Problems solved by technology

Of course, if the diameter of the main shaft is increased to form an air passage with a large cross-sectional area, the supply time and discharge time of air can be shortened, but in this case, with the increase in the diameter of the main shaft, various components such as bearings related to the main shaft It also becomes large, which is one of the causes of the overall size and weight of the device

Embodiment approach ）

[0084] The present invention can also be implemented in the following manner.

[0085] (1) In the above embodiment, the tire W is supplied with pressurized air from the lower rim side and the upper rim side, and the air filled in the tire W is discharged. However, it is also possible to supply the pressurized air only from the lower rim side. The air is supplied and discharged from the tire W from the lower rim side and the upper rim side. Thereby, it is possible to shorten the discharge time compared with the conventional technology in which supply and discharge are performed only from the lower rim side.

[0086] (2) Alternatively, it may be implemented in such a manner that the pressurized air is supplied from the lower rim side and the upper rim side, and the air from the tire W is discharged only from the lower rim side. Accordingly, it is possible to shorten the pressurized air supply time compared with the conventional technique in which the pressurized air is supplied...

Abstract

The present invention is provided with first and second ventilation channels capable of feeding air into a tire sandwiched by an upper rim and a lower rim and capable of discharging air in the tire. A part of each of the ventilation channels comprises a ventilation hole drilled in a spindle and a ventilation hole drilled in a connection shaft.

Description

technical field [0001] The present invention relates to a tire inspection device for inspecting dynamic balance, uniformity, etc. of tires. Background technique [0002] In a tire inspection device, for example, a dynamic balancer for tires that inspects the dynamic balance of tires, the dynamic balance of tires is inspected as follows. That is, the tire to be inspected is clamped between the upper rim that is raised and lowered and the lower rim that is connected and fixed to the main shaft. In this state, air is supplied into the tire to inflate it. After that, the drive spindle is rotated to rotate the tire at a specified speed. At this time, the centrifugal force in the horizontal direction generated by the imbalance of the tire is measured with a load cell such as a load cell. Air supply into the tire and air discharge after inspection are performed only on the lower rim side through an air passage formed inside the main shaft on the lower rim side (for example, refe...
