Description
Technical field
The utility model relates to engineering machinery technical field of bearings, is specially a kind of engineering machinery vehicle bridge special cylindrical roller bearing structure.
Background technique
Engineering machinery is the important component part of China's manufacturing, be with fastest developing speed in China's manufacturing industry, development steadily, economic benefit and produce market prospect better and become the competition of experience entry to WTO in advance and formed the industry having stronger competitive capacity with external product, in China's manufacturing industry, occupy critical role.In order to tackle the competition of Foreign Engineering Machinery enterprise, key is on the basis of accomplishing to know yourself as well as the enemy to world's engineering machinery development trend and international competition opponent, improve the product of China's engineering machinery industry, the international competitiveness of enterprise and industry, therefore the development trend research of engineering machinery is had great importance, along with modernization construction paces quickening, engineering machinery is to seriation, while maximization future development, always also to multi-functional, the future development of light, require self-contained bearing compact structure, smooth running, can lean on, load bearing capacity is large, life-span is long, completely fill thin-walled and be used for engineering machinery vehicle bridge Planetary Gear Transmission without outer ring Biserial cylindrical roller bearing.
Chinese patent CN103790948A describes a kind of roller bearing, this bearing unit comprises inner ring, retainer and rolling element, two eccentric raceways are provided with outside inner ring, rolling element is fastened on two raceways of inner ring, retainer is located at the both sides of raceway, the centre of inner ring is provided with an endoporus shared by two raceways, the both sides of raceway are equipped with rib, compared with prior art, the utility model replaces common double line column roller bearing, axle is made to manufacture eccentric shaft, be convenient to install, but this has also reduced bearing pressure and greatly reducing the working life of bearing of bearing, but the connection defective tightness between existing bearing structure, working life is short, manufacturability is poor, part weight weight, therefore, a kind of engineering machinery vehicle bridge special cylindrical roller bearing structure is proposed.
Prior art can not meet the needs of people, for making up prior art deficiency, it is strong that the utility model aims to provide the simple ability to bear of a kind of structure, achieve the optimal design of bearing, the ability to bear designed by rule of thumb than conventional machinery gear mechanism adds 9.6%, be conducive to reducing tiltedly error partially, homogeneous structure is compact more for roller and inner ring distribution of contact, the engineering machinery vehicle bridge special cylindrical roller bearing structure that the Q-percentile life that operates steadily is long.
For achieving the above object, the utility model provides following technological scheme: a kind of engineering machinery vehicle bridge special cylindrical roller bearing structure, comprises roller, inner ring, back-up ring, spring collar, paper web, planetary pinion and sun gear; Described roller is symmetricly set on inner ring outer surface, and is connected between roller and inner ring; Described spring collar is arranged in the middle of back-up ring, and spring collar two ends and paper web and inner ring compact siro spinning technology; Described back-up ring is arranged between spring collar and roller, and back-up ring and the adhesion of roller sidewall; Face and planetary pinion compact siro spinning technology outside described paper web; Compact siro spinning technology between described planetary pinion outer surface and sun gear inside.
Preferably, described roller is arranged between inner ring and paper web, and is convex structure.
Preferably, described spring collar is helical structure.
Preferably, described spring collar is shrinking structure.
Preferably, be threaded between described planetary pinion and sun gear.
Preferably, described roller is cylindrical structural.
Preferably, described planetary inner side and bearing roller pass through pinned connection.
Compared with prior art, the beneficial effects of the utility model are: this structure is simple, paper web and bearing inner race are fixed together, effectively prevent roller to come off, because full dress roller bearing mechanical characteristic is poor, therefore adopt surface-treated roller, improve the contact condition with its surface, improve the service behaviour of bearing.Adopt the logarithm of convex design element line roller to reduce stress to concentrate, this structure installment space is little; thin-walled is without cup roller new structure, and rational circumference total backlash ε makes bearing structure steady, decreases wearing and tearing; add the life-span; reasonably bearing end-play Cr improves bearing load distribution, and carrying uniformity, has stronger bearing capacity; improve the usability of this structure on a large scale, be applicable to promoting the use of.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, the utility model provides a kind of technological scheme: a kind of engineering machinery vehicle bridge special cylindrical roller bearing structure, comprises roller 1, inner ring 2, back-up ring 3, spring collar 4, paper web 5, planetary pinion 6 and sun gear 7; Described roller 1 is symmetricly set on inner ring 2 outer surface, and is connected between roller 1 and inner ring 2; Described spring collar 4 is arranged in the middle of back-up ring 3, and spring collar 4 two ends and paper web 5 and inner ring 2 compact siro spinning technology; Described back-up ring 3 is arranged between spring collar 4 and roller 1, and back-up ring 3 and the adhesion of roller 1 sidewall; Face and planetary pinion 6 compact siro spinning technology outside described paper web 5; Compact siro spinning technology between described planetary pinion 6 outer surface and sun gear 7 inside.
The utility model optimisation technique scheme, described roller 1 is arranged between inner ring 2 and paper web 5, and is convex structure; Described spring collar 4 is helical structure; Described spring collar 4 is shrinking structure; Be threaded between described planetary pinion 6 and sun gear 7; Described roller 1 is cylindrical structural; Inner side and the bearing roller 1 of described planetary pinion 6 pass through pinned connection.
As working principle of the present utility model: not high according to engineering machinery vehicle bridge planetary gear bearing rotating speed, radial load is larger, bear certain impact, the operating mode that installing space is less, have employed the full dress thin-walled Biserial cylindrical roller bearing of more too load bearing capacity, compared with band retainer bearing, the dynamics completely filling roller bearing is poor, because in working procedure, the working surface of adjacent rollers directly contacts, and move in the opposite direction, therefore this motion has rolling and certain slip concurrently, roll and certain slip, therefore, contacting point between roller is difficult to form effective lubricant film, contact friction between roller wants high times compared with the situation of retainer and roller contact, therefore, under certain operating conditions, the friction of bearing is larger, temperature is higher, in the application that some are important, surface-treated roller can be adopted, to improve the contact condition of roller surface, improve the service behaviour of bearing, the bearing capacity of bearing is greatly improved, substantially the usage requirement of engineering machinery vehicle bridge main frame is met.
