Abstract

The utility model discloses a novel labyrinth seal carrier roller which comprises roller skin, a carrier roller shaft, a bearing seat, a bearing, a labyrinth combined seal ring, a sealing ring, an end cover and a shaft washer. The bearing seat is arranged in the roller skin and is in clearance fit with the roller skin, the bearing is arranged in the bearing seat and is in clearance fit with the bearing seat, the bearing is in clearance fit with the carrier roller shaft, the labyrinth combined seal ring is in clearance fit with the bearing seat and the carrier roller shaft, the sealing ring is arranged outside the labyrinth combined seal ring, the end cover is arranged in the bearing seat and is in clearance fit with the carrier roller shaft, and the shaft washer is arranged outside the end cover and located in a groove of the carrier roller shaft. The novel labyrinth seal carrier roller is reasonable in structure, safe, reliable, high in wear resistance, low in weight, little in rotation resistance, flexible in rotation, good in sealing performance and capable of effectively preventing dust and water, and the service life of the carrier roller is prolonged.

Description

Novel labyrinth seal carrying roller
Technical field
The utility model relates to a kind of novel labyrinth seal carrying roller.
Background technology
Carrying roller is the vitals of belt conveyer, and kind is many, and quantity is large.It has accounted for 35% of a belt conveyer total cost, has born more than 70% resistance, and therefore the quality of carrying roller is particularly important.
The effect of carrying roller is support belt and weight of material.Carrying roller running must flexibility and reliability.Reduce load-transfer device with the friction force of carrying roller, the life-span that accounts for more than 25% load-transfer device of conveyer total cost is played to key role.Although carrying roller is a small parts in belt conveyer, structure is also uncomplicated, produces special quality carrying roller not a duck soup.
Novel labyrinth seal idler structure of the present utility model is reasonable, safe and reliable, and resistance to abrasion is strong, and quality is light, and rotational resistance is little, and carrying roller rotates flexibly, and good airproof performance can actv. dustproof and waterproof, has extended the service life of carrying roller.
Summary of the invention
The purpose of this utility model is to provide a kind of novel labyrinth seal carrying roller.
The purpose of this utility model is achieved through the following technical solutions:
Novel labyrinth seal carrying roller of the present utility model, comprises roller skin, roller carrier shaft, bearing seat, bearing, labyrinth combined seal ring, seal ring, end cap and shaft block ring.Bearing seat is located at roller intracutaneous, bearing seat and roller skin interference fit, bearing is located in bearing seat, bearing and bearing seat interference fit, bearing and roller carrier shaft interference fit, labyrinth combined seal ring and bearing seat interference fit, labyrinth combined seal ring and roller carrier shaft interference fit, seal ring is located at combined seal ring outside, labyrinth, end cap is located in bearing seat, end cap and roller carrier shaft interference fit, shaft block ring is located at end cap outside, and shaft block ring is located in the groove of roller carrier shaft.
The technical scheme being provided by above-mentioned the utility model can be found out, novel labyrinth seal carrying roller described in the utility model, rational in infrastructure, safe and reliable, resistance to abrasion is strong, quality is light, rotational resistance is little, and carrying roller rotates flexibly, good airproof performance, can actv. dustproof and waterproof, extended the service life of carrying roller.
Accompanying drawing explanation
Fig. 1 is novel labyrinth seal idler structure schematic diagram;
Fig. 2 is I place partial enlarged drawing.
The specific embodiment
Novel labyrinth seal carrying roller of the present utility model, its preferably the specific embodiment as shown in Figure 1 and Figure 2, novel labyrinth seal carrying roller comprises roller skin 1, roller carrier shaft 2, bearing seat 3, bearing 4, labyrinth combined seal ring 5, seal ring 6, end cap 7 and shaft block ring 8.
Bearing seat 3 is located in roller skin 1, bearing seat 3 and roller skin 1 interference fit, bearing 4 is located in bearing seat 3, bearing 4 and bearing seat 3 interference fit, bearing 4 and roller carrier shaft 2 interference fit, labyrinth combined seal ring 5 and bearing seat 3 interference fit, labyrinth combined seal ring 5 and roller carrier shaft 2 interference fit, seal ring 6 is located at labyrinth combined seal ring 5 outsides, end cap 7 is located in bearing seat 3, end cap 7 and roller carrier shaft 2 interference fit, shaft block ring 8 is located at end cap 7 outsides, and shaft block ring 8 is located in the groove of roller carrier shaft 2.
Novel labyrinth seal carrying roller of the present utility model has following innovative point:
Novel labyrinth seal carrying roller is provided with V-shaped seal ring, dustproof and waterproof effectively, and actv. has extended the service life of carrying roller;
Between the seal ring of novel labyrinth seal carrying roller and shaft block ring, there is effective positive pressure, prevent that dust from entering, extended the service life of carrying roller.
Beneficial effect of the present invention
Rational in infrastructure, safe and reliable;
Resistance to abrasion is strong, and quality is light;
Rotational resistance is little, and carrying roller rotates flexibly;
Good airproof performance, can actv. dustproof and waterproof, has extended the service life of carrying roller.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
