Abstract

The invention discloses the cylinder roller bearing of a kind of easy assembling, including inner ring, outer ring, retainer, and be arranged between outer ring and retainer encloses the most uniform cylindrical roller, described retainer is provided with a pair the elastic clamping block matched with cylindrical roller in the inner side of each cylindrical roller correspondence position, the rear end of described elastic clamping block and retainer are fixed together, front end is less than the diameter of cylindrical roller to this bent intermediate to elastic clamping block, the gap of every pair of elastic clamping block front end.The structure of retainer is improved by the present invention, fixture block inside retainer uses elastic construction, so that cylindrical roller is easier to be assembled between retainer and outer ring, cylindrical roller can be carried out auto lock, bearing in use, is generally of certain temperature simultaneously, the elastic clamping block that memorial alloy is made raises along with temperature, its intensity is more preferable, and self-locking property is more preferable, thus improves the life-span of bearing.

Description

A kind of cylinder roller bearing of easy assembling
Technical field
The present invention relates to the cylinder roller bearing of a kind of easy assembling.
Background technology
Cylinder roller bearing includes inner ring, outer ring, retainer and cylindrical roller, and each cylindrical roller is by inside retainer Two symmetrical fixture blocks be stuck between retainer and outer ring, at present, fixture block is all the most one-body molded with retainer, cylinder roll Son dress is as after between retainer and outer ring, by the bending in the middle of cylindrical roller of two symmetrical fixture blocks, so that cylinder rolls Son is stuck between retainer and outer ring without dropping, and such cylinder roller bearing assembles up and more bothers, at fixture block During bending, the requirement to bending technique is higher, amplitude can not too big, can not be the least, thus defect rate is high, and finished product was using Cheng Zhong, fixture block is easily broken off with retainer, and the life-span is the best.
Summary of the invention
For the problems referred to above, the invention provides the cylinder roller bearing of a kind of easy assembling, assembling can not only be simplified Technique, simultaneously it is also possible that fixture block forms auto-lock function to cylindrical roller, improves firmness between fixture block and retainer, no Easy fracture, has preferable thermal diffusivity.
The technical solution used in the present invention is:
The cylinder roller bearing of a kind of easy assembling, including inner ring, outer ring, retainer, and is arranged on outer ring and holding Between frame one encloses the most uniform cylindrical roller, and described retainer is provided with in the inner side of each cylindrical roller correspondence position The elastic clamping block that a pair matches with cylindrical roller, the rear end of described elastic clamping block and retainer are fixed together, front end is to this Bent intermediate to elastic clamping block, the gap of every pair of elastic clamping block front end is less than the diameter of cylindrical roller.
As preferably, described elastic clamping block is that spring steel is made or memorial alloy is made.
As preferably, the inner surface of described elastic clamping block is circular arc, and the internal diameter of this circular arc is not less than cylindrical roller External diameter.
The structure of retainer is improved by the present invention, and the fixture block inside retainer uses elastic construction, so that circle Post roller is easier to be assembled between retainer and outer ring, cylindrical roller can be carried out auto lock simultaneously, and bearing is using In, it being generally of certain temperature, the elastic clamping block that memorial alloy is made raises along with temperature, and its intensity is more preferable, self-locking property More preferably, thus improve the life-span of bearing.
Accompanying drawing explanation
Fig. 1 is the sectional view of the present invention；
Fig. 2 is the side structure schematic diagram of Fig. 1；
In figure: 1. outer ring, 2. inner ring, 3. cylindrical roller, 4. retainer, 5. elastic clamping block.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
As shown in Figure 1, 2, the cylinder roller bearing of a kind of easy assembling, including inner ring 2, outer ring 1, retainer 4, Yi Jian One be contained between outer ring 1 and retainer 4 encloses the most uniform cylindrical roller 3, and described retainer 4 is at each cylindrical roller 3 The inner side of correspondence position is provided with a pair elastic clamping block 5 matched with cylindrical roller 3, the rear end of described elastic clamping block 5 and guarantor Hold frame 4 be fixed together, front end to this bent intermediate to elastic clamping block 5, the gap of every pair of elastic clamping block 5 front end is less than cylinder The diameter of roller 3.
Described elastic clamping block 5 makes for spring steel or memorial alloy is made.
The inner surface of described elastic clamping block 5 is circular arc, and the internal diameter of this circular arc is not less than the external diameter of cylindrical roller 3.
The assembly method of the bearing of elastic clamping block employing memorial alloy is as follows: 1. retainer is installed to the inner side of outer ring； 2., in the environment of retainer and outer ring being positioned below memorial alloy transition temperature, move elastic clamping block so that cylindrical roller energy Enough between the inner side of retainer loading retainer and outer ring；3. cylindrical roller is encased between retainer and outer ring, cylinder After roller all assembles, return under room temperature；4. inner ring is assembled to the inner side of retainer, completes the assembling of bearing.
Memorial alloy selects the transition temperature memorial alloy less than 0 DEG C.
The assembly method of the bearing of elastic clamping block employing spring steel is as follows: 1. retainer is installed to the inner side of outer ring；2. Move the elastic clamping block inside retainer so that cylindrical roller can load between retainer and outer ring from the inner side of retainer； 3. being encased between retainer and outer ring by cylindrical roller, unclamp elastic clamping block, elastic clamping block restores to the original state and is locked by cylindrical roller Between retainer and outer ring；4. inner ring is assembled to the inner side of retainer, completes the assembling of bearing.
