Abstract

The invention provides a sectional type carrier roller, comprising a carrier roller body and a carrier roller shaft. The sectional type carrier roller is characterized in that the carrier roller body is a short roller body, the short roller body is internally provided with a bearing block, the bearing block is provided with a bearing which is connected with the carrier roller shaft in an approaching way, and multiple carrier roller bodies are connected on the carrier roller shaft in series. In the invention, the traditional one-section carrier roller is changed into a multi-section carrier roller, and multiple short carrier roller bodies are connected on one carrier roller shaft in series for use. The sectional type carrier roller provided by the invention has the advantages that the stress state of the carrier roller is completely changed, a force born by the roller body is directly applied to the shaft, the short carrier roller body can not be bent or deformed, the bearing structure in the short carrier roller body has no concentricity problem, and no 'jamming' is caused; and the wear rate of the short carrier roller provided by the invention is low, the service life is long, the carrier roller can not be frequently replaced, a belt is protected, and the working efficiency of the whole transmission machine equipment is improved.

Description

The sectional type carrying roller

Technical field

The present invention relates to a kind of sectional type carrying roller, belong to the belt transporting facility accessory.

Background technology

Because carrying roller is main load-carrying, a transmission part on the conveyer, so whether its quality quality, running directly have influence on the work efficiency of whole equipment freely.Present modal problem is that stuck phenomenon is not changeed in the easy generation of carrying roller, this mainly is because the structure of existing carrying roller all is the hollow roll body structure by the bearings at both ends seat supports, length is longer, the concentricity requirement that adds bearings at both ends in man-hour (with the roller carrier shaft of centre) is than higher, and transmit and reason such as load carrying ability is big owing to long-time, the carrying roller roll body very easily causes roll body distortion or roller carrier shaft distortion because of vibration or external impacts, make the bearing disalignment at two ends in the roll body, " not dead " phenomenon takes place, stall, the carrying roller that damages needs in time to change, otherwise the belt conveyor above the meeting severe wear influences work efficiency.

Summary of the invention

The objective of the invention is to address the above problem, the sectional type carrying roller that a kind of requirement on machining accuracy is low, simple in structure, stuck phenomenon can not take place is provided.

Technical scheme of the present invention is: a kind of sectional type carrying roller, have carrying roller roll body and roller carrier shaft, and characteristics are, the carrying roller roll body is the short roller body, be provided with bearing seat in the short roller body, bearing seat is provided with bearing and roller carrier shaft is abutted against, and a plurality of carrying roller roll bodies are connected on the roller carrier shaft and use.

A bearing can be set in the above-mentioned bearing seat, two adjacent very near bearings also can be set.

The technology of the present invention changes over the multi-section type carrying roller with an existing joint formula carrying roller exactly, is about to a plurality of short carrying roller roll bodies and is connected on the roller carrier shaft and uses.Compared with the prior art this structure has very outstanding advantage and obvious improvement:

(1) changed the strained condition of carrying roller fully, the suffered power of roll body is applied directly on the axle, and short carrying roller roll body can the bending distortion;

(2) lack the problem that there is not concentricity in carrying roller roll body in-to-in bearing arrangement, " not dead " phenomenon can not take place;

(3) even transmission course middle idler roller axle deforms, a plurality of short carrying roller that is connected on the roller carrier shaft also can remain in operation separately, and stuck phenomenon does not take place noninterference;

(4) owing to be difficult for the stuck phenomenon that deforms,, the present invention can reduce greatly so lacking the abrasion factor of carrying roller, long service life, and often maintain and replace is protected belt, and the work efficiency of whole conveyor device is improved;

(5) the present invention compares with the long carrying roller of traditional duplex bearing, and its requirement on machining accuracy is low, is easy to finish, and is low for equipment requirements, reduced the quantity of specialized equipment.

Below in conjunction with drawings and Examples the present invention is done and to describe explanation in detail.

Description of drawings

The structural representation of Fig. 1-existing carrying roller;

A kind of structural representation of Fig. 2-carrying roller roll body of the present invention;

The another kind of structural representation of Fig. 3-carrying roller roll body of the present invention;

Fig. 4-structural representation of the present invention (running condition reference diagram).

The explanation of accompanying drawing drawing:

1 carrying roller roll body, 2 roller carrier shafts, 3 bearing seats, 4 bearings, 5 circlips, 6 sealing members.

The specific embodiment

Referring to Fig. 2, carrying roller roll body of the present invention 1 is shorter, generally get final product at 5-20cm, carrying roller roll body 1 internal fixation is provided with bearing seat 3, and bearing seat 3 is an interference fit with carrying roller roll body 1, also can be made for one, on bearing seat 3, be provided with bearing 4, bearing 4 is abutted against with roller carrier shaft 2, utilizes circlip 5 that bearing 4 is fixing, and carrying roller roll body 1 two ends are provided with sealing member 6.

Shown in Figure 3 is the another kind of structure of carrying roller roll body 1 of the present invention, two adjacent very near bearings 4 can be set on the bearing seat 3 of T shape, because two bearings are mounted on the same bearing seat, distance is very near again, therefore can be considered as is a cover bearing, does not have the problem of concentricity.This kind structure is compared Fig. 2 structure, and its stability is higher.

Several short carrying roller roll bodies are connected on the roller carrier shaft, as shown in Figure 4, have just constituted sectional type carrying roller of the present invention.

Claims

1. sectional type carrying roller, have carrying roller roll body (1) and roller carrier shaft (2), it is characterized in that, carrying roller roll body (1) is the short roller body, be provided with bearing seat (3) in the short roller body, bearing seat (3) is provided with bearing (4) and is abutted against with roller carrier shaft (2), and N carrying roller roll body (1) is connected on the roller carrier shaft (2), and N is greater than 1.

2. sectional type carrying roller according to claim 1 is characterized in that bearing seat (3) is provided with a bearing (4).
