Abstract
The utility model relates to a roller pin sleeve assembly, which can achieve the advantages of time and labor conservation, and mounting quality improvement when roller pins in the sleeve are mounted. The roller pin sleeve assembly is characterized by comprising an inner sleeve, an outer sleeve and an adjusting washer, wherein the inner sleeve is sleeved with the outer sleeve; two circles of roller pins are arranged between the inner sleeve and the outer sleeve in the axial direction of the sleeve; the adjusting washer is arranged between the two circles of roller pins in a sleeving manner; preferably, the shaft diameter of the inner sleeve is 31-40 mm, the shaft diameter of the outer sleeve is 40-50 mm, and the number of each circle of roller pins is 20-30; the axial length of the inner sleeve is equal to that of the outer sleeve; and the sum of the cross sections of the two circles of roller pins and the adjusting washer is larger than the axial length of the sleeve; and both the inner sleeve and the outer sleeve are made of plastics.
Description
Technical field
The utility model relates to a kind of packaging structure, and particularly a kind of packing has the sleeve assembly of needle roller in the needle bearing.
Background technology
Need to assemble singly after the common needle roller buying, concrete, between planet wheel spindle and planetary wheel, pack into one the circle needle roller after, be inserted in the adjustment packing ring, reinstall a circle needle roller, smear grease, do not adopt special-purpose packing because needle roller is in bulk, comparatively complicated when making the assembling needle roller, it is time-consuming to take the people, and the loss after sale that causes owing to needle roller is in different size is many.
The utility model content
At deficiency of the prior art, the utility model aims to provide a kind of needle roller sleeve assembly, is arranged on the interior needle roller of this sleeve when mounted, and it is time saving and energy saving to have, and improves the advantage of installation quality.
In order to address the above problem, this kind needle roller sleeve assembly is characterized in that comprising: inner sleeve, outer sleeve and adjustment packing ring; Inner sleeve is set in the outer sleeve, is axially arranged with two circle needle rollers along sleeve between inner sleeve and the outer sleeve, and the adjusting pad snare is located between the two circle needle rollers.
Preferably, the diameter of axle of described inner sleeve is 31mm～40mm; The diameter of axle of described outer sleeve is 40mm～50mm; The quantity of every circle needle roller is 20～30.
Preferably, the axial length of described inner sleeve and outer sleeve equates, and described two circle needle rollers and adjusting pad ring cross-section length sum are greater than the sleeve axial length.
More preferably, described inner sleeve and outer sleeve are made of plastics.
The beneficial effects of the utility model are: the utility model adopts inside and outside plastic sleeve structure, the needle roller size is simply divided into groups, directly be fitted in the plastic sleeve, during installation, by a simple press-fitting tool, just can assemble needle roller by fast speed, plastic sleeve removes by frock, saves the operating time, reduces running cost, improve and press-fit quality, the loss after sale that reduction causes owing to needle roller is in different size.
Description of drawings
Fig. 1 is the perspective view of needle roller sleeve assembly of the present utility model;
Fig. 2 is the sectional structure scheme drawing of needle roller sleeve assembly of the present utility model;
Fig. 3 is the sectional structure side-looking structural representation of needle roller sleeve assembly of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
In conjunction with Fig. 1 to Fig. 3, this kind needle roller sleeve assembly, it comprises: inner sleeve 1, outer sleeve 2 and adjustment packing ring 3.Inner sleeve 1 is set in the outer sleeve 2, is axially arranged with two circle needle rollers 4 along sleeve between inner sleeve and the outer sleeve, adjusts packing ring 3 and is set between the two circle needle rollers.Preferably, the diameter of axle d of inner sleeve 1 is 31mm～40mm, and the diameter of axle of itself and planet wheel spindle is corresponding, the diameter of axle D of outer sleeve 2 is 40mm～50mm, make the gap width between the inner and outer sleeves be about the diameter of axle width of needle roller, the quantity of every circle needle roller is 20～30,40～60 altogether of two circle needle rollers.In addition, the axial length of described inner sleeve 1 and outer sleeve 2 equates, and described two the circle needle rollers 4 and between adjustment packing ring 3 cross-sectional length sums be slightly larger than each sleeve axial length, make an end of needle roller stretch out one section from sleeve, be easy to assembling more, described inner sleeve 1 and outer sleeve 2 are made by plastics.
The utility model adopts inside and outside plastic sleeve structure, the needle roller size is simply divided into groups, directly be fitted in the plastic sleeve, during installation, by a simple press-fitting tool, just can assemble needle roller by fast speed, plastic sleeve removes by frock, saves the operating time, reduces running cost, improve and press-fit quality, the loss after sale that reduction causes owing to needle roller is in different size.
