Description

Fixing device for guide bearing outer ring of main reducer of loader

Technical Field

The utility model relates to a loader transaxle main reducer assembly structure, concretely relates to loader main reducer direction bearing inner race fixing device.

Background

In the prior art, a loader drive axle main reducer assembly generally adopts a structure as shown in fig. 1, a guide bearing 9 of the loader drive axle main reducer assembly is assembled on a guide bearing seat 8-1 of a main reducer casing 8, one end of an inner ring of the guide bearing 9 is tightly attached to a gear end face of a drive bevel gear 6, and the other end of the inner ring is fixed through a retainer ring. The main reducer assembly of the loader drive axle with the structure has the following defects: the outer ring of the guide bearing 9 is not limited and fixed, and the risk of the bearing outer ring coming off exists in the actual work process.

Disclosure of Invention

The utility model aims at overcoming above-mentioned defect, providing a simple structure, preparation and maintenance cost are low, use safe and reliable's loader main reducer direction bearing inner race fixing device to solve among the prior art direction bearing inner race because of not having the problem that spacing fixed messenger bearing inner race deviates from easily.

In order to achieve the purpose, the fixing device for the guide bearing outer ring of the main reducer of the loader comprises a main reducer shell 8 with a guide bearing seat 8-1, a fixing piece 13, a bolt 14, a gasket 15 and a nut 16; two bolt holes 8-2 are formed in the guide bearing seat 8-1; the fixing plate 13 is a semicircular steel plate, two end faces of the guide bearing seat 8-1 are respectively provided with one fixing plate, the thickness of the fixing plate 13 is 2mm-4mm, two bolt holes are also formed in the fixing plate 13, the positions of the bolt holes correspond to the positions of the bolt holes 8-2 in the guide bearing seat 8-1, and the fixing plate 13 is fixed on the guide bearing seat 8-1 through the bolts 14, the gaskets 15 and the nuts 16; the inner diameter of the fixing piece 13 is larger than the diameter of the inner ring of the guide bearing 9 and smaller than the diameter of the outer ring of the guide bearing 9, so that the outer ring of the guide bearing 9 is limited.

The fixing device for the outer ring of the guide bearing of the main reducer of the loader with the structure has the following technical characteristics and beneficial effects:

1. through increasing the stationary blade on main reducer shell as fixing device, play limiting displacement to guide bearing's outer lane, avoided the risk that guide bearing outer lane deviates from.

2. The thickness of the fixing piece is set to be 2-4mm, so that the strength of the fixing piece is guaranteed, and meanwhile the interference between the connecting bolt and the driving spiral bevel gear caused by the fact that the fixing piece is too thick is avoided.

3. The whole fixing device is simple in structure, low in manufacturing and maintenance cost and safe and reliable to use.

Detailed Description

The following describes the fixing device for the outer ring of the guide bearing of the main reducer of the loader in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 2-5, the fixing device for the outer ring of the guide bearing of the main reducer of the loader of the present invention comprises a main reducer housing 8 with a guide bearing seat 8-1, a fixing plate 13, a bolt 14, a washer 15 and a nut 16; two bolt holes 8-2 are formed in the guide bearing seat 8-1; the fixing plate 13 is a semicircular steel plate, two end faces of the guide bearing seat 8-1 are respectively provided with one fixing plate, the thickness of the fixing plate 13 is 2mm-4mm, two bolt holes are also formed in the fixing plate 13, the positions of the bolt holes correspond to the positions of the bolt holes 8-2 in the guide bearing seat 8-1, and the fixing plate 13 is fixed on the guide bearing seat 8-1 through the bolts 14, the gaskets 15 and the nuts 16; the inner diameter of the fixing piece 13 is larger than the diameter of the inner ring of the guide bearing 9 and smaller than the diameter of the outer ring of the guide bearing 9, so that the outer ring of the guide bearing 9 is limited.

As shown in fig. 1, a loader drive axle main reducer assembly before improvement mainly comprises a lock nut 1, a flange 2, an oil seal 3, a bearing seat 4, a support bearing 5, a driving spiral bevel gear 6, a spacer 7, a main reducer shell 8, a guide bearing 9, a retainer ring 10, a differential assembly 11, a driven spiral bevel gear 12 and the like; in actual operation, although the two sides of the inner ring of the guide bearing 9 are limited, the risk of separation does not exist, the outer ring of the guide bearing 9 is not limited, and the risk of separation exists. Therefore, the utility model adds 2 bolt holes on the guide bearing seat 8-1, and the positions are shown in figure 4; meanwhile, a fixing plate 13 is added, and 2 bolt holes corresponding to the guide bearing seats 8-1 are also formed in the fixing plate 13, as shown in the attached drawing 5; in order to ensure the strength of the fixing plate 13 and avoid the interference between the connecting bolt and the driving spiral bevel gear caused by the excessive thickness of the fixing plate, the thickness of the fixing plate 13 is set to be 2-4 mm; the fixing piece 13 is connected with the guide bearing mounting seat 8-1 through a connecting bolt 14, a retainer ring 15 and a nut 16, as shown in figure 3, after the guide bearing mounting seat is connected according to the structure, two end faces of the outer ring of the guide bearing 9 are limited, and the risk of separation caused by overlarge play of the outer end of the guide bearing 9 is effectively prevented.
