or two 4.The quantity of described shrinkage pool 4 is 4-8 preferably, and the quantity of the shrinkage pool 4 of present embodiment is 6, can be other quantity according to actual conditions certainly, as 4,8 etc.The material of described cylindrical structure block is can high density polyethylene (HDPE), make spacing block have easy to process, friction factor is little, wearing and tearing are low, and is and shock-resistant, chemical stability height, cheap characteristics.
The concrete shape of described shrinkage pool 4 divides the radial section of cylindrical structure block, circular shaft to describe to section two aspects.
Referring to Fig. 2, along in the radial section of cylindrical structure block, because block two sides are the arc surface of ball-and-socket 1, therefore, described shrinkage pool 4 is " V " font, and promptly shrinkage pool 4 inwardly has the structure of contraction from block surface.Certainly the sidewall of shrinkage pool 4 can be the arc with the arc surface coupling of ball-and-socket 1.
Along in the axial section of cylindrical structure block, described shrinkage pool 4 can " V " font or " U " font.
