Abstract

The invention provides an external assembly scheme of a main shaft bearing of a rotating large disc of a particle friction barrel washing machine, which is characterized in that a large shaft sleeve 2.2 in a figure 5 is removed, rolling bearings 5 in the large shaft sleeve 2.2 are arranged at two ends (the bearings are externally arranged) of a main shaft 1, as shown in figure 6, the main shaft 1 and the rotating large disc 2 are relatively fixed, and the main shaft 1 rotates along with the rotating large disc 2; the main shaft 1 is supported on the frame through a bearing 5 and a bearing box 6; because the rotating speed of the large rotating disc is very low, the plastic polymer bearing 7 is used for replacing the rolling bearing 5 and the bearing box 6, see fig. 7, so that the durability of the bearing is improved, and the cost is effectively reduced. The external assembly effectively solves the existing problems, and particularly provides great convenience for equipment maintenance and bearing replacement.

Description

External assembly scheme for main shaft bearing of rotary large disc of particle friction barrel washing machine

Technical Field

The invention relates to an assembly scheme of a rotating disk, a main shaft and a bearing of a friction barrel washing machine for drinking water packaging barrel particles, and belongs to parts of a cleaning device for drinking water packaging barrels.

Technical Field

The rotary large disc in the previously applied ZL 201120090337.8/ZL 201520528718.8/ZL 201521014694.0 is supported on the main shaft (formerly 'large shaft') by bearings in a large sleeve; (note: ZL 201520528718.8 is a one-layer barrel washing machine, and the scheme 1 and the figure 2 are two-layer barrel washing machines), and the assembly structure of a rotary large disc (rotary drum) 2, a large shaft sleeve 2.2, a rolling bearing 5 and a main shaft 1 can be seen through figures 1 to 5; because the bearing is installed in the large shaft sleeve, the assembly mode is called as 'bearing built-in assembly', and the built-in assembly is characterized in that: the main shaft 1 is fixed on the frame through a shaft clamp and is fixed without rotation, and the rotating large disc is supported for rotation through a bearing in a large shaft sleeve on the large disc; the large disc rotating support mode has the problems of complex structure, high manufacturing cost, difficult maintenance and the like, and particularly when a bearing needs to be replaced, the whole rotating large disc and the main shaft need to be dismounted together, so that the large disc rotating support mode is very troublesome, time-consuming, labor-consuming and production-influenced;

disclosure of Invention

In order to solve the above problems, the present invention proposes a solution; an assembly scheme of a rotating large-disc main shaft bearing external type of a particle friction barrel washing machine is characterized in that a large shaft sleeve 2.2 in a figure 5 is removed, rolling bearings 5 in the large shaft sleeve 2.2 are arranged at two ends (the bearings are external) of a main shaft 1, as shown in a figure 6, the main shaft 1 and the rotating large disc 2 are relatively fixed, and the main shaft 1 rotates along with the rotating large disc 2; the main shaft 1 is supported on the frame through a rolling bearing 5 and a bearing box 6; because the rotating speed of the large rotating disc is very low, the plastic polymer bearing 7 is used for replacing the common rolling bearing 5 and the bearing box 6, see fig. 7, so that the durability of the bearing is improved, and the cost is effectively reduced. The external assembly effectively solves the existing problems, and particularly provides great convenience for equipment maintenance and bearing replacement.

Detailed Description

Fig. 1 is a front view of the appearance of a particle friction washing machine, and fig. 2 is a back view of the appearance of a particle friction washing machine, and the positions of a main shaft 1, a rotating large disk 2 and the like in the whole machine can be seen.

The conventional installation mode of parts such as the main shaft 1, the large rotating disc 2, the rolling bearing 5 and the like is called 'bearing built-in assembly'; for convenience, the unnecessary parts in fig. 1 and fig. 2 are hidden to obtain fig. 3, the rotary large disc 2 in fig. 3 is cut away to obtain fig. 4, and I in fig. 4 is partially enlarged to obtain fig. 5; therefore, the large rotating disc 2 is fixedly connected with the shaft sleeve 2.2, the rolling bearing 5 is arranged in the shaft sleeve 2.2, the rolling bearing 5 is arranged on the main shaft 1, the main shaft 1 is fixed on the frame 3 through the shaft clamp 4, and the installation mode is characterized in that the main shaft 1 is fixed and does not rotate along with the large rotating disc 2.

As shown in FIG. 6, the large shaft sleeve 2.2 in FIG. 5 is removed, and the large rotating disc 2 is directly fixed on the main shaft 1; the rolling bearings 5 in the large shaft sleeve 2.2 are moved outwards to two ends of the main shaft 1, the rolling bearings 5 are arranged in a bearing box 6, and the bearing box is arranged on the frame 3.

Referring to FIG. 7: the plastic polymer bearing 7 in fig. 7 is used to replace the rolling bearing 5 and the box bearing box 6 in fig. 6.

Referring to FIG. 7: the plain bearing 7 in fig. 7 is used instead of the rolling bearing 5 and the cartridge bearing cartridge 6 in fig. 6.

The invention is characterized in that: the main shaft 1 and the large rotating disc 2 are assembled into a relatively fixed whole and rotate at the same time; the rolling bearings 5 are arranged at two ends of the main shaft 1; a plastic high-molecular bearing 7 is used for replacing a common rolling bearing 5 and a bearing box 6; this type of assembly is called a "bearing external assembly".
