Abstract

The utility model discloses a middle suspension bearing for a helical conveyer, which comprises a middle suspension bearing, a bearing, a bearing base and a pressure plate. The bearing is mounted on the middle suspension bearing and arranged in the bearing base; and the pressure plate is arranged at two ends of the bearing base. The middle suspension bearing is characterized in that the bearing adopts a NK needle bearing; and a packing set is arranged in the bearing base and positioned between the bearing and the pressure plate. Due to the adoption of the NK needle bearing; the external dimension of the middle suspension bearing is reduced and the plugging phenomenon is also reduced, so that the equipment performance is more stable and the service life of the middle suspension bearing is prolonged; and due to the additional arrangement of the packing set, the sealing performance of the hanging bearing is improved and the plugging probability is further reduced.

Description

Suspension bearing in the auger loader

Technical field

The utility model relates to a kind of middle suspension bearing, specifically is the middle suspension bearing in a kind of LS type conveyor screw.

Background technology

Conveyor screw is the main unit of industrial or agricultural all departments mechanization transportation work, and transport is reduced labor intensity, and increases work efficiency, and is of wide application, and LS type conveyor screw is the regeneration product of GX type conveyor screw.Conveyor screw is commonly called as auger, it is the wider a kind of load transfer device of purposes in mineral products, feed, grain and oil, the building industry, angular divisions from the convey materials sense of displacement, conveyor screw is divided into horizontal conveyor screw and high low type conveyor screw two major types, is mainly used in horizontal feed and vertical-lift to bulk materials such as various powderies, graininess and fritter shapes.

LS type conveyor screw is to utilize the spiral of rotation that the material that is transferred is carried out transportation work along passing in the fixing casing, head and tail bearing move to outside the housing, traditional middle suspension bearing adopts plain bearing, and plain bearing is not long-pending greatly, putty is serious, leak tightness is poor, adopt the bearing of traditional form, not only because of putty influences normal work, but also shortened the service life of equipment.

The utility model content

In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide suspension bearing in the auger loader of a kind of rational in infrastructure, good airproof performance, long service life.

To achieve these goals, the technical solution adopted in the utility model is: suspension bearing in the auger loader, include middle hanging axis, bearing, bearing seat, pressing plate, on the middle hanging axis bearing is housed, bearing is located in the bearing seat, pressing plate is located at the two ends of bearing seat, it is characterized in that: described bearing adopts NK type needle bearing.

Be provided with packing in the described bearing seat, described packing is between bearing and pressing plate.

The beneficial effects of the utility model: owing to adopted NK type needle bearing, reduced the oad of middle suspension bearing,, made equipment performance more stable, prolonged the service life of middle suspension bearing so reduced the putty phenomenon; Owing to set up packing, improved the leak tightness of middle suspension bearing greatly, further reduced the probability of putty.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

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

Fig. 2 be shown in Figure 1 along A-A to cutaway view.

Among the figure: 1, middle hanging axis; 2, bearing; 3, bearing seat; 4, pressing plate; 5, packing.

The specific embodiment

As shown in Figure 1 and Figure 2, suspension bearing in the auger loader, hanging axis 1, bearing 2, bearing seat 3, pressing plate 4 in including, on the middle hanging axis 1 bearing 2 is housed, bearing 2 is located in the bearing seat 3, and pressing plate 4 is located at the two ends of bearing seat 3, it is characterized in that: described bearing 2 adopts NK type needle bearing.

Be provided with packing 5 in the described bearing seat 3, described packing 5 is between bearing 2 and pressing plate 4.
