Abstract
The utility model belongs to the conveying machinery field and particularly relates to a labyrinth nylon carrier roller. The carrier roller comprises a roll, a shaft, a bearing support, a bearing, a clamp spring, a labyrinth sealing sleeve and a labyrinth sealing cover, wherein the roll is assembled with the shaft, the bearing and the clamp spring by the bearing support; and a pair of the labyrinth sealing sleeve and the labyrinth sealing cover that are provided with labyrinth seal are arranged between the bearing and the bearing support. The labyrinth nylon carrier roller has the advantages of convenient processing and manufacturing, good sealing effect, effective water and dust proof, strong corrosion resistant, light weight and long service life; no sparkle is generated in the running process; and the carrier roller is suitable for wide promotion and application.
Description
Technical field
The utility model belongs to the conveying machinery field, particularly a kind of labyrinth type nylon carrying roller.
Background technology
Existing conveying machinery carrying roller, what major part adopted is the steel carrying roller.The steel carrying roller exists certain structures in the mill and can design, but the problem that is difficult for processing, restricting the employing of new construction, simultaneously, the steel carrying roller in use also exist Heavy Weight, not withstanding corrosion, waterproof anti-gray weak effect, can produce spark in operational process and when hard thing collision is arranged and bring shortcomings such as major hidden danger to safety in production.
Summary of the invention
The purpose of this utility model just is to overcome weak point of the prior art, and a kind of Workpiece structure complexity is provided, good sealing effect, withstand corrosion, lightweight nylon carrying roller.
The purpose of this utility model is to realize like this, it comprises: roller, axle, bearing seat, bearing, jump ring, labyrinth gland, labyrinth seal lid, cylinder fits together by bearing seat and axle, bearing, jump ring, is provided with a pair of labyrinth gland, the labyrinth seal lid that has labyrinth seal between bearing and the bearing seat.
The bearing seat of above-mentioned labyrinth type nylon carrying roller is to have end height to be the H section, and the M of its H section-M cross-sectional plane appearance is a profile of tooth, and the endoporus bottom is provided with oilway.
One bottom portion of the labyrinth gland of above-mentioned labyrinth type nylon carrying roller is provided with oilway, and other end outer wall top is that radius is the semicircle sealing shroud of R.
The lid of the labyrinth seal lid of above-mentioned labyrinth type nylon carrying roller is the semicircle sealing shroud of R along the twice radius is arranged.
Between the bearing seat of above-mentioned labyrinth type nylon carrying roller and cylinder, bearing, the labyrinth gland close fit,
Between the bearing of above-mentioned labyrinth type nylon carrying roller and axle, the labyrinth seal lid is close fit.
The cylinder of above-mentioned labyrinth type nylon carrying roller, bearing seat, labyrinth gland, labyrinth seal lid all adopt nylon material to make.
Bearing seat of the present utility model, labyrinth gland, labyrinth seal lid, cylinder all adopt nylon material to make, because it is convenient that this material has forming work, wear-resisting, withstanding corrosion, characteristics such as in light weight, so with prior art now than, the utility model convenient processing and manufacture, good sealing effect, effectively waterproof anti-gray, withstanding corrosion, in light weight, long service life, in operational process, do not sparkle, be suitable for extensively promoting the use of.
