Abstract
The utility model relates to a supporting device of a helical conveyer connection shaft, which substitutes a suspension bearing in a helical conveyer to have the same supporting function, and comprises carrier rollers, compression rollers, an eyelet bolt, a supporting plate, a bracket and relevant accessories, wherein an inner hole of a cylindrical helical spring on the carrier rollers is in clearance fit with a pin shaft, and an outer circle is contacted with a connection shaft in a rolling way. The carrier rollers are arranged on the circumference which adopts the axis of the connection shaft as the center and are symmetrically arranged on the lower side surface of the connection shaft. The elastic vibration which is generated when the cylindrical helical spring on the carrier roller iscontacted with the connection shaft in a rolling way can buffer and absorb the shock so as to improve the stress state, so that the material is free from being adhered onto the shaft, and the servicelife can be prolonged. In addition, the supporting device also has the advantages of high-temperature resistance, no lubrication, automatic centering, simple and convenient maintenance and the like.
Description
Technical field
The utility model relates to a kind of bearing set of conveyor screw adapter shaft.
Background technology
When conveyor screw convey materials distance surpasses 3 meters, produce bending phenomenon in order to prevent screw shaft, every a segment distance suspension bearing will be set, general suspension bearing is arranged on and is used to connect two sections spirochetal adapter shafts.The prior art suspension bearing adopts antifriction-bearing box or bearing shell, is difficult to guarantee owing to seal and lubricate, and causes service life short, influences normal operation, the maintenance cost height.
Summary of the invention
The purpose of this utility model provides a kind of same bearing set that can finish the conveyor screw adapter shaft of supporting functions, is used to replace above-mentioned suspension bearing.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of bearing set of conveyor screw adapter shaft, comprise carrying roller, pressure roller, eyelet bolt, back plate, support and corresponding auxiliary, cylindrically coiled spring endoporus on the described carrying roller and bearing pin are free-running fit, and outer ring and adapter shaft are rolling touch.
It is on the circumference at center that described carrying roller is positioned at the adapter shaft axis, and is symmetrical set the downside in adapter shaft.
The axis normal of eyelet bolt screw rod is in the axis of bearing pin, and the spherical washer that the upper end screw rod passes on the back plate in proper order is connected with nut thread, and lower end circle open-work is captiveed joint with the bearing pin that is positioned at a top of the trellis.
The beneficial effects of the utility model are, because carrying roller is by cylindrically coiled spring and adapter shaft rolling touch, the elasticity of generation is trembleed can buffer shock-absorbing, improves strained condition, and material can not stick on the axle, will prolong its service life.High temperature resistant in addition in addition, need not lubricate, automatic aligning, and simple and convenient for maintenance.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
1. eyelet bolts among the figure, 2. nut, 3. spherical washer, 4. spherical washer, 5. back plate, 6. spring cotter, 7. flat gasket, 8. bearing pin, 9. roller, 10. support, 11. bearing pins, 12. cylindrically coiled springs, 13. adapter shafts.
The specific embodiment
Fig. 1, Figure 2 shows that the preferred embodiment of the bearing set of the utility model conveyor screw adapter shaft.In order to realize supporting adapter shaft 13, and then support the function of whole helicallobe, be provided with two carrying rollers and a pressure roller on the circumference that with adapter shaft 13 axis is the center, carrying roller is symmetrical set the downside at adapter shaft 13, and pressure roller is positioned at the upper end of adapter shaft 13.Be with cylindrically coiled spring 12 on the bearing pin 11 that described carrying roller is with support 10 links to each other, and rotatable, and outer ring and adapter shaft 13 form rolling touch.Because cylindrically coiled spring 12 is a friction of rolling with contacting of adapter shaft 13, and can produce the elasticity vibration in the motion contact, can effectively reduce the wearing and tearing between them, buffer shock-absorbing improves strained condition, and the powdery caking materials can not adhere on the axle.Described pressure roller is positioned at the upper end of adapter shaft 13, bearing pin 8 is fixed on the support 10 by spring cotter 6, flat gasket 7, roller 9 endoporus and bearing pin 8 are free-running fit, can rotate, cylindrical and adapter shaft 13 form rolling touch, and the effect of pressure roller is to prevent the incidental upwards jumping phenomena of screw shaft in running condition.Also be fixed with eyelet bolt 1 on the bearing pin 8, screw axis is perpendicular to the axis of bearing pin 8, and the upper end screw rod passes spherical washer 3, the spherical washer 4 on the back plate 5 in proper order, is threaded with nut 2, and lower end circle open-work is captiveed joint with the bearing pin 8 that is positioned at support 10 tops.And back plate 5 crosswise fixed are in the both sides of conveyor screw hopper.Spherical washer 3, spherical washer 4 are set on back plate 5, can realize the function of aligning.
