Technical Field
[0001] The utility model relates to the technical field of reducers, in particular to an oil leakage-proof vertical reducer. Background Art
[0002] A vertical speed reducer is a type of reducer that is mounted vertically and typically secured by a flange. Primarily used in mixing mechanisms, it is a mechanical device that reduces the rotational speed of an electric motor to the desired speed. Its main structure consists of a motor, a speed reducer, an output shaft, a gear train, bearings, and a housing. It achieves speed reduction and torque amplification through an internal gear transmission system.
[0003] The existing vertical reducer is usually provided with an oil seal on the outside of the output shaft, but the oil seal is a wearing part and is prone to oil leakage after a period of use. Once the oil leakage occurs, the staff cannot find it in time, causing the oil seal to leak into the material of the mixing equipment, resulting in cost losses. Therefore, the utility model proposes an oil-leakage-proof vertical reducer. Utility Model Content
[0004] To address the problems existing in the prior art, an oil-leakage-proof vertical reducer is proposed. The vertical reducer is equipped with an oil pan, an oil baffle, an oil overflow mechanism, and an alarm mechanism. The oil baffle forms an oil receiving chamber within the oil pan. When the oil seal leaks, the oil receiving chamber begins to collect oil, which is then isolated from entering the shaft head by the oil baffle. When the liquid level in the oil receiving chamber is high, a push-type alarm is automatically activated, alerting the operator to open the oil overflow pipe and drain the oil.
[0005] The utility model proposes an oil leakage-proof vertical reducer, comprising
[0006] The reducer body has a connecting plate and an output shaft passing through the connecting plate at the bottom, an oil seal located below the connecting plate is provided on the outside of the output shaft, and an oil blocking ring is provided on the outside of the oil seal;

The anti-leakage component includes an oil overflow mechanism and an alarm mechanism, which are respectively arranged on both sides of the inside of the oil receiving pan 6, which are used to remind the staff to release the leaked oil in time.
[0023] like Figure 2 As shown, an oil-passing gap a is provided between the shaft disc 7 and the oil-blocking ring 5 , and an oil-passing gap b is provided between the oil receiving ring 8 and the oil-blocking ring 5 .
[0024] like Figure 2 As shown, both the connecting disc 2 and the shaft disc 7 are provided with through holes for the output shaft 3 to pass through, and a sealing ring a10 and a sealing ring b9 are respectively provided in the two groups of through holes.
[0025] During use, the setting of the oil receiving pan 6 ensures that when the oil seal 4 leaks oil, it first leaks into the oil receiving tank, and then flows into the oil receiving pan 6 through the oil gap b and the oil gap a in turn. The setting of the oil blocking ring 5 prevents the oil from leaking into the shaft head of the output shaft 3, thereby improving its practicality.
[0026] Example 2
