Description

Loader gearbox four-axis oil seal structure

Technical Field

The utility model relates to a loader gearbox equipment technical field, concretely relates to loader gearbox four-axis oil blanket structure.

Background

The oil seal is one of important sealing elements on a gearbox of a loader, and mainly has the functions of preventing oil in the gearbox from leaking and preventing foreign matters such as external dust from entering the gearbox. The oil seal is generally assembled on an inner hole of an oil seal seat in the sealing of oil liquid at four shafts of a gearbox of an existing loader, two grooves are formed in the outer circle of the oil seal seat and used for assembling O-shaped sealing rings, the outer ring of the oil seal seat and a box body are sealed through the O-shaped sealing rings, and the inner ring of the oil seal seat and the four shafts are sealed through the oil seals. The oil seal structure has the following problems in the actual production and installation process:

1. the processing requirements of the assembly surface of the inner hole of the oil seal seat and the oil seal and two grooves of the excircle of the oil seal seat are high, the processing time is long, and the labor cost is increased;

2. the oil seal seat is made of iron and is heavy; when machining, assembly oil blanket seat assembly all need artifical transport, increased workman intensity of labour.

Disclosure of Invention

The utility model aims at providing a simple high efficiency of preparation assembly, quality are reliable, low in manufacturing cost's loader gearbox four-axis oil blanket structure, solve the problem that the processing degree of difficulty is big among the prior art, intensity of labour and cost of manufacture are high.

In order to realize the purpose, the four-shaft oil seal structure of the loader gearbox comprises a box body 1, an oil seal 2 and an output flange 3; the oil seal 2 comprises an outer oil seal 2.1, an inner oil seal 2.2, an inner framework 2.3 and an outer framework 2.4, wherein the inner oil seal 2.2 is fixedly arranged on the inner framework 2.3, the outer oil seal 2.1 is fixedly arranged on the outer framework 2.4, the outer framework 2.4 is in interference fit with an inner hole of the box body 1, the inner framework 2.3 is supported on the outer framework 2.4, and the outer oil seal 2.1 and the inner oil seal 2.2 are matched with the output flange 3.

The loader gearbox four-shaft oil seal structure of above-mentioned structure is through increasing the oil blanket external diameter to with the box hole cooperation to cancel oil seal seat and the O type sealing washer among the prior art, have following technical characterstic and beneficial effect:

1. the oil seal seat and the O-shaped sealing ring are eliminated, the maintenance and the management of a material warehouse on the oil seal seat and the O-shaped sealing ring are also eliminated, the machining of a workshop on the oil seal seat is eliminated, the assembly steps are simplified, the labor intensity of workers is greatly reduced, the manufacturing cost is reduced, and meanwhile, the product percent of pass is also improved.

2. The utility model discloses an oil blanket structure is two combination oil seals, has improved product sealing performance greatly.

3. The utility model discloses simple structure, reasonable in design, the facilitate promotion has improved product quality, greatly increased the practicality.

The utility model discloses a cancel two O type sealing washers of prior art assembly on oil blanket seat and the oil blanket seat between box 1 and output flange 3, change original oil blanket into the oil blanket 2 of compriseing outer oil blanket 2.1, interior oil blanket 2.2, inner frame 2.3 and outer frame 2.4, the preparation is simple high-efficient with the assembly, has improved production efficiency and product quality greatly, alleviates workman intensity of labour, has reduced because of administrative cost and the cost of manufacture that the material diversity brought.

Drawings

Fig. 1 is the main schematic sectional view of the four-shaft oil seal structure of the loader gearbox.

Reference numerals: the oil seal box comprises a box body 1, an oil seal 2, an outer oil seal 2.1, an inner oil seal 2.2, an inner framework 2.3, an outer framework 2.4 and an output flange 3.

Detailed Description

The following describes the four-axis oil seal structure of the gearbox of the loader in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the four-shaft oil seal structure of the loader gearbox comprises a box body 1, an oil seal 2 and an output flange 3; the oil blanket 2 includes outer oil blanket 2.1, interior oil blanket 2.2, inner frame 2.3 and exoskeleton 2.4, and inner oil blanket 2.2 fixed mounting is on inner frame 2.3, and outer oil blanket 2.1 fixed mounting is on exoskeleton 2.4, this exoskeleton 2.4 and the hole interference fit of box 1, and inner frame 2.3 supports on exoskeleton 2.4, and outer oil blanket 2.1 and inner oil blanket 2.2 cooperate with output flange 3 to realize the sealed effect to fluid. During assembly, the oil seal 2 only needs to be knocked in place.
