Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a gear impact fatigue detection device. Background Art

[0002] There are many types of gears with different uses. In the actual production and application process, the failure forms of gears are also various. Gear failure generally occurs on the tooth surface and rarely occurs in other parts. According to the reasons for the failure of the gears at work, the common failure forms of gears can be analyzed as gear tooth breakage, tooth surface bonding, tooth surface fatigue pitting, tooth surface wear, plastic deformation, etc. In order to ensure the qualified rate of gears, gear impact fatigue detection devices are often used to detect gears.

[0003] An existing gear impact fatigue detection device (Announcement No.: CN117848643B) has at least the following disadvantages:

[0004] When the above patent is in use, the first driving device drives the gear to rotate, and the gear squeezes the impact part to shrink it, and at the same time the impact part rotates a certain angle around the first direction. As the gear continues to rotate, the gear loses its squeezing force on the impact part, and the impact part rotates around the second direction. At the same time, the impact part stretches to impact the tooth surface of the gear to detect the impact fatigue strength of the gear. Since the tooth shape of the involute gear is an involute type, the thickness of the tooth is different from the tooth top to the tooth root. The above patent can only perform impact testing on a fixed position on the gear tooth, and cannot comprehensively detect the impact resistance data of different positions of the tooth, which greatly reduces the reliability of the detection data.

[0036] In this embodiment, a second limiting sleeve 11 is fixedly installed on the upper surface of the testing platform 1, and a second square sliding column 12 is slidably installed on the inner wall of the second limiting sleeve 11. An airtight detection head 13 is fixedly installed on one end of the second square sliding column 12 close to the gear body 3, and a pressure gauge 14 is fixedly installed on the upper surface of the airtight detection head 13. The pressure gauge 14 is connected to the inside of the airtight detection head 13, and the airtight detection head 13 is abutted against the outer surface between two adjacent teeth of the gear body 3. An air pipe joint 18 is fixedly installed on the upper surface of the second square sliding column 12 close to the other end, and a flow channel is opened inside the second square sliding column 12.

There is a second turntable 15, the upper surface of the second turntable 15 is provided with a second cam groove 16, the lower surface of the second square slide column 12 near one end of the second turntable 15 is fixedly installed with a second guide column 17, the second guide column 17 is slidably installed with the inner wall of the second cam groove 16, the bottom end of the mounting shaft 2 passes through the lower surface of the detection platform 1 and is fixedly installed with a driven groove wheel 34, the lower surface of the detection platform 1 is rotatably installed with a first gear 36, the lower surface of the first gear 36 is fixedly installed with an active dial 35, the active dial 35 is meshed with the driven groove wheel 34, the bottom end of the second turntable 15 passes through the lower surface of the detection platform 1 and is fixedly installed with a first pulley 31, the lower surface of the rotation center of the active dial 35 is fixedly installed with a second pulley 3 2. The outer surfaces of the first pulley 31 and the second pulley 32 are sleeved with a first belt 33, which drives the second pulley 32 to rotate through the rotation of the active dial 35.

When the gear body 3 stops rotating, the airtight detection head 13 will move between two adjacent teeth of the gear body 3 and be flush with its surface. The airtight detection head 13 is connected to the external high pressure through the air pipe joint 18. The pump is connected to the airtight detection head 13 to spray high-pressure gas between two adjacent teeth. If the teeth are not deformed by the impact, the pressure gauge 14 on the upper surface of the airtight detection head 13 will display a normal air pressure value. If the teeth are deformed after the impact, a gap will be generated between the airtight detection head 13, thereby causing the gas inside the airtight detection head 13 to leak. The more serious the deformation of the teeth, the larger the gap between the teeth and the airtight detection head 13, the faster the gas leaks, and the lower the air pressure value displayed on the pressure gauge 14. The device can detect the degree of impact deformation of the teeth of the gear body 3 and combine it with the number of impacts to quickly detect the impact fatigue data of the gear body 3, which is convenient for detection personnel to use.

