Abstract

An excavator support chain wheel comprises an end cover, a wheel body, two shaft sleeves, a floating-sealing ring assembly, a support cover, an O-shaped sealing ring and a shaft, wherein the wheel body is provided with an oil leakage hole which is directly communicated with an oil groove and the floating-sealing ring assembly; the two shaft sleeves are respectively pressed in from two ends of the wheel body, and the end cover is fastened at one end of the wheel body; the shaft penetrates through the other end from one end by the shaft sleeves; the O-shaped sealing ring is arranged in the groove at one end of the shaft; the floating-sealing ring assembly is arranged in the supporting cover, and simultaneously the supporting cover is pressed at the other end of the wheel body; the oil leakage hole in the original shaft is improved to be arranged in the wheel body, therefore, on the one hand, the oil hole is directly connected with the oil groove and the floating-sealing assembly, so that the oil path circulation is extremely smooth, the parts needing to be lubricated can be supplemented timely during the serving process of the wheel body, the abrasion is effectively reduced, and the service life of a product is further prolonged; and on the other hand, as the gravity center of the wheel body is low, the mass is large, the oil leakage hole can be directly processed without needing a fixing device, and the position accuracy requirement is low so that the process is convenient, and the working efficiency is further effectively improved.

Description

A kind of excavating machine track carrying wheel

Technical field

The utility model relates to technical field of engineering machinery, is used for traxcavator domain running gear, a kind of excavating machine track carrying wheel that is specifically related to.

Background technology

Track carrying wheel is the important spare part of crawler doer and excavating machine and correlation engineering machine-walking system, and its bearing load is less, has certain directional tagging, and its life-span is longer relatively.And the circulating oil path of traditional track carrying wheel as shown in Figure 1, and traditional track carrying wheel comprises end cap 8, wheel body 9, axle sleeve 10, floating envelope chamber 11, cover 12, O RunddichtringO 13, spools 14; Described axle 14 is provided with oil leaking hole 141; After oil injects from the left side, flow into arrival oil groove and floating envelope chamber 11 by the oil leaking hole on the axle 14 141; This method causes oil circulation not smooth easily, and its reason is present in:

1, deviation to some extent unavoidably during the position of the oil leaking hole 141 on processing axle 14 adds that oil leaking hole 141 diameters are originally not smooth with regard to the little oil circulation that causes easily;

2, axle sleeve 10 is very little in the gap of axle 14 and wheel body 9, and leakage of oil is also difficult relatively;

More than two kinds of situations because oil circulation does not freely cause causing in the track carrying wheel military service process parts skidding not enough and can't in time be replenished, aggravated the service life that product has been shortened in its wearing and tearing.

Summary of the invention

The purpose of this utility model is not influence under the situation of track carrying wheel performance, and the structure of track carrying wheel is optimized design, has improved the oil circulation situation effectively, and a kind of excavating machine track carrying wheel is provided.

The technical solution of the utility model is: a kind of excavating machine track carrying wheel comprises end cap, wheel body, axle sleeve, floating sealing ring assembly, a lid, O RunddichtringO, axle; It is characterized in that: be provided with oil leaking hole on described wheel body, described oil leaking hole is directly to be communicated with oil groove and floating sealing ring assembly;

Two axle sleeves are pressed into from the wheel body two ends respectively, and end cap is anchored on an end of wheel body; Axle penetrates the other end from an end by axle sleeve, and the O RunddichtringO of in the groove of axle one end, packing into, and, will prop up the other end that lid is pressed on wheel body simultaneously with the floating sealing ring assembly Zhi Gainei that packs into.

The beneficial effects of the utility model are: by the appropriate design of the utility model structure, oil leaking hole on original axle is changed on the wheel body, on the one hand, oilhole directly is communicated with oil groove and floating sealing ring assembly, make its oil circulation very smooth and easy like this, in wheel body military service process, can in time replenish the position that needs skidding, effectively reduce wearing and tearing, thereby prolonged the service life of product; On the other hand, because the wheel body center of gravity is low, quality is big, need not anchor fitting and just can directly process oil leaking hole, and position accuracy demand is not high is convenient to processing, thereby effectively improved work efficiency.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in detail;

Fig. 1 is traditional track carrying wheel scheme drawing;

Fig. 2 is the utility model structural representation;

The specific embodiment

As shown in Figure 2, a kind of excavating machine track carrying wheel comprises end cap 1, wheel body 2, axle sleeve 3, floating sealing ring assembly 4, cover 5, O RunddichtringO 6, spools 7; Be provided with oil leaking hole 21 on described wheel body 2, described oil leaking hole 21 is directly to be communicated with oil groove and floating sealing ring assembly 4;

Two axle sleeves 3 are pressed into from wheel body 2 two ends respectively, and end cap 1 is anchored on an end of wheel body 2; Axle 7 penetrates the other end from an end by axle sleeve 3, and the O RunddichtringO 6 of packing in the groove of axle 7 one ends, and floating sealing ring assembly 4 packed into covers in 5, will prop up simultaneously to cover 5 other ends that are pressed on wheel body 2.

The utility model processing is easy, and oil circulation is smooth and easy, has improved the variety of problems that does not freely cause owing to oil circulation effectively, has prolonged the service life of product simultaneously, has strengthened the market competitiveness.

Claims

1. an excavating machine track carrying wheel comprises end cap, wheel body, axle sleeve, floating sealing ring assembly, a lid, O RunddichtringO, axle; Two axle sleeves are pressed into from the wheel body two ends respectively, and end cap is anchored on an end of wheel body; Axle penetrates the other end from an end by axle sleeve, and the O RunddichtringO of in the groove of axle one end, packing into, and, will prop up the other end that lid is pressed on wheel body simultaneously with the floating sealing ring assembly Zhi Gainei that packs into; It is characterized in that: be provided with oil leaking hole on described wheel body, described oil leaking hole is directly to be communicated with oil groove and floating sealing ring assembly.
