Problems solved by technology

[0005] In the work of the existing electric axis measuring device, due to the general design of two-point symmetry 180 0 The driving method of the pile structure, this structure has a point of contact that often occurs in the transmission, resulting in unreliable driving and poor symmetry
If a single point of force occurs, the drive plate bolts that should only be subjected to axial force are forced to be subjected to tangential shear force, and the bolts are deformed and locked due to this.

Embodiment

[0055] The specific structure of each part of the vertical rotating machine spindle axis measuring device according to an embodiment of the present invention is as follows: Figure 4-10 As shown, it includes: transmission disc 1, which is made of No. 45 forged steel or other materials of equal strength; key 2 is installed in the groove of clutch disc 4, and is an intermediate transitional transmission part for external drive device 2; clutch disc 4 is an accessory The bolts are placed between the clutch disc 4 and the shaft end to limit the axial force that the clutch disc 4 is subjected to, so that the clutch disc 4 is firmly fixed on the top of the measured large shaft shaft end.

[0056] The clutch disc 4 is made of forged steel with a thickness of 165mm, and there are five grooves on the upper circumference, and five transmission keys 5 are inserted in the grooves (such as figure 2 ), after this key is installed on the clutch disc 4, the external drive mechanism (usually ...

Abstract

The invention discloses a measuring device for the shaft axis of a vertical rotating machine, which comprises: a frame, the frame has a central hole of the frame; several driving devices installed on the frame, each driving device The output end has a driving gear; a driven gear, the driven gear is arranged in the center hole of the frame, and the driven gear meshes with each of the driving gears; the driven gear has a gear center hole; and a clutch disc, The clutch disc is arranged in the center hole of the gear for connecting with the measured main shaft; the clutch disc is keyed to the driven gear. The structure adopts multi-point transmission, which has little influence on the axis measuring device, can continue to work safely and reliably, and improves the operation reliability of the electric axis measuring device.

Description

technical field [0001] The invention belongs to the technical field of auxiliary detection instruments for vertical rotating machines, and relates to a measuring device for the shaft axis of a vertical rotating machine. Background technique [0002] In hydropower plants and other industries, axis measurement requires frequent operations during unit installation and maintenance. Traditionally, there are methods such as manpower axis measurement, crane traction, electric axis measurement device, etc. Electric axis measurement is the mainstream direction of development in recent years. This method has many advantages such as reliable transmission, convenient installation, accurate stop point, and stable speed. [0003] The main shaft of large-scale vertical rotating machinery is generally manufactured in sections. Before and after the installation or maintenance of the equipment, especially the large and medium-sized vertical hydroelectric units, it is necessary to carry out r...
