Description
Technical field
The utility model relates to a kind of labyrinth packing 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.
Labyrinth packing 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 labyrinth packing carrying roller.
The purpose of this utility model is achieved through the following technical solutions:
Labyrinth packing carrying roller of the present utility model, comprises roller skin, roller carrier shaft, bearing seat, bearing, labyrinth combined seal ring, back-up ring, profile of tooth seal ring and exterior seal 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, back-up ring is located at labyrinth seal outside, back-up ring and bearing seat interference fit, back-up ring is provided with groove, profile of tooth seal ring is located in the groove of back-up ring, profile of tooth seal ring and back-up ring interference fit, exterior seal ring is provided with groove, profile of tooth seal ring is located in the groove of exterior seal ring, exterior seal ring and roller carrier shaft interference fit.
The technical scheme being provided by above-mentioned the utility model can be found out, labyrinth packing carrying roller described in the utility model is rational in infrastructure, safe and reliable, resistance to abrasion is strong, and quality is light, and 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.
Brief description of the drawings
Fig. 1 is labyrinth packing idler structure schematic diagram;
Fig. 2 is I place partial enlarged drawing.
Detailed description of the invention
Labyrinth packing carrying roller of the present utility model, its preferably detailed description of the invention as shown in Figure 1 and Figure 2, labyrinth packing carrying roller comprises roller skin 1, roller carrier shaft 2, bearing seat 3, bearing 4, labyrinth combined seal ring 5, back-up ring 6, profile of tooth seal ring 7 and exterior seal 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, back-up ring 6 is located at labyrinth seal 5 outsides, back-up ring 6 and bearing seat 3 interference fit, back-up ring 6 is provided with groove, profile of tooth seal ring 7 is located in the groove of back-up ring 6, profile of tooth seal ring 7 and back-up ring 6 interference fit, exterior seal ring 8 is provided with groove, profile of tooth seal ring 7 is located in the groove of exterior seal ring 8, exterior seal ring 8 and roller carrier shaft 2 interference fit, profile of tooth seal ring 7 is provided with three detent projection 9.
Labyrinth packing carrying roller of the present utility model has following innovative point:
The profile of tooth seal ring of labyrinth packing carrying roller is provided with three detent projection, also can in carrying roller rotary course, utilize centnifugal force to be thrown away even if the impurity such as water dust enter profile of tooth seal ring, and actv. has extended the service life of carrying roller.
the beneficial effects of the utility model are:
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 preferably detailed description of the invention 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.
