Description
Technical Field
The utility model relates to an inference measurement device, in particular to a ship shafting thrust measurement device.
Background
When the ship sails, the main engine drives the propeller to rotate to push the ship body to advance or retreat, the thrust exerted on the ship body by the propeller determines the sailing speed and the maneuverability of the ship, the propeller thrust is one of key technical indexes in ship design, the propeller thrust not only determines the sailing speed of the ship, but also is an important basis for selecting the power of the main engine and is a key characteristic for designing a propulsion system. However, the propeller thrust during the design of most of the current ships is determined according to simulation calculation, actual test data is lacked, and a larger host must be selected for ensuring the navigational speed during the design of the ships, so that resource waste is caused.
Disclosure of Invention
The utility model aims to provide a thrust bearing pad for thrust measurement, which is used for measuring the thrust of a propeller on a thrust bearing of a ship propulsion shafting.
The purpose of the utility model is realized as follows:
the utility model relates to a thrust bearing pad block for thrust measurement, which is characterized in that: the thrust sensor is installed in the bearing bush through the adjusting ring, a seal sleeve channel is arranged inside the bearing bush, the seal sleeve is installed in the seal sleeve channel inside the bearing bush, and the seal sleeve channel is communicated with the space where the thrust sensor is located.
The present invention may further comprise:
1. the thrust sensor is arranged in the bearing bush in a clearance way.
2. The sealing sleeve is arranged in the bearing bush in an interference manner.
3. The thrust sensor is a spoke type force sensor.
4. The surface of the thrust sensor is spherical, and the rigidity of the thrust sensor is consistent with that of the bearing bush.
5. The height of the adjusting ring is adjusted to enable the bearing bush to be consistent with the height of other bearing bushes without thrust sensors.
The utility model has the advantages that: the thrust sensor is arranged in the circular bearing bush in a clearance mode, the height of the thrust bearing pad is adjusted through the adjusting ring, the height of the thrust bearing pad is kept consistent with that of other thrust pads without the thrust sensor, the rigidity of the thrust sensor is consistent with that of the thrust bearing pad, and the accuracy of thrust measurement is guaranteed.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of the present invention.
Detailed Description
The utility model will now be described in more detail by way of example with reference to the accompanying drawings in which:
with reference to fig. 1-2, the thrust bearing pad for thrust measurement of the present invention is composed of a circular pad 1, an adjusting ring 2, a thrust sensor 3, and a sealing sleeve 4. The adjusting ring 2 and the thrust sensor 3 are arranged in the circular bearing bush 1 in a clearance mode during installation, and the sealing sleeve 4 is arranged in the circular bearing bush 1 in an interference mode. The thrust sensor is a spoke type force sensor, when a thrust bearing pad deforms under stress, the elastic material of the sensor deforms, and the resistance value of a strain gauge adhered to the elastic material changes. The change of the resistance value of the strain gauge can be converted into a change signal of the output voltage of the bridge, and the thrust value is displayed through an external thrust measurement display device.
The thrust sensor 3 is installed in the circular bearing bush, the thrust sensor is installed in the middle of the circular bearing bush in a clearance mode, the height of a thrust bearing pad is adjusted through the adjusting ring, the height of the thrust bearing pad is kept consistent with the height of other thrust pads without the thrust sensor, the surface of the thrust sensor is spherical, the rigidity of the thrust sensor is consistent with that of the thrust bearing pad, and the accuracy of thrust measurement is guaranteed.
The technical problem to be solved by the utility model is as follows: a thrust bearing pad for thrust measurement is developed, and propeller thrust is calculated by utilizing voltage model conversion sent by deformation of a thrust sensor in the thrust pad under pressure.
