Abstract
The invention discloses a power head preventing silt from intruding into a box body, and relates to the field of machinery, in particular to the technical field of manufacturing of power heads of rotary drilling rigs. The power head preventing the silt from intruding into the box body comprises a wheel hub, a key sleeve, the power box body, a driving gear and a driven gear, wherein the wheel hub and the key sleeve are fixed together through a lengthened key, the power box body is fixed on the periphery of the wheel hub in a coaxial mode, the driven gear and the wheel hub are combined into a whole in a fixed mode through a driving pin, an output shaft upper cover which is tightly matched with the power box body is fixedly connected with the upper end of the power box body, an oil seal is arranged between the output shaft upper cover and the wheel hub, a key sleeve flange is arranged above the output shaft upper cover, the key sleeve flange is fixed on the periphery of the key sleeve, the key sleeve flange and the key sleeve are arranged in an coaxial mode, a dustproof ring is arranged between the key sleeve flange and the output shaft upper cover, one end of the dustproof ring is fixedly connected to the output shaft upper cover, a dustproof groove is formed in the key sleeve flange, the other end of the dustproof ring is arranged in the dustproof groove, and grease is injected into the dustproof groove. According to the arrangement, the phenomenon that the power head cannot normally work due to the fact that the silt intrudes into the box body when the dustproof oil seal is damaged can be prevented from happening.
Description
Technical field
The present invention relates to mechanical field, particularly the manufacturing technology field of rotary digging drill power head.
Background technology
The available dynamic head is dug sand at brill, when stone, rock stratum, invade gear-box owing to the anti-dust seal wearing and tearing cause silt particle, thereby make unit head badly damaged; Therefore take effectively to prevent that the silt particle measure is most important.
Summary of the invention
The object of the invention is to provide a kind of silt that can prevent to immerse the unit head of casing, with the operate as normal of assurance unit head, and reduces the maintenance difficulty.
The present invention includes wheel hub, the key cover, power box, driven wheel, driven gear, described wheel hub and described key cover are fixed together by lengthening key, described power box is coaxial to be fixed on described wheel hub periphery, described driven wheel, driven gear is arranged in the described power box, described driven gear and described wheel hub are fixed as one by trundle, described driven wheel and the engagement of described driven gear, at the fixedly connected close-fitting output shaft loam cake with it in described power box upper end, between described output shaft loam cake and described wheel hub, oil sealing is set, key cover flange is set above described output shaft loam cake, described key cover flange is fixed on periphery and the coaxial setting of described key cover, between described key cover flange and described output shaft loam cake, dust ring is set, one end of described dust ring is fixedly connected on the described output shaft and covers, at described key cover flange dustproof groove is set, described dustproof groove is towards the output shaft loam cake, the other end of described dust ring is arranged in the described dustproof groove, injects butter in described dustproof groove.
The present invention is by arranging dust ring above power box, in key cover flange, be provided with dustproof groove simultaneously, and in dustproof groove, butter is set, it can prevent that silt immerses casing under the anti-dust seal damage situations, cause the phenomenon that unit head can't operate as normal, simultaneously, maintenance is only to need to change an anti-dust seal, do not need to clear up the silt in the casing, make maintenance difficulty reduce greatly.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
As shown in Figure 1, this unit head comprises lengthening key 1, wheel hub 3, key cover 2, power box 6, driven wheel 5, driven gear 4, wheel hub 3 is fixed together by lengthening key 1 with key cover 2, power box 6 coaxial wheel hub 3 peripheries that are fixed on, driven wheel 5, driven gear 4 is arranged in the power box 6, driven gear 4 and wheel hub 6 are fixed as one by trundle, driven wheel 5 and driven gear 4 engagements, the fixedly connected close-fitting output shaft loam cake 7 with it in power box 6 upper ends, between output shaft loam cake 7 and wheel hub 3, oil sealing 8 is set, key cover flange 10 is set above output shaft loam cake 7, key cover flange 10 is fixed on periphery and the coaxial setting of key cover 2, between key cover flange 10 and output shaft loam cake 7, dust ring 9 is set, one end of dust ring 9 is fixedly connected on the output shaft loam cake 7, at key cover flange 10 dustproof groove 11 is set, and dustproof groove 11 is towards output shaft loam cake 7, the other end of dust ring 9 is arranged in the dustproof groove 11, injects butter in dustproof groove 11.