[0038] The first gear 36 drives the third pulley 38 to rotate through the second gear 37, and the third pulley 38 drives the fourth pulley 39 to rotate through the second belt 40, so that the fourth pulley 39 drives the spiral cam 25 to rotate. When the spiral cam 25 rotates, it drives the push-pull rod 26 to move away from the gear body 3 through the driving column 27, so that the push-pull rod 26 drives the impact block 22 to move away from the gear body 3. When the driving column 27 moves to the farthest point, it will be suddenly released under the action of the spring 28, and then the impact block 22 will impact the outer surface of the tooth at the corresponding position of the gear body 3.

[0040] It should be noted that when the present invention is in use, the inspector sleeves the gear body 3 to be inspected on the end of the mounting shaft 2 so that the keyway on the inner wall is aligned with the key on the outer surface of the mounting shaft 2, and then tightens the hexagonal clamping bolt 4 to firmly clamp the gear body 3; manually pushes the arc T-shaped slider 20 to slide along the inner wall of the T-shaped arc slide groove 19, so that the rotating sleeve 21 drives the impact block 22 to adjust the impact position, and the position of the impact block 22 is limited by inserting the pin 23 into the inside of the socket 24, and the driving motor 30 drives the active dial 35 to rotate, and the active dial 35 drives the first gear 36 to rotate, and the first gear 36 drives the third pulley through the second gear 37 38 rotates, the third pulley 38 drives the fourth pulley 39 to rotate through the second belt 40, so that the fourth pulley 39 drives the spiral cam 25 to rotate, and when the spiral cam 25 rotates, it drives the push-pull rod 26 to move away from the gear body 3 through the driving column 27, so that the push-pull rod 26 drives the impact block 22 to move away from the gear body 3.

[0041] At the same time, the rotation of the active dial 35 drives the driven groove wheel 34 to rotate intermittently, so that the driven groove wheel 34 drives the gear body 3 to rotate intermittently by an angle, which is convenient for impact detection of different teeth; the fifth pulley 41 is driven to rotate by the active dial 35, the fifth pulley 41 drives the sixth pulley 43 to rotate through the third belt 42, the sixth pulley 43 drives the first rotating disk 8 to rotate, the first rotating disk 8 drives the first square slide column 7 to slide intermittently reciprocatingly through the first cam groove 9 and the first guide column 10, when the gear body 3 stops rotating, the first square slide column 7 drives the positioning column to be inserted into the interior of the positioning hole 5, and the position of the gear body 3 is firmly locked by this device to prevent the position of the gear body 3 from moving during impact and affecting the detection result;

[0042] The second pulley 32 is driven to rotate by the rotation of the active dial 35, and the second pulley 32 drives the first pulley 31 to rotate through the first belt 33, so that the first pulley 31 drives the second turntable 15 to rotate, and the second turntable 15 drives the second square slide post 12 to slide intermittently back and forth through the second cam groove 16 and the second guide column 17, and the second square slide post 12 drives the airtight detection head 13 to move intermittently close to and away from the gear body 3. When the gear body 3 stops rotating, the airtight detection head 13 will move between two adjacent teeth of the gear body 3 and be flush with its surface. The airtight detection head 13 is connected to the external high-pressure pump through the air pipe joint 18. High-pressure gas is sprayed between two adjacent teeth. If the teeth are not deformed by the impact, the barometer 14 on the upper surface of the airtight detection head 13 will display a normal air pressure value. If the teeth are deformed after the impact, a gap will be generated between the airtight detection head 13, thereby causing the gas inside the airtight detection head 13 to leak. The more serious the deformation of the teeth, the larger the gap between the teeth and the airtight detection head 13, the faster the gas leaks, and the lower the air pressure value displayed on the barometer 14. By using this device to detect the degree of impact deformation of the teeth of the gear body 3 and combining it with the number of impacts, the impact fatigue data of the gear body 3 can be quickly detected, which is convenient for detection personnel to use.
