Abstract
The utility model provides a novel guide wheel for an excavator, which comprises a wheel body, floating sealing chambers, an end cover, shafts and shaft sleeves, wherein two symmetrical oil leakage holes are arranged at the positions of the floating sealing chambers at the two ends of the wheel body; the two shaft sleeves are respectively pressed in from the two ends of the wheel body, and the end cover is fastened at one end of the wheel body; and each shaft penetrates into the other end from one end of each shaft sleeve. The novel guide wheel has the following characteristics: the structural design is reasonable and the oil leakage holes are arranged at the positions of the floating sealing chambers on the wheel body; therefore, on one hand, the oil holes are directly communicated with an oil tank and the floating sealing chambers, so that the circulation of an oil way is quite smooth, a part in need of lubrication can be timely supplemented in the serving process of the wheel body, the wearing is effectively reduced and the service life of the guide wheel is prolonged; on the other hand, as the gravity center of the wheel body is low and the mass is large, the oil leakage holes can be directly processed without a fixing device; moreover, as the requirement for the position precision is not high, the processing is convenient and the working efficiency is effectively increased.
Description
Technical field
The utility model relates to technical field of engineering machinery, is used for traxcavator domain running gear, a kind of novel excavating machine guide wheel that is specifically related to.
Background technology
Guide wheel is the important spare part of crawler doer and excavating machine and correlation engineering machine-walking system, wherein the oil sealing quality of guide wheel and skidding circulation quality are the important indicators of product, traditional guide wheel circulating oil path comprises wheel body 1, end cap 2, axle 3, floating envelope chamber 4 and axle sleeve 5 as shown in Figure 1; After oily oil hole from left side balladeur train body is injected into floating envelope chamber 4, by gap and the wheel body 1 and the gap arrival oil groove of axle sleeve 5 and the floating envelope chamber 4 of the other end of axle 3 with axle sleeve 5.Because axle sleeve 5 is relative less with the gap of axle 3 and wheel body 1, causes that easily oil circulation is not smooth; Oil circulation freely do not cause in the guide wheel military service process some component lubrication not enough and can't in time be replenished, and 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 holder guide performance, and the structure of guide wheel is optimized design, has improved the oil circulation situation effectively, and a kind of novel excavating machine guide wheel is provided.
The technical solution of the utility model is: novel excavating machine guide wheel comprises wheel body, floating envelope chamber, end cap, axle and axle sleeve; It is characterized in that: the place, floating envelope chamber at the two ends of described wheel body is provided with two symmetrical oil leaking holes; 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.
The beneficial effects of the utility model are: by the appropriate design of the utility model structure, the floating envelope chamber that oil leaking hole is changed on the wheel body is located, on the one hand, oilhole directly is communicated with oil groove and floating envelope chamber, 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 guide wheel scheme drawing;
Fig. 2 is the utility model structural representation;
The specific embodiment
As shown in Figure 2, novel excavating machine guide wheel comprises wheel body 6, floating envelope chamber 7, end cap 8, axle 9 and axle sleeve 10; It is characterized in that: 7 places, floating envelope chamber at the two ends of described wheel body 6 are provided with two symmetrical oil leaking holes 61; Two axle sleeves 10 are pressed into from wheel body 6 two ends respectively, and end cap 8 is anchored on an end of wheel body 6; Axle 9 penetrates the other end from an end by axle sleeve 10.
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.
