Embodiment 1

[0020] Such as figure 1 Shown: It is a semi-unloading structure with double-sided support and lower support structure:

[0021] A motor shaft support structure for a plastic high-speed mixer, comprising a motor 1, a motor bottom plate 2, a motor shaft 3 and a motor pulley 4, the motor shaft 3 drives the motor pulley 4 to rotate, and the motor pulley 4 is connected to the mixer through a transmission belt 5 The pulley 6 is connected to the transmission, and a short shaft 13 is installed coaxially with the motor shaft 3 at the lower end of the motor pulley 4. One end of the short shaft 13 is installed on a support bearing 7, and the other end of the short shaft 13 passes through the shaft sleeve. 14 is connected with the motor pulley 4, the short shaft 13 is connected with the shaft sleeve 14 through a key connection, and the support bearing 7 is fixedly connected with the motor bottom plate 2 through a support seat 8.

[0022] It also includes a tensioning device 17, which is ...

Embodiment 2

[0025] Such as figure 2 Shown: fully unloaded structure with coupling:

[0026] A plastic high-speed mixer motor shaft support structure, comprising a mixer base 16, a motor 1, a motor bottom plate 2, a motor shaft 3 and a motor pulley 4, the motor shaft 3 drives the motor pulley 4 to rotate, and the motor pulley 4 passes through the transmission The belt 5 is connected to the pulley 6 of the mixer for transmission. At the axis of the motor pulley 4, a pulley shaft 15 that runs through the motor pulley 4 is installed. The pulley shaft 15 is installed at the upper and lower ends of the motor pulley 4. An upper support bearing 9 and a lower support bearing 10, the motor pulley 4 is fixed on the mixer base 16 through the pulley shaft 15 and two support bearings; also includes a coupling 11 and a coupling base 12, the coupling Both ends of the shaft coupler 11 are respectively connected to the motor shaft 3 and the pulley shaft 15 , and the shaft coupling base 12 is connected to...

Abstract

The invention discloses two motor shaft supporting structures with a simple both-side supporting structure. According to the first scheme, a half-unloading structure with both-side supporting and lower supporting structure following is adopted. According to the second scheme, a total-unloading structure with a coupler is adopted. The axial compression force borne by a motor shaft can be effectively shared and unloaded through the two motor shaft supporting structures, and therefore the motor shaft can be prevented from being damaged and pulled broken; the half-unloading supporting structure or the total-unloading supporting structure can be flexibly selected according to cost, the technology, the field installing environment and the like.

Description

technical field [0001] The invention belongs to the technical field of plastic processing equipment, and in particular relates to a motor shaft support structure of a plastic high-speed mixer. Background technique [0002] High-speed mixer is an indispensable key equipment in plastic processing industry, especially PVC plastic processing industry. In the current plastics processing industry, the volume of the mixer is required to be larger and larger, and the power of the driving motor is also required to be larger and larger. This will bring about a problem. When the driving motor is running, the pressure on the motor shaft The force and torque are very large, and the motor shaft is often broken. The existing motor shaft support structure mostly adopts one-sided cantilever support, which cannot effectively unload the load. Contents of the invention [0003] The purpose of the present invention is to provide a motor shaft support structure adopting a double-sided simply ...
