1. Over temperature fault of reducer

導致減速器溫度過高的原因主要包括兩方面。

There are two main reasons for the high temperature of the reducer.

一，減速器在使用的過程中軸承負荷較大。大負荷狀況導致軸承之間的摩擦加劇，摩擦生熱導致零件、機械局部高溫的產生。

1、 In the process of using the reducer, the bearing load is large. The friction between bearings is intensified under the condition of heavy load, and the heat generated by friction leads to the local high temperature of parts and machinery.

二，在使用減速器的過程中油的黏度過高或過低。油的黏度可以在很大程度上增加軸承的負荷，導致軸承產生巨大的熱量。當油的黏度過大時，整體流動性大幅降低，軸承在運行的過程中需要更大的動力，這部分動力非常容易轉換為熱能，導致加速度溫度升高。而當油的黏度過小時潤滑效果降低，摩擦阻力加大，也造成軸承運轉過程中的動力增加。

2、 The viscosity of oil is too high or too low in the process of using reducer. The viscosity of the oil can increase the load of the bearing to a great extent, resulting in a huge amount of heat generated by the bearing. When the viscosity of the oil is too high, the overall fluidity is greatly reduced, and the bearing needs more power in the process of operation. This part of power is very easy to be converted into heat energy, resulting in the increase of acceleration temperature. When the viscosity of the oil is too small, the lubrication effect is reduced, the friction resistance is increased, and the power of the bearing in the process of operation is increased.

2.減速器溫度過高維修處理

2. Maintenance and treatment of too high temperature of reducer

在對減速器溫度過高進行維修處理的過程中，操作人員要對混凝土攪拌機減速器軸承進行控制，要對軸承進行定期檢查，觀察軸承的整體使用狀況。對出現異常摩擦的軸承要及時進行調整或更換，降低可能產生的局部熱量。操作人員要對油的黏度進行嚴格控制，依照設備要求及運行參數對油的密度進行計算，對黏度等級進行合理選取，降低可能出現的局部高溫.

In the process of repairing the reducer with high temperature, the operator should control the bearing of the reducer of the concrete mixer, regularly check the bearing and observe the overall service condition of the bearing. The bearing with abnormal friction should be adjusted or replaced in time to reduce the local heat. Operators should strictly control the viscosity of the oil, calculate the density of the oil according to the requirements of the equipment and operating parameters, and reasonably select the viscosity grade to reduce the possible local high temperature
