Abstract
The utility model discloses a steel shaft nylon carrier roller, comprising a carrier roller shaft, a bearing, a shaft block, a labyrinth and a housing, wherein the shaft block and the housing are made of PA nylon material, the carrier roller shaft adopts a 35<#> steel shaft, the labyrinth is made of the PA nylon material and consists of an internal seal and an external seal which are engaged crossways, the outer side of the labyrinth is provided with an external nylon catch cover, a steel protective sleeve is arranged between the labyrinth and a steel protective cover, an internal snap spring is arranged between the bearing and the labyrinth, and the outer side of the external nylon catch cover is provided with an external snap spring. The steel shaft nylon carrier roller improves the carrier roller quality by changing the material and the sealing structure of certain parts, and has the characteristics of light weight, small operating resistance, small radial runout, small abrasion on a tape, long service life and corrosion resistance, and the like.
Description
Technical field:
The utility model relates to the device on the mechanical conveyor, specifically a kind of carrying roller.
Background technology:
At present, carrying roller commonly used is divided into three kinds of common carrying rollers, full nylon carrying roller, carrier roller by material.Common carrying roller (except that the seal ring material is nylon or plastics, other parts be steel matter) is withstanding corrosion, unreliable, the incompatibility harsh environment of sealing not; Full nylon carrying roller intensity is low, radial runout big, the spindle nose easy fracture, as application number is; And carrier roller is difficult for processing, running resistance big (the roller skin is wayward with the concentricity of axle, technological reason due to).Therefore, people improve the performance of carrying roller by changing each parts material usually, are that 200520030198.4 Chinese patent discloses a kind of " belt transporter carrying roller nylined bearing seat " as the patent No., adopt nylon material to make bearing seat; The patent No. is 02222216.2 Chinese patent open " a kind of novel carrying roller ", be that plain bearing is adopted the monomer cast nylon manufacturing, all be that the not withstanding corrosion, the sealing that utilize the characteristic of nylon itself to solve general holder carrying roller to exist are unreliable, but other problem change effect not clearly.
The utility model content:
Technical problem to be solved in the utility model provides a kind of steel axle nylon carrying roller at above deficiency exactly, this carrying roller has overcome the deficiency of common carrying roller and nylon carrying roller, absorbed the advantage of common carrying roller and nylon carrying roller, had that carrying roller is in light weight, running resistance is little, radial runout is little, advantages such as, long service life little, withstanding corrosion the adhesive tape wearing and tearing.
Technical solution adopted in the utility model is:
A kind of steel axle nylon carrying roller comprises roller carrier shaft, bearing, bearing seat, labyrinth and shell, and wherein: bearing seat and shell all adopt the PA nylon material, so carrying roller is in light weight, the resistance to abrasion height, and the life-span is long.
Roller carrier shaft adopts 35
#The steel axle, intensity height, easily processing.
Make for the PA nylon material in the labyrinth, stings wrong interior sealing and outer gland sealing together by intersection and form, and makes that muddy water is difficult for entering, and has prolonged service life.
The outside in labyrinth also is provided with the outer door of nylon, is that water and dust are difficult for entering, and has prolonged service life and rotational resistance and has reduced.
Has the steel protecting sleeve between labyrinth and the steel over cap, to prevent the hermetically-sealed construction distortion, to lose efficacy.
Be provided with interior jump ring between bearing and the labyrinth, the outside of the outer door of nylon is provided with the wild card Huang, to strengthen endplay control.
The beneficial effect that the utility model can reach is:
1, the utility model has improved the carrying roller quality by changing the material and the hermetically-sealed construction of a limiting-members, has prolonged the service life of carrying roller.
2, the utlity model has in light weight, characteristics such as running resistance is little, radial runout is little,, long service life little to adhesive tape wearing and tearing, withstanding corrosion, be more than 3 times of common carrying roller service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1: a kind of steel axle nylon carrying roller, adopt PA nylined bearing seat 4 to replace conventional cast bearing seat 4; Adopt PA nylon (high abrasion) tubing shell 3 to replace solid drawn pipe shell 3; Utilize the intensity of steel protecting sleeve 6 and the self-lubricating property of PA nylon, adopt to intersect and sting the mistake interior sealing 8 together and the labyrinth packing of outer gland sealing 7 formations; Roller carrier shaft 2 adopts 35
#The steel axle, bearing 10 is a standard rolling bearing.
Wherein PA nylon outer shell 3 has high-wearing feature, and the roller skin life-span is long, and the material of roller carrier shaft 2 adopts 35 of intensity height, easy processing
#Steel; closely cooperate by outer door 5, labyrinth packing and roller carrier shaft 2 in the hermetically-sealed construction, steel protecting sleeve 6, labyrinth packing and the shell 3 twice fail-safe structure that closely cooperates makes water and dust be difficult for entering; prolonged the life-span of bearing, roller revolving resistance is reduced.By cooperatively interacting between roller carrier shaft 2, bearing 10, bearing seat 4, the PA nylon pipe shell 3, control the carrying roller diameter clearance; Endplay by four jump rings (outer jump ring 1 and interior jump ring 9 each two) control carrying roller.
