Embodiment
[0097] Such as Figure 3 ~ Figure 7 As shown, the intermediate bearing 100 of the present invention (such as Figure 5 shown) includes: hydraulic cylinder assembly, floor assembly, several sets of stud bolts 12, nuts 12.1, etc. for connecting the hydraulic assembly and the floor assembly, among which,
[0098] The hydraulic cylinder block assembly includes: pressure gauge 1, cylinder block 2, quick-connect hydraulic joint 3 (the hydraulic joint is commercially available), sealing ring 4, plunger 5, cylinder head 6, for fixing the cylinder head 6 A number of hexagon socket screws 6.3. Through the hydraulic cylinder assembly, a closed hydraulic space can be formed in the cylinder 2, so that when the hydraulic oil is injected, a thrust is generated on the plunger, and the working area of the plunger is, for example, 20cm 2 , the load value of the intermediate bearing can be obtained very intuitively according to the pressure value displayed by the pressure gauge (see the foll...

The invention discloses a hydraulic force-measuring device, a hydraulic force-measuring system and a measuring method of an intermediate bearing, wherein the hydraulic force-measuring device comprises a hydraulic cylinder component and a bottom plate component; the hydraulic cylinder component is used for forming an airtight hydraulic chamber and displaying a pressure value in the hydraulic chamber at the same time; the bottom plate component is used for butting the hydraulic cylinder component against the panel of an intermediate bearing seat by means of penetrating through a bolt hole of the bottom plate of the intermediate bearing seat; the hydraulic cylinder component is connected with the bottom plate component in a reeving manner through a plurality of groups of studs and nuts. The hydraulic force-measuring device, the hydraulic force-measuring system and the measuring method of the intermediate bearing are used cooperatively with a general hydraulic manual oil pump, so that the load of the intermediate bearing in a marine shafting can be measured actually. The hydraulic force-measuring device, the hydraulic force-measuring system and the measuring method of the intermediate bearing have the advantages that on one hand, the structure is simple and reliable, and the operation is convenient; on the other hand, the enterprise equipment investment can also be reduced, and the working efficiency is improved.
Description
technical field [0001] The invention relates to a hydraulic force measuring device, a system and a measuring method that can be used for measuring the load of a ship's intermediate bearing. Background technique [0002] Modern ship shafting consists of intermediate bearings, stern bearings, thrust shafts (generally set in the main engine), intermediate shafts, stern shafts and propellers, etc. The intermediate bearings and stern bearings are set at the tail of the ship's engine room. The intermediate shaft is installed on the intermediate bearing, the stern shaft is installed on the stern bearing, the front end of the intermediate shaft is connected to the output end of the main engine of the ship, the rear end is connected to the stern shaft (or other intermediate shafts, for long shaft systems), and the propeller is installed on the rear of the stern shaft . In this way, the power output by the main engine is transmitted to the propeller through the shaft system to rotate...
