Abstract
The utility model relates to a roller overrunning clutch, which is characterized in that: the roller overrunning clutch comprises an outer ring gear, an intermediate shaft gear which is connected with an inner ring cam and a gland bush through bolts, a cage which is sleeved outside the inner ring cam, and a roller which is arranged inside a race of the inner ring gear, wherein, the roller takes the shape of a drum, the diameter on both ends of the roller is smaller than that of the central section, and the drum-shaped size H formed by the diameter on both ends and the diameter on the central section is between 0.003 and 0.05 millimeters. The roller overrunning clutch has the advantages that: the roller adopts the drum-shaped structure, thereby the roller overrunning clutch can obviously improve the contact status between the roller and the race and the cage and simultaneously can greatly reduce the edge effect of contact stress between the roller and the race and effectively improve the distribution uniformity of contact stress of a contact pair, consequently avoiding early abrasion of the roller and the cage and having great significance in improving the operation reliability and the stability of an engineering mechanical gear box.
Description
Technical field
The utility model relates to engineering machinery transmission device technical field, and especially a kind of being used for realizes throwing off the roller overrunning clutch of low speed wedging transmitting large torque at a high speed.
Background technique
At present, the utilization of free wheel device in engineering machinery transmission device technical field is quite general, its structure is mainly by outer ring gear, countershaft-gear by bolt and interior ring cam and gland connection, be sleeved on the outer retainer of interior ring cam, and the interior roller of raceway of ring cam constitutes in being contained in.The interior raceway of interior ring cam and outer ring gear forms the wedge space, retainer makes correct the remaining in the wedge space of roller, spring is installed in the end face groove of retainer, one end withstands retainer, the other end withstands on the gland, make retainer promote the little end motion of roller together, outer ring gear and interior ring cam wedging are in the same place towards the wedge space, and transferring power and moment of torsion etc.Employed roller mainly is a linear type cylinder roller in the free wheel device of this structure, mainly has following defective: the contact strength deficiency between (1) Contact Pair, cause free wheel device shorter working life; (2) roller that uses of free wheel device is linear type cylinder roller, and resiliently deformable and juxtaposition metamorphose after taking place in linear type cylinder roller, mainly exist contact stress seriously bigger than normal, even surpass the limit contact stress that part can bear in the Contact Pair, cause its damage at two ends; (3) because each part in manufacturing and installation process, exists relevant coaxality and perpendicularity equal error, make each roller unbalance stress, roller tilts, and causes roller load to occur being partial to, and roller and retainer produce premature wear.
Summary of the invention
It is more reasonable that the purpose of this utility model just provides a kind of structure, and can effectively improve the roller overrunning clutch in working life.
Solution of the present utility model is such: include outer ring gear, countershaft-gear by bolt and interior ring cam and gland connection, the outer retainer of ring cam in being sleeved on, and the roller in the ring cam race in being contained in, described roller is to be the cydariform of two ends diameter less than the middle part diameter, and the cydariform amount H that its two ends diameter and middle part diameter form is 0.003～0.05mm.
In such scheme, the cydariform curve of described cydariform roller can be to be two ends to adopt the straight line adverse slope, and is middle with circular arc line transition shape; The cydariform curve of described cydariform roller can be to be the circular arc wire; The cydariform curve of described cydariform roller can be to be the elliptic curve shape; The cydariform curve of described cydariform roller can be that an end is the class elliptic curve, and the other end adopts the straight line adverse slope, and is middle with circular arc line transition shape; The cydariform curve of described cydariform roller can be that an end is the class elliptic curve, and the other end adopts and is circular arc line, and is middle with circular arc line transition shape; The cydariform curve of described roller can be to be class elliptic curve shape.
The utility model is compared with existing similar technology and had the following advantages: (1) roller adopts drum organization, and the part contact stress in the Contact Pair is evenly distributed, and effectively reduces the edge effect of its contact stress.(2) roller adopts drum organization, has improved because in manufacturing and the installation process, the relevant coaxality of existence and the deflection load of roller that the error of perpendicularity causes have avoided roller and retainer to produce premature wear.(3) roller adopts drum organization, surmounts under the revolution situation at a high speed, has overcome when surmounting running at a high speed the roller very fast shortcoming of wearing and tearing.(4) roller adopts drum organization evenly to bear load, has improved the functional reliability of free wheel device.
