Abstract

The utility model relates to a support roller, in particular to a support roller for a belt conveyor. The support roller comprises a support roller tube, a bearing seat, end covers and a support roller shaft, wherein a bearing is arranged on the support roller shaft arranged in an inner hole of the bearing seat, the two ends of the support roller tube are sealed through the end covers, the bearing seat and the support roller tube are integrally formed, a combined sealing structure formed by an inner sealing ring and an outer sealing ring is arranged in a space formed by the support roller shaft, the bearing and the bearing seat. After the adoption of the structure, the whole support roller has the advantages that the structure is compact, the sealing performance of the support roller is improved, and the service life of the support roller is prolonged. Meanwhile, the support roller tube is made of ADI (austempering ductile cast iron), so the intensity of the support roller is higher, the toughness is higher, and the wear resistance is better.

Description

Supporting roller for belt conveyer

Technical field

The utility model relates to a kind of carrying roller, particularly a kind of supporting roller for belt conveyer.

Background technology

The carrying roller good dustproof effect of using on the belt conveyer at present, but leak tightness and waterproof effect are relatively poor.Because door is squeezed on the bearing chamber inner hole wall, bearing seat arranges separately, so poor sealing performance, Joint strenght is low, and the normal contact of the working environment of carrying roller has water, particularly at the environment of underground work.Water easily infiltrates from the shelves lid, causes bearing failure, causes whole carrying roller to use.

Chinese utility model patent specification sheets CN 201305344Y discloses a kind of carrying roller of belt conveyer, comprise roller supporting tube, bearing chamber, door and roller carrier shaft etc., the outer rim of bearing chamber is connected with the roller supporting tube inwall, and part is stretched out roller supporting tube, bearing is arranged on bearing chamber endoporus centre bearer arranged outside seal ring, the arranged outside of seal ring has door, the external diameter of door is corresponding with bearing chamber outer rim external diameter, the middle part of door is provided with projection, this projection is corresponding with the inner hole of bearing seat size, projection stretches in the bearing chamber endoporus, abut against the seal ring outside, door, bearing chamber is captiveed joint with roller supporting tube and is integral.The utlity model has rational in infrastructure, intensity is high, etc. advantage, but the leak tightness fastness of this utility model carrier roller of belt conveyer is poor.

Summary of the invention

The utility model technical issues that need to address provide a kind of good airproof performance, intensity height, good toughness, carrying roller that wear resisting property is good.

For solving above-mentioned technical matters, the utility model supporting roller for belt conveyer comprises roller supporting tube, bearing seat, end cap and roller carrier shaft, bearing is arranged on the roller carrier shaft in the inner hole of bearing seat, the two ends end cap seal of described roller supporting tube, described bearing seat and roller supporting tube are one-body molded, and the combined sealing structure of inner seal ring and outer seal ring is set in the space that roller carrier shaft, bearing and bearing seat form.

Be provided with oil sealing between described combined sealing structure and the end cap.

Be provided with back-up ring between described combined sealing structure and the oil sealing.

Be provided with rear seal ring between described bearing and the bearing seat.

Described roller supporting tube adopts the ADI spheroidal graphite iron to make.

After adopting said structure, whole idler structure is compact, has improved the leak tightness of carrying roller, has prolonged the service life of carrying roller.Simultaneously, roller supporting tube adopts the ADI spheroidal graphite iron to make, so that the intensity of carrying roller is larger, toughness is higher, and is more wear-resisting.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is structural representation of the present utility model.

Among the figure: 1 is roller supporting tube, and 2 is roller carrier shaft, and 3 is bearing seat, and 4 is bearing, and 5 is end cap, and 6 is inner seal ring, and 7 is outer seal ring, and 8 is oil sealing, and 9 is back-up ring, and 10 is rear seal ring.

The specific embodiment

Supporting roller for belt conveyer as shown in Figure 1 comprises roller supporting tube 1, bearing seat 3, end cap 5 and roller carrier shaft 2.Bearing 4 is arranged on the roller carrier shaft 2 in bearing seat 3 endoporus.The two ends of described roller supporting tube 1 seal with end cap 5, described bearing seat 3 is one-body molded with roller supporting tube 1, integrated like this design can guarantee in roller supporting tube 1 and bearing seat 3 rotation processes synchronously, in long-term use procedure, can guarantee can not produce the slit between roller supporting tube 1 and the bearing seat 3, improve the sealing property of carrier roller integral.The combined sealing structure of inner seal ring 6 and outer seal ring 7 is set in the space that roller carrier shaft 2, bearing 4 and bearing seat 3 form, can better improves like this sealing property of carrying roller.Be provided with oil sealing 8 between described combined sealing structure and the end cap 5, oil sealing 8 can prevent silt, dust, moisture etc. on the one hand from intruding into bearing outward, and the lubricating oil that can limit in the bearing on the other hand exposes.

Be provided with back-up ring 9 between described combined sealing structure and the oil sealing 8.

Be provided with rear seal ring 10 between described bearing 4 and the bearing seat 3.

Described roller supporting tube 1 adopts the ADI spheroidal graphite iron to make, and the ADI spheroidal graphite iron has the following advantages:

1, intensity is high, and plasticity is good

In equal percentage elongation situation, the tensile strength of ADI is 2 times of common spheroidal graphite iron; In the situation of equality strength, its percentage elongation is more than 2 times of common spheroidal graphite iron.

2, quality is light

The part of comparable size is lighter by about 10% than steel, helps the lightweight of product.

3, strength at repeated alternation and fracture toughness and low-alloy steel are suitable

The bending fatigue resistance of ADI and fracture ductility and low-alloy steel are suitable, still can keep 70% Room-temperature Fracture Toughness in the time of-40 ℃.

4, vibration damping is good

ADI contains graphite nodule, thereby can absorb rapidly vibration, makes mechanical vibration trends steadily, and its cushioning performance reduces noise during to transmission and plays an important role; Particularly graphite has lubricating function, and its wear resistance is more high than steel.

So roller supporting tube employing ADI spheroidal graphite iron can be so that carrying roller intensity be larger, toughness is higher, and resistance to abrasion is better.
