Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, specifically relating to an automatic filter speed reducer. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a driven machine. It plays a role in matching speeds and transmitting torque between the prime mover and the driven machine or actuator, and its applications are extremely widespread in modern machinery.

[0003] During the operation of existing speed reducers, the lubricating oil inside the housing will form sludge under the long-term high temperature. In addition, the internal gears will generate fine iron filings when they rub against each other. The sludge and iron filings mix together to produce impurities in the lubricating oil. The long-term accumulation of impurities will affect the normal operation of the speed reducer, accelerate the wear of parts, and easily cause damage to parts, resulting in a very high failure rate.

[0024] Example 1: An automatic filter reducer includes: a housing 1, on which a first rotating shaft 2, a second rotating shaft 3, and a third rotating shaft 4 are rotatably connected. A first pinion 5 is mounted on the first rotating shaft 2, a first large gear 6 meshing with the first pinion 5 is mounted on the second rotating shaft 3, a second pinion 7 is mounted on the second rotating shaft 3, and a second large gear 8 meshing with the second pinion 7 is mounted on the third rotating shaft 4. A self-cleaning mechanism 9 for filtering impurities in lubricating oil is mounted on the housing 1. In this application, the first rotating shaft 2, the second rotating shaft 3, and the third rotating shaft 4 are rotatably connected on the housing 1. A first pinion 5 is mounted on the first rotating shaft 2, a first large gear 6 meshing with the first pinion 5 is mounted on the second rotating shaft 3, a second pinion 7 is mounted on the second rotating shaft 3, and a second large gear 8 meshing with the second pinion 7 is mounted on the third rotating shaft 4. A self-cleaning mechanism 9 for filtering impurities in the lubricating oil is mounted on the housing 1. The self-cleaning mechanism 9 can circulate and filter the internal lubricating oil during normal operation of the reducer, thereby removing impurities mixed in the lubricating oil, ensuring the normal operation of the reducer, reducing wear on parts and preventing damage to parts, and thus reducing the failure rate.

[0025] Example 2: Based on Example 1, the self-cleaning mechanism 9 includes: a drive gear 91, a drive gear 91 mounted on the third rotating shaft 4, a transmission shaft 92 rotatably connected inside the housing 1, a transmission gear 93 meshing with the drive gear 91 mounted on the transmission shaft 92, a connecting pipe 94 mounted on the housing 1, both ends of the connecting pipe 94 communicating with the interior of the housing 1, an impeller 95 mounted on the transmission shaft 92, the impeller 95 placed inside the connecting pipe 94, and an impurity interception mechanism 96 mounted on the connecting pipe 94. In this application, the drive gear 91 is mounted on the third rotating shaft 4, and the transmission shaft 92 is rotatably connected inside the housing 1. The impeller 95 is located inside the connecting pipe 94. A transmission gear 93 is installed that meshes with the drive gear 91. A connecting pipe 94 is installed on the housing 1, with both ends of the connecting pipe 94 communicating with the interior of the housing 1. An impeller 95 is installed on the drive shaft 92 and is placed inside the connecting pipe 94. An impurity interception mechanism 96 is installed on the connecting pipe 94. When the reducer is operating normally, the impeller 95 can be driven by the internal transmission to continuously pump lubricating oil into the connecting pipe 94. The lubricating oil is filtered by the impurity interception mechanism 96 inside the connecting pipe 94, thereby removing impurities mixed in the lubricating oil, ensuring the normal operation of the reducer, reducing wear on parts and preventing damage to parts, and thus reducing the failure rate.

[0026] Example 3: Based on Example 2, the self-cleaning mechanism 9 further includes: a first valve 97 and a second valve 98 installed on the connecting pipe 94, and an impurity interception mechanism 96 placed between the first valve 97 and the second valve 98. In this application, by installing the first valve 97 and the second valve 98 on the connecting pipe 94 and placing the impurity interception mechanism 96 between the first valve 97 and the second valve 98, the operator can avoid lubricating oil leakage by closing the first valve 97 and the second valve 98 when cleaning the impurity interception mechanism 96, thereby improving the safety of use.

[0027] Example 4: Based on Example 3, the impurity interception mechanism 96 includes: a fixing ring 961, which is installed on the connecting pipe 94. The fixing ring 961 is positioned between the first valve 97 and the second valve 98. An interception ring 962 is slidably connected to the fixing ring 961, and a filter screen 963 is installed on the interception ring 962. This application improves the ease of use by installing a fixing ring 961 on the connecting pipe 94, positioning the fixing ring 961 between the first valve 97 and the second valve 98, slidably connecting the fixing ring 961 to the fixing ring 962, and installing a filter screen 963 on the interception ring 962, allowing the operator to directly remove the interception ring 962 for cleaning when too much impurity is collected on the filter screen 963.

[0028] Example 5: Based on Example 4, the impurity interception mechanism 96 further includes a sealing strip 964. A sealing strip 964 is provided between the fixing ring 961 and the interception ring 962. By providing a sealing strip 964 between the fixing ring 961 and the interception ring 962, this application improves the sealing efficiency, avoids lubricating oil leakage, and thus improves the safety of use.

[0029] Example 6: Based on Example 4, the impurity interception mechanism 96 further includes a push-pull handle 965. The push-pull handle 965 is installed on the interception ring 962. By installing the push-pull handle 965 on the interception ring 962, this application facilitates direct manual operation by the operator, thus improving the ease of use.

[0030] Example 7: Based on Example 4, the housing 1 is provided with an oil injection hole 10. In this application, by providing an oil injection hole 10 on the housing 1, lubricating oil can be directly injected into the reducer when there is a large shortage of oil inside, thereby improving working efficiency.

[0031] Example 8: Based on Example 4, a sealing bolt 11 is installed on the oil injection hole 10. This application avoids the leakage of lubricating oil by installing a sealing bolt 11 on the oil injection hole 10, thereby improving the safety of use.

[0032] Work process:

[0033] When the reducer is working, the external motor first drives the first rotating shaft 2 to rotate. The first rotating shaft 2 drives the second rotating shaft 3 to rotate through the first small gear 5 and the first large gear 6. The second rotating shaft 3 drives the third rotating shaft 4 to rotate through the second small gear 7 and the second large gear 8. The third rotating shaft 4 drives the transmission shaft 92 to rotate through the drive gear 91 and the transmission gear 93. The transmission shaft 92 drives the impeller 95 to rotate. The impeller 95 drives the lubricating oil inside the housing 1 to flow into the connecting pipe 94. After the lubricating oil passes through the filter screen 963, the impurities are filtered and left on the filter screen 963. The lubricating oil inside the housing 1 is continuously filtered through the connecting pipe 94.

[0034] When it is necessary to clean the filter screen 963, first close the first valve 97 and the second valve 98, pull the push-pull handle 965 to move the intercepting ring 962 away from the fixing ring 961, clean the filter screen 963, push the push-pull handle 965 to insert the intercepting ring 962 into the fixing ring 961, and finally open the first valve 97 and the second valve 98 to complete the cleaning of the filter screen 963.
