Abstract

The invention discloses a worm gear clutch assembly structure of a driller reduction gearbox for engineering geological investigation. The worm gear clutch assembly structure of the driller reduction gearbox for engineering geological investigation comprises a worm and a clutch. Both the worm and the clutch are hollow ring-shaped members and are both provided with center holes. The worm is provided with starlike internal teeth; the clutch is provided with starlike external teeth. The internal teeth of the worm are engaged with the external teeth of the clutch. The internal teeth of the worm and the external teeth of the clutch form an engaged gear pair of the worm gear clutch assembly structure. The abrasion resistance and the connection reliability of the worm and the clutch are increased through the engaged gear pair, so that the phenomena of auto-dropout and separation of the worm and the clutch in working process caused by the abrasion of the connecting part of the worm and the clutch are avoided efficiently. The worm gear clutch assembly structure has the advantages of being easy to manufacture, reasonable in structure, high in abrasion resistance and stable in property.

Description

The worm gear clutch assembly structure of Geo-Engineering Drills speed reducer
Technical field
The present invention relates to engineering geologic investigation equipment, specifically refer to the worm gear clutch assembly structure of Geo-Engineering Drills speed reducer.
Background technique
The speed reducer of the speed reducer transfer that to be diesel engine export rig and water pump power and water pump.Its bottom half has a worm gear and worm meshing.Worm gear empty set is on axle, and the right flank of wheel has three trapezoidal pawls.Axle is also equipped with a trapezoidal dental inlay clutch, is connected with feather key with axle.When jaw clutch is meshed with the trapezoidal pawl in worm gear side, then worm gear and axle rotate simultaneously.At two overhanging ends of axle, crank being housed drives water pump reciprocating by connecting rod.
In the probing work of engineering geologic investigation; because speed reducer worm gear engages by means of only trapezoidal pawl with clutch; rig after using a period of time trapezoidal pawl often there will be wear phenomenon; when wearing and tearing acquire a certain degree; engagement goes wrong; be easy to cause worm gear and clutch at work Automatic-falling be separated; very easily cause drilling accident; so design a kind of make simple, rational in infrastructure, resistance to wear, the rig speed reducer reinforced worm wheel of stable performance and clutch assembly structure, have great importance.
Summary of the invention
The object of this invention is to provide the worm gear clutch assembly structure of Geo-Engineering Drills speed reducer, this worm gear clutch assembly structure fabrication is simple, rational in infrastructure, abrasion resistance strong and stable performance, and can effectively prevent from joint from wearing and tearing causing worm gear and clutch at work Automatic-falling to be separated and the phenomenon of drilling accident that causes occurs, improve the Security of drilling.
Above-mentioned purpose of the present invention realizes by following technical solution: the worm gear clutch assembly structure of Geo-Engineering Drills speed reducer, comprise worm gear and clutch, described worm gear and clutch are the ring part of hollow, all there is center hole, it is characterized in that: described worm gear has star internal tooth, described clutch has star external tooth, the internal tooth of worm gear is meshed with the external tooth of clutch, the internal tooth of worm gear and the external tooth of clutch form the engaging tooth wheel set of worm gear clutch assembly structure, wearability and the connection reliability of worm gear and clutch is improved by engaging tooth wheel set, thus can effectively prevent worm gear and clutch joint from occurring wearing and tearing and causing worm gear and the clutch phenomenon that Automatic-falling is separated at work to occur.
In the present invention, described internal tooth and external tooth are 20.
Worm gear clutch assembly structure of the present invention adopts the worm gear of multiple tooth shape and multiple tooth shape clutch configuration, both are engagement easily, and engagement Du Genggao, tightr, the claw type being different from conventional drilling machine speed reducer worm gear and clutch joint designs, can effectively prevent joint wear and tear cause worm gear and clutch at work Automatic-falling be separated.
Worm gear clutch assembly structure in the present invention in use, when the external tooth of star clutch is not meshed with star worm gear side star internal tooth, then only worm screw band dynamic clutch rotates, when the external tooth of star clutch is meshed with star worm gear side star internal tooth, then worm gear rotates with worm screw under the drive of clutch simultaneously.
Compared with prior art, the present invention has following significant effect:
Existing rig speed reducer worm gear and clutch joint design for claw type, the right flank of worm gear has three trapezoidal pawls, clutch side is trapezoidal dental inlay, worm gear engages by means of only trapezoidal pawl with clutch, trapezoidal pawl has a shortcoming, and degree of engagement is not high exactly, by means of only three trapezoidal pawls engagements, once rig after using a period of time trapezoidal pawl there is wear phenomenon, be easy to cause worm gear and clutch at work Automatic-falling be separated, very easily cause drilling accident.
Enforcement of the present invention, in rig speed reducer working procedure, worm gear is engaged by worm gear 20 internal tooths and clutch 20 external tooths with clutch, engagement Du Genggao, more closely, can effectively prevent joint wear and tear cause worm gear and clutch at work Automatic-falling be separated, make simple, rational in infrastructure, resistance to wear, stable performance.
