Abstract
The utility model discloses a slewing bearing used for wind power generation and provided with a precision oil groove. The slewing bearing comprises an oil groove, wherein the connecting positions of the oil groove and a ball track of the slewing bearing are rounded off; and the connecting positions of the side surfaces and the bottom surface of the oil groove are rounded off. The oil groove has a width of 11.5mm and a depth of 21.5mm. The rounding-off of the ball track and the oil groove and the rounding-off of the connecting positions of the side surfaces and the bottom surface of the oil groove ensure that the machining difficulty of the slewing bearing is greatly reduced, two machining steps are reduced, the machining process for the whole product is optimized, the machining efficiency is improved by 20 percent, the stress concentration during heat treatment is avoided, and machining risks are reduced. The rounding-off of the connecting positions of the side surfaces and the bottom surface of the oil groove ensures that lubricating grease is uniformly attached to the inside of the oil groove, so that the lubrication area is maintained.
Description
Technical field
The utility model relates to a kind of technical field of wind power generation, especially a kind of pivoting support that is used for the accurate oil groove of wind-power electricity generation band.
Background technique
Present existing tank structure is as shown in Figure 1; To the oiling of pivoting support raceway, lubricated and add the complexity in man-hour following deficiency is arranged: receive the restriction of tank structure; 1. when injecting a certain amount of lubricant oil, often need long time; Cause the expenditure of manpower, material resources and financial resources excessive, so that the wasting of resources; 2. in pivoting support uses, because the structure of this oil groove causes interior lubricant grease of oil groove and rolling element area of contact too small, lubricated abundant inadequately; 3. the excessive place of this oil groove and raceway is too sharp-pointed to the raceway heat treatment process time, is prone to cause stress to concentrate, and causes product rejection when serious.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned existing technology; A kind of pivoting support that is used for the accurate oil groove of wind-power electricity generation band is provided, the raceway of this pivoting support and the rounding off of oil groove, and can adapt to the sufficient lubrication raceway; It is simple in structure; Difficulty of processing is low, optimized processing technology, reliability is high, and is more convenient during working service, is easy to promote the use of.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of pivoting support that is used for the accurate oil groove of wind-power electricity generation band comprises oil groove, the raceway joint rounding off of said oil groove and pivoting support, the side of oil groove and joint, bottom surface rounding off.
The width of said oil groove is 11.5mm, and the degree of depth is 21.5mm.The width that it has increased oil groove has reduced the overall depth of oil groove, the lubricant grease that when enlarging logical oil mass, increases and the area of contact of rolling element.
It is big that the width of the utility model oil groove becomes, and when giving the pivoting support oiling, reduced the oiling time, promoted oil injecting speed, reduces the O&M cost.
Stress when the rounding off of raceway and oil groove can prevent heat treatment process is concentrated the damage to raceway, reduces difficulty of processing and product rejection rate.The slyness of raceway and oil groove and the side of oil groove and joint, bottom surface rounding off reduce the pivoting support difficulty of processing greatly; Reduce by two tooling step; Optimized the processing technology of entire product; Improved work efficiency and reached 20%, the stress when having avoided heat treatment is simultaneously concentrated, and has reduced the processing risk.The side of oil groove and joint, bottom surface rounding off make lubricant grease evenly attached in the oil groove, keep lubricated area.
The beneficial effect that the utility model brings is, and is simple in structure, and difficulty of processing is low, optimized processing technology, reliability is high, and is more convenient during working service, is easy to promote the use of.
Description of drawings
Fig. 1 is the structural representation of background technique;
Fig. 2 is the structural representation (sectional view) of the utility model;
Fig. 3 is the schematic perspective view (sectional view) of the utility model;
Wherein 1. raceways, 2. oil groove.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Referring to Fig. 2, Fig. 3, the joint rounding off R2 fillet of raceway 1 and oil groove 2, the side of oil groove 2 and the rounding off of bottom surface are connected the R3 fillet; Wherein R2, R3 two fillets reduce difficulty of processing greatly; Reduce by two tooling step, optimized the processing technology of entire product, improved work efficiency and reached 20%; Stress when having avoided heat treatment is simultaneously concentrated, and has reduced the processing risk; R3 makes lubricant grease evenly attached in the oil groove 2, keeps lubricated area.Increase the width of oil groove 2; Concrete width h2 is 11.5mm, reduces the overall depth of groove, and overall depth is L1:21.5mm; Make it when enlarging logical oil mass, increase the area of contact of lubricant grease and rolling element, make rolling element in movement process, be able to sufficient lubrication.
Though the above-mentioned accompanying drawing that combines is described the embodiment of the utility model; But be not restriction to the utility model protection domain; One of ordinary skill in the art should be understood that; On the basis of the technological scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection domain of the utility model.
Claims (2)
1. a pivoting support that is used for the accurate oil groove of wind-power electricity generation band comprises oil groove, it is characterized in that the raceway joint rounding off of said oil groove and pivoting support, the side of oil groove and joint, bottom surface rounding off.
2. the pivoting support that is used for the accurate oil groove of wind-power electricity generation band as claimed in claim 1 is characterized in that the width of said oil groove is 11.5mm, and the degree of depth is 21.5mm.
