Description

[Detailed explanation of the idea] This invention relates to a power load testing device.

This system brakes a rotary member that is connected to the output shaft of the machine under test, such as an engine or motor, and uses a detector to detect the load that occurs due to the braking. The tube is expanded and braked by fluid (air, liquid) that is press-fitted using the tube.

Embodiments of this invention will be described below with reference to the accompanying drawings.

In the figure, A is a load testing device according to this invention, and this load testing device A consists of a rotating body 2 that rotates together with an input shaft 1, a drum 3 fitted around the outer periphery of this rotating body 2, and a drum 3 that is fitted around the outer circumference of this rotating body 2. A detector 5 such as a load cell is interposed between the rotating body 2 and the drum 3, and a tube 7 having a lining material 6 is interposed between the rotating body 2 and the drum 3, and a fluid is pressurized into the tube 7. It is composed of a pipe 8 provided as shown in FIG.

When the tube 7 is supported on the inner periphery of the drum 3, a hollow chamber 9 is provided within the periphery of the rotating body 2, and this hollow chamber 9
A cooling water inflow pipe 10 and a cooling water discharge pipe 11 are connected to one end side of the cooling water via a rotary seal 12.

In addition, when a tube 7 is supported on the outer periphery of the rotating body 2, a pipe 8 (not shown) is connected to the tube 7 via a rotary seal, and a hollow chamber 9 is connected to the outer periphery of the drum 3.
A pipe for inflowing the cooling water into the hollow chamber 9 and a pipe for discharging the cooling water (not shown) are connected to each other.

Note that the detector 5 supported by the fixing member 4 via a bracket 13 and the drum 3 were connected via a rod 14.

The tester according to this invention has the above-mentioned configuration, and in order to conduct a load test, the output shaft of the machine under test, such as an engine or a motor, is connected to the input shaft 1, and as the test machine operates, the input shaft is connected to the input shaft 1. Drive axis 1.

To brake the input shaft 1, air or liquid is injected from the pipe 8 into the tube 7 to expand the tube 7, thereby bringing the lining material 6 into pressure contact with the rotating body 2 and braking the input shaft 1.

At this time, a load is applied to the drum 3, and the load can be detected by the detector 5.

In addition, the tube applies pressure all around the area for braking, so
A uniform force is applied to the cutting edge, allowing for good braking.

Note that no bearings are required to support the drum, and the drum can be made compact.
