Abstract

The utility model relates to a vertical spiral tail end connection structure which comprises a spiral blade shaft arranged on a spiral outer tube, a tail shaft, an end plate and a bearing carrier, wherein the spiral blade shaft is connected with one end of the tail shaft; the other end of the tail shaft penetrates through the end plate and extends into the bearing carrier; a bearing and packings are arranged in the bearing carrier; the tail shaft sequentially penetrates through the packings and are connected with a bearing inner race; the bearing carrier is connected with a bearing outer ring through a sealing cowling; and a sealing cover is connected between the packings in the bearing carrier and the tail shaft. The utility model pulls the sealing elements and the bearing away, thereby enhancing the sealing property and protecting the bearing; a small amount of leaking ash can drop off at the middle section, but can not reach to the inside of the bearing, thereby greatly prolonging the service life of the bearing; and the sealing elements can be replaced only by opening the sealing cover, so the utility model is more convenient to operate.

Description

Vertical spin machine tail end connection structure

Technical field

The utility model relates to a kind of vertical spin machine tail end connection structure.

Background technology

Original design packing element, bearing and the design of bearing seat one; Has certain fluidity and pressure in cement discharging spiral in service inside; Ash usually can appear leaking in packing element; Even if the little cement dust gets into outside framework oil seal and bearing, make bearing wear and tear soon and scrap that the life-span reduces greatly; The replacing of packing element, bearing is simultaneously wasted time and energy, and has reduced the start Occupation coefficient of equipment.

Summary of the invention

The purpose of the utility model is exactly the weak point in the background technology, and a kind of vertical spin machine tail end connection structure is provided.

For achieving the above object, the utility model adopts following technical scheme: vertical spin machine tail end connection structure comprises the spiral shell rachis, tailing axle, end plate and the bearing seat that place the spiral outer tube; The spiral shell rachis is connected with tailing axle one end; The tailing axle other end passes end plate and stretches in the bearing seat, is provided with bearing, packing in the bearing seat, and tailing axle passes packing successively and is connected with bearing inner ring; And bearing seat is connected with outside race through closing cap, is connected with seal cover cap between packing and the tailing axle in the bearing seat.

For a kind of optimization of the utility model, outside framework oil seal is connected between bearing seat inner seal cover lid and the tailing axle.

The utility model is compared with background technology, has packing element and position of bearings are drawn back, and has strengthened sealing property; Protected bearing; Also can drop even a spot of leakage ash occurs, can not arrive bearing inside, thereby increase the service life of bearing greatly at interlude; And packing element only need open seal cover cap and just can realize changing, and it is more convenient to operate.

Description of drawings

Fig. 1 is the scheme drawing of vertical spin machine tail end connection structure.

The specific embodiment

Embodiment 1: with reference to Fig. 1.Vertical spin machine tail end connection structure; Comprise the spiral shell rachis 1, tailing axle 3, end plate 4 and the bearing seat 5 that place spiral outer tube 2, spiral shell rachis 1 is connected with tailing axle 3 one ends, and tailing axle 3 other ends pass end plate 4 and stretch in the bearing seat 5; Be provided with bearing 7, packing 10 in the bearing seat 5; Tailing axle 3 passes packing 10 successively and is connected with bearing 7 inner rings, and bearing seat 5 is connected with bearing 7 outer rings through closing cap 6, is connected with seal cover cap 9 between bearing seat 5 interior packings 10 and the tailing axle 3.Outside framework oil seal 8 is connected between bearing seat 5 inner seal covers lid 6 and the tailing axle 3.

What need understand is: though present embodiment is to the utility model detailed explanation of contrasting; But these explanations; It is simple declaration to the utility model; Rather than to the restriction of the utility model, any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the utility model.
