Abstract
The utility model discloses a double-row steel ball roller without a support frame, which is especially suitable for a chain-type conveying machine. The roller is composed of an inner ring, an outer ring, an inner sleeve, etc. The utility model is characterized in that the outer ring is used as a roller body, and a rolling track for mounting a steel ball is arranged between the outer ring and the inner ring; the inner ring is made into a sectional type, and the sections are connected and fixed through the inner sleeve. The roller avoids the defects by adopting a standard bearing to manufacture a roller, such as low carrying capacity, unsuitability for high-temperature zone operation, low manufacture cost, etc.
Description
The utility model relates to the roller of using on a kind of no bracing frame biserial the steel ball roller, particularly chain-linked conveyer tool.
In the prior art, mostly the roller that the chain-linked conveyer tool uses is a minute body structure, being about to two dish standard rolling bearings is installed on the roll body, because the steel ball of standard rolling bearing is fixed with bracing frame, and play is little, so load-carrying capacity is low, also be not suitable in high-temperature zone, using, in addition, use standard rolling bearing to make roller, its cost of product is higher.
The purpose of this utility model is at the deficiencies in the prior art, and it is one that a kind of bearing and roll body are provided, and both can improve load-carrying capacity, can suit again at the no bracing frame biserial steel ball roller of high-temperature zone operation.
The purpose of this utility model can reach by following measure, as shown in the figure, the roller of forming by outer shroud 1, interior ring 3, interior cover 4, steel ball 2 etc., it is characterized in that as being provided with two raceways between the outer shroud 1 of roll body and the interior ring 3, be used to install steel ball 2, interior ring 3 then is divided into three sections, and it is connected and fixed by interior cover 4, on interior ring 3 and interior cover 4, open an oil hole that is communicated with 5, at the two ends of roller with cover of dust 6 sealings.
Compared with prior art, the utlity model has rational in infrastructurely, low cost of manufacture can improve load-carrying capacity, suit in advantages such as high-temperature zone operations.
Accompanying drawing is the utility model structural representation.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further, as shown in the figure, scantling of structure of the present utility model can design as required, interior ring 3 is divided into three sections, and section should be in the junction, center of steel ball 2 with the junction of section, and interior ring grinds by interior cover answers the non-loosening phenomenon after riveting is connected and fixed, outer shroud should rotate freely, roller after the assembling, its end-play is at 0.06-0.12(mm), end-play is at 0.3-0.85(mm) between.
Claims (3)
1, a kind of no bracing frame biserial steel ball roller, it is made up of outer shroud, interior ring, interior cover and steel ball etc., it is characterized in that outer shroud as roll body, offers the raceway that steel ball is installed between it and the interior ring, and interior ring is divided into 3 sections, and connects fixing by interior cover.
2, roller according to claim 1 is characterized in that the steel ball rolling channel between the inner and outer ring has two.
3, roller according to claim 1 is characterized in that being divided into 3 sections interior ring, and the junction between its section and the section is at the line place at steel ball center.
