Abstract
The invention provides a high-order elliptic profile connected hammer drill rotational mechanism. The mechanism comprises a gear sleeve, a bit shank and a connecting sleeve, wherein the gear sleeve is connected with the connecting sleeve by adopting a high-order elliptic profile; and the connecting sleeve and the bit shank are connected by adopting the high-order elliptic profile or a spline. The rotational mechanism has the advantages that: the independent rotational guide rail type hammer drill rotational mechanism overcomes the defect of spline connection adopted by the conventional hammer drill rotational mechanism, applies the high-order elliptic profile to the connecting surface of a rotational mechanism, and provides a rotational mechanism which has the advantages of strong automatic centering capability, convenience in assembly and disassembly, concentrate stress elimination and simple matched section shape with large transfer torque, and is suitable for heavy loading. The rotational mechanism is particularly suitable for an independent rotational guide rail type hammer drill.
Description
Technical field
The present invention relates to a kind of rock drilling machinery equipment, is the hammer drill rotating drill rod mechanism that a kind of high-order elliptic surface connects specifically.
Background technology
Various rigs are widely used in the engineering explosion hole drill cutter operations such as metallurgy, railway, mine, building materials, highway.The rotating drill rod mechanism of independent circular guideway formula hammer drill is one of critical component of hammer drill.The geared sleeve of rotating drill rod mechanism adopts usually with adapter sleeve and spends strong the connection.Some shortcomings that splined can avoid common key to connect, but still exist deficiencies such as processing on can not eliminate stress concentrated, centering and the special purpose machine tool, assembling inconvenience, inconvenient maintenance.The geared sleeve of Cop1032HD type hydraulic gate adopts a kind of triangle curvilinear structures of uniqueness to be connected with adapter sleeve, and the great advantage of this structure is that transfer torque is big, thereby makes the compact conformation of rotating drill rod mechanism, and the life-span is long.But, because the particular curve that has adopted radius of curvature not wait has brought certain difficulty to processing.
Summary of the invention
In order to overcome the deficiency that above-mentioned technology exists, it is strong that technical problem to be solved by this invention provides a kind of self-centering capability, the hammer drill rotating drill rod mechanism that the high-order elliptic surface of easy accessibility, suitable heavy load connects.
Technical scheme of the present invention is: the hammer drill rotating drill rod mechanism that a kind of high-order elliptic surface connects, comprise geared sleeve, bit shank and adapter sleeve, it is characterized in that geared sleeve adopts high-order elliptic surface to be connected with adapter sleeve, adapter sleeve adopts high-order elliptic surface to be connected with bit shank or spline connects.
The cross-sectional boundaries curve of the hole that described high-order elliptic surface connects and axle is high-order elliptic curve or the oval tooth curve of high-order that obtains by inside and outside theory of engagement conjugation; The high-order elliptic curve is meant high-order elliptic curve or its equidistant curve as the profile contour curve, comprises that also the curve of the oval conjugation of high-order or its equidistant curve are as the profile contour curve.
The hole of described geared sleeve and adapter sleeve high-order elliptic surface and shaft section vertically are columns, or taper.
Advantage of the present invention is: independent circular guideway formula hammer drill rotating drill rod mechanism of the present invention has overcome the deficiency that existing hammer drill rotating drill rod mechanism adopts splined to exist, high-order elliptic surface is applied to the rotating drill rod mechanism joint face, for hammer drill provides a kind of self-centering capability strong, easy accessibility, it is concentrated to eliminate stress, cooperate the rotating drill rod mechanism that the simple transfer torque of cross sectional shape is big, be fit to heavy load, be particularly suitable for independent circular guideway formula hammer drill.
