Description

Technical Field

[0001] This utility model relates to the field of sensor testing technology, specifically to a bearing impact pulse sensor sealing assembly and a pulse sensor having the assembly. Background Technology

[0002] Impact pulse sensors are widely used in testing for faults such as wear and lack of lubrication in rolling bearings. However, impact pulse sensors themselves are not waterproof or oil-proof. In large machinery bearings where there is oil or water pressure on the outer ring, the front end of the sensor needs to be immersed in lubricating oil, and the rear end of the sensor will be exposed to water, making direct installation for testing impossible. Therefore, it is necessary to design an installation sealing component for impact pulse sensors suitable for such testing environments to protect the impact pulse sensors. Summary of the Invention

[0003] To address the aforementioned problems, this utility model proposes a bearing impact pulse sensor sealing assembly and a pulse sensor incorporating the assembly, which can internally assemble the impact pulse sensor to achieve waterproof and oil-proof immersion effects.

[0004] The above objectives are achieved through the following technical solutions:

[0005] This utility model first provides a bearing impact pulse sensor sealing assembly, including a sensor mounting base. The upper part of the sensor mounting base has an embedded O-ring seal, and the bottom has a protrusion for contacting the bearing surface. A threaded hole in the center of the sensor mounting base is used to fit and fix the impact pulse sensor thereto. Through holes around the sensor mounting base are connected to the bottom of the main assembly by fixing bolts. The main assembly is hollow inside to house the impact pulse sensor. Two grooves are provided on the outer wall of the middle section of the main assembly, and two O-ring seals are placed in the grooves. The lower outer wall of the main assembly is smooth, and a through hole in the inner wall of a welded flange passes through the main assembly. The welded flange and the main assembly are sealed by the two O-ring seals.

[0006] Furthermore, a connecting and fixing device is provided above the welding flange. The connecting and fixing device is fitted onto the upper section of the main body component and is connected to the main body component by threads. A locking nut is provided above the connecting and fixing device. The locking nut is fitted onto the upper section of the main body component by threads. The fixing device is fixed to the welding flange by fixing screws.

[0007] Furthermore, a waterproof connector is provided at the top of the main component for the cable of the impact pulse sensor to pass through.

[0008] Furthermore, a mounting baffle is provided on the lower periphery of the main component, and the top of the mounting baffle is welded to the bottom of the welding flange.

[0009] This utility model also provides a pulse sensor having the above-mentioned bearing impact pulse sensor sealing assembly.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The sealing component of this utility model fully considers the impact pulse sensor's protection from moisture, corrosion, or impact damage under the influence of factors such as the humid environment where the impact pulse sensor is located, the impact pulse sensor passing through the lubricating oil layer, and the collision of foreign objects around the impact pulse sensor during actual use. It extends the service life of the impact pulse sensor and prevents lubricating oil from leaking from the mounting hole.

[0012] 2. The protruding design at the front end of the sensor mounting base ensures that the sealing assembly is not affected by the curved surface of the bearing, and can effectively transmit the bearing vibration and impact signal to the internal impact pulse sensor. Attached Figure Description

The upper part of the sensor mounting base 1 is inlaid with an O-ring seal 3, and the bottom has a protrusion 15 for contacting the bearing surface. The protrusion 15 is used to contact the bearing surface and transmit vibration to the internal sensor. The center threaded hole of the sensor mounting base 1 is used to fit and fix the impact pulse sensor 4 to it. The four through holes of the sensor mounting base 1 are connected to the bottom of the main body assembly 8 by fixing bolts 2. The impact sensor 4 is placed in the sensor mounting base 1 with the O-ring seal 3 and is bolted to the main body assembly 8 to achieve a front-end sealing effect.

The outer wall of the middle section of the main body component 8 is provided with two grooves, and an O-ring seal 5 is provided in the grooves. The lower section of the main body component 8 has a smooth outer wall. The through hole in the inner wall of the welding flange 6 passes through the main body component 8 and the main body component 8. The welding flange 6 and the main body component 8 are sealed by the O-ring seal 5 to prevent solution leakage.

[0025] A connecting and fixing device 7 is also provided above the welding flange 6. The connecting and fixing device 7 is fitted onto the upper section of the main body component 8 and is threadedly connected to the main body component 8. A locking nut 10 is provided above the connecting and fixing device 7, and the locking nut 10 is threadedly fitted onto the upper section of the main body component 8. The fixing device 7 and the welding flange 6 are fixed by fixing screws 11. A waterproof connector 9 is provided at the top of the main body component 8 for the cable of the impact pulse sensor 4 to pass through. A mounting baffle 12 is provided on the lower periphery of the main body component 8. The top of the mounting baffle 12 is welded to the bottom of the welding flange 6. During the installation of the welding flange 6, a ring is first welded around the connection with the mounting baffle 12, and the main body component 8 passes through the middle through the internal through hole and is connected and fixed by the connecting and fixing device 7.

After adjustment, the upper end is locked and fixed with a lock nut. The assembly achieves a sealing effect through an O-ring. After pressure resistance test, it can withstand 1.5MPa pressure without leakage.
