Abstract
The utility model discloses a 33 ton fork installation drive axle wheel edge sealing structure, which comprises a wheel hub 1, a rotary shaft lip-shaped sealing ring 2, an oil seal seat 3 and a brake disc 4; the oil seal seat 3 is locked on the hub 1 through an oil seal seat bolt 6; the rotary shaft lip-shaped sealing ring 2 is arranged in an inner hole of the oil seal seat 3; the brake disc 4 is locked to the hub 1 by means of brake disc bolts 5. The utility model discloses sealed effectual, the transaxle quality is reliable, the maintenance cost is low, has solved among the prior art because of the machining precision is difficult to guarantee to cause the easy direct conduction of heat that rotation axis lip seal oil leak, transaxle produced when the braking to the sealing washer cause the problem that the sealing washer became invalid.
Description
Technical Field
The utility model relates to a fork installation transaxle wheel limit seal structure technical field, concretely relates to 33 tons of fork installation transaxle wheel limit seal structure.
Background
The domestic stone forklift occupies a certain share in the field of loader subdivision, and the development of the forklift towards large tonnage is a trend, such as 33-ton forklift. In the existing 33-ton forklift loader drive axle wheel-side sealing structure, a rotary shaft lip-shaped sealing ring seat is arranged on a brake disc, and a rotary shaft lip-shaped sealing ring is arranged on the rotary shaft lip-shaped sealing ring seat. The wheel edge sealing structure of the drive axle of the 33-ton fork loader has the following defects: firstly, the diameter and the height of the brake disc are large, the machining size is not easy to guarantee, the size deviation is easy to cause, and the lip-shaped sealing ring of the rotating shaft leaks oil; secondly, the brake disc can produce a large amount of heats when the transaxle is braked, and the heat is easy to be directly conducted to the rotary shaft lip-shaped sealing ring on the brake disc, so that the rotary shaft lip-shaped sealing ring is easy to lose efficacy after long-term operation, oil leakage faults are caused, the reliability of the transaxle is reduced, and the maintenance cost is increased.
Disclosure of Invention
The utility model aims at providing a 33 tons of fork installation transaxle wheel limit seal structure that sealed effectual, transaxle quality is reliable, the maintenance cost is low solves among the prior art and is difficult to guarantee to cause the problem that rotation axis lip seal oil leak, the easy direct conduction of heat that the transaxle produced when the braking led to the fact the sealing washer to become invalid because of the machining precision.
In order to achieve the purpose, the wheel-side sealing structure of the drive axle of the 33-ton fork loader comprises a wheel hub 1, a rotary shaft lip-shaped sealing ring 2, an oil seal seat 3 and a brake disc 4; the oil seal seat 3 is locked on the hub 1 through an oil seal seat bolt 6; the rotary shaft lip-shaped sealing ring 2 is arranged in an inner hole of the oil seal seat 3; the brake disc 4 is locked to the hub 1 by means of brake disc bolts 5.
The 33 tons of fork installation transaxle wheel limit seal structure of above-mentioned structure is through optimizing design again, newly-increased oil seal seat, and oil seal seat installs on wheel hub, and rotation axis lip seal changes to oil seal seat from the brake disc on, has following technical characterstic and beneficial effect:
1. because the oil seal seat has small overall dimension and form and position tolerance is easy to guarantee, the problem of oil leakage caused by large form and position tolerance of matched parts of the lip-shaped sealing ring of the rotating shaft is avoided, and the sealing effect is improved;
2. because rotation axis lip seal and brake disc break away from, the heat after the transaxle braking can't direct conduction to rotation axis lip seal, has avoided causing the oil leak that became invalid because of operating mode high temperature problem, finally improves the transaxle reliability, increases the enterprise income.
Drawings
Fig. 1 is the main schematic cross-sectional view of the wheel-side sealing structure of the 33-ton fork-mounting machine drive axle of the present invention.
Reference numerals: wheel hub 1, rotation axis lip seal 2, oil seal seat 3, brake disc 4, brake disc bolt 5, oil seal seat bolt 6.
Detailed Description
The wheel edge sealing structure of the 33 ton fork mounting machine drive axle of the present invention is further described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the wheel-side sealing structure of the drive axle of the 33-ton fork loader of the present invention comprises a wheel hub 1, a rotary shaft lip-shaped sealing ring 2, an oil seal seat 3 and a brake disc 4; the brake disc 4 is locked on the hub 1 through a brake disc bolt 5; the oil seal seat 3 is locked on the hub 1 through an oil seal seat bolt 6, and an inner hole of the oil seal seat 3 is provided with a rotary shaft lip-shaped sealing ring 2 for sealing.
33 ton fork installation transaxle wheel limit seal structure of above-mentioned structure changes oil seal seat 3 through rotating shaft lip seal 2 from brake disc 4 on, oil seal seat 3 overall dimension is little, form and position tolerance easily guarantees, can improve the machining precision on the one hand, on the other hand because rotating shaft lip seal 2 and brake disc 4 break away from, the heat after the transaxle braking can't directly conduct rotating shaft lip seal 2, avoid rotating shaft lip seal 2 to cause the oil leak that became invalid because of the great or operating mode high temperature problem of cooperation part form and position tolerance.
