Description

Spiral hanging bearing of shot blasting machine

Technical Field

The utility model relates to a shot-blasting machine production field, in particular to bearing is hung to shot-blasting machine spiral.

Background

The spiral is the main equipment for conveying shot materials of the shot blasting machine, the length of one spiral is usually different from 5 to 8 meters, and a hanging bearing is arranged in the middle of one spiral in normal use. Because the hanging bearing is immersed in the pill material for a long time, the working environment is severe, and the service life is short. Meanwhile, the cost of the existing hanging bearing is about 3.5 ten thousand yuan per unit of the famous coin, and the production cost is greatly increased.

In the prior art, as shown in fig. 1, a spiral is divided into two sections and driven by two motors at the same time. The two sections of the spiral are connected by a hanging coupler, the hanging piece is divided into three parts, two ends are half couplers 101 with rubber poured inside, and a hanging bearing 102 is arranged in the middle. The two half-couplings 101 are arranged on the same pin shaft 103, and the middle part of the two half-couplings is provided with an adjustable bearing seat 102 which can bear larger radial and axial loads during operation. The two half-couplings 101 are connected by a pin shaft 103, six reinforcing ribs are uniformly distributed in the half-couplings 101, and rubber is poured in the connection mode. The rubber is thus integrated with the coupling part 101 housing and the intermediate core. The rubber is poured inside the half coupling originally to solve the problem that the two spirals are slightly different in coaxiality, and the rubber has good shock resistance and shock absorption functions, so that the instability and the jumping of the spirals in the working process can be relieved. However, the middle rubber often breaks in actual production, which causes the whole hanging to fail. The comprehensive analysis mainly comprises the following reasons: (1) and because the two driving motors are synchronous motors, errors can be generated along with the increase of the use frequency. The starting error of the driving motor can cause a larger torsion effect on the hanger. So that a gap can be formed between the rib and the rubber on the coupler iron core, and finally the rubber is twisted off.

(2) In order to obtain high strength when pouring rubber, a vulcanization treatment is generally adopted. Although the strength of the rubber is increased, the hardness of the rubber is increased, and the elasticity and toughness are reduced. When the shot blasting machine starts and stops, the ribs on the iron core have larger torsional force action on rubber, and the elastic convolution allowance is very small.

(3) When the screw works, high temperature is generated between the screw and the pellets due to friction and is transmitted to two ends of the hanging bearing through the screw shaft. Because the installation position of the hanging bearing and the design of the oil filling nozzle cause that the bearing lubrication and maintenance can not be in place, the bearing is easily worn under the high-temperature environment for a long time, and the coaxiality of the screw has larger error until the bearing is damaged.

Therefore, a novel spiral hanging bearing of the shot blasting machine is needed.
