[0002] The common structure of the prior art loader drive axle main reducer assembly is that the main reducer shell is full package type, and the differential and the reducer assembly are completely in the main reducer shell. The defects of the loader drive axle main reducer assembly structure are that: 1. It is inconvenient to check the meshing condition of the driven gear during assembly; 2. When the differential is abnormal during the test run, it is impossible to check whether the differential lock is normally engaged, and the drive axle needs to be completely disassembled, which affects the work efficiency. SUMMARY

[0003] The utility model aims at providing a loader drive axle main reducer assembly structure which is simple and compact in structure, easy to assemble and efficient in operation, and solves the problems of the prior art that it is inconvenient to check the meshing condition of the driven gear during assembly and that the drive axle needs to be completely disassembled to check whether the differential lock is normally engaged when the differential is abnormal during the test run, thereby affecting the work efficiency.

[0004] To achieve the above purpose, the loader drive axle main reducer assembly structure of the utility model comprises a main reducer shell 1, an observation cover 2, bolts 3, a differential and reducer assembly 4, and an input flange 5. The main reducer shell 1 is provided with a bridge shell arm mounting flange face 1.1 and an observation hole 1.2. When the drive axle is normally installed, the observation hole 1.2 is located on the side upper end of the drive axle. The outer end face of the observation hole 1.2 is provided with four bolt holes 1.3 which are evenly distributed and used for the installation of the observation cover 2. The bridge shell arm mounting flange face 1.1 is connected with a bridge shell arm, and the differential and reducer assembly 4 is entirely wrapped in the main reducer shell 1. The observation hole 1.2 is used to directly check the meshing condition of the driven gear during assembly and the working condition of the differential lock during the test run.

[0005] The loader drive axle main reducer assembly structure of the above structure has the following technical features and beneficial effects by increasing the observation hole on the reducer shell:

[0006] 1. The meshing mark of the driven gear can be checked for abnormality when the main and driven gears are installed, and the runout of the driven gear can be detected by using a dial indicator to improve the product delivery precision.

[0007] 2. When the differential is abnormal during the test run, the differential lock can be directly checked from the observation hole 1.2 to see whether it is normally engaged, which is convenient and efficient.

[0008] 3. The observation cover 2 can also prevent the gear oil in the main reducer shell 1 from contacting the outside environment, ensuring the cleanliness of the oil.

[0009] 4、The observation hole 1.2 is arranged on the side of the drive axle, which can prevent the observation cover 2 from contacting the gear oil for a long time, and avoids the problem of oil seepage on the contact surface;

[0010] 5、The structure is simple and compact, convenient to assemble and efficient in operation. DETAILED DESCRIPTION

[0012] Figure 2 It is Figure 1 It is a three-dimensional structure schematic view after removing the observation cover and the bolt.

[0013] The observation hole 1.2 is arranged on the side of the drive axle, which can prevent the observation cover 2 from contacting the gear oil for a long time, and avoids the problem of oil seepage on the contact surface; DETAILED DESCRIPTION

[0014] The specific embodiments of the loader drive axle main reducer assembly structure will be further described in detail below with reference to the drawings.

[0015] Figures 1-2 The loader drive axle main reducer assembly structure comprises a main reducer shell 1, an observation cover 2, a bolt 3, a differential and reducer assembly 4 and an input flange 5. The main reducer shell 1 is provided with a bridge shell arm mounting flange face 1.1 and an observation hole 1.2. When the drive axle is normally installed, the observation hole 1.2 is located on the side upper end of the drive axle. The outer end face of the observation hole 1.2 is provided with four bolt holes 1.3, which are uniformly distributed and used for the installation of the observation cover 2. The bridge shell arm mounting flange face 1.1 is connected with a bridge shell arm, and the differential and reducer assembly 4 is integrally wrapped in the main reducer shell 1. The observation hole 1.2 is used to directly check the meshing condition of the driven gear during the assembly process and the working condition of the differential lock during the test run.

[0016] The loader drive axle main reducer assembly structure is provided with the observation hole 1.2 on the main reducer shell 1. Firstly, the observation hole 1.2 can be used to check whether the meshing mark of the driven gear is abnormal when the main gear and the driven gear are installed, and to detect whether the runout of the driven gear is abnormal by using a dial gauge, so as to improve the product delivery precision. Secondly, when the differential is abnormal during the test run, the observation hole 1.2 can be directly used to check whether the differential lock is normally engaged, which is convenient and efficient. Thirdly, the observation cover 2 can also prevent the gear oil in the main reducer shell 1 from contacting the outside, so as to ensure the cleanliness of the oil.
