Abstract
The utility model relates to a soft axis with long service life, which has the structure that: two ends of a soft axis with steel wire are respectively connected with a rigid joint; a narrow tube section of an opening bushing with variable diameter of each rigid joint clamps the ends of the soft axis with steel wire; a large tube section of the opening sleeve with variable diameter of each rigid joint is internally filled with an elastic sleeve, through which the soft axis with steel wire passes. The soft axis with long service life utilizes the elastic sleeve to tightly enswathe the soft axis with steel wire and causes the soft axis with steel wire to tingle under the enswathing effect of the elastic sleeve, thus changing the former rigid connecting points into elastic connecting sections, removing the former stress centralizing points on the soft axis with steel wire, greatly prolonging the service life, and increasing the average working time at least six times.
Description
Technical field
The utility model relates to a kind of driving force member, specifically a kind of long-life type flexible axle.
Background technique
In tamping equipments such as vibrating head for building, operation power all passes to the working head that vibrates by a flexible axle.And the structure of this class flexible axle generally is respectively to connect a rigid joint at the two ends of a wire soft shaft, and an end of rigid joint is the shank that can cooperate with pto or the grafting of work rod, and the other end is the reducing split coupling that there is reducing at the middle part.The tubule Duan Zaili of reducing split coupling is used for the termination of stretching into of banding wire soft shaft; The extra heavy pipe section of reducing split coupling can play certain position-limiting action that stops to the shake of wire soft shaft root outside, avoids amplitude excessive.Because wire soft shaft the time always is in dither state in work, therefore, the stress concentration point when just becoming the wire soft shaft shake with the corresponding position of the contacted wire soft shaft in reducing place of reducing split coupling in the rigid joint.Thereby the flexible axle phenomenon that often fractures herein, cause the damage of whole flexible axle to scrap.Therefore, working life, weak point was the existing ubiquitous defective of flexible axle.
The model utility content
The purpose of this utility model just provides a kind of long-life type flexible axle that can overcome this defective of frangibility effectively.
The utility model is achieved in that a kind of long-life type flexible axle, respectively connect a rigid joint at the two ends of wire soft shaft, the termination of the tubule section banding wire soft shaft of rigid joint reducing split coupling, institute's improvements are to be plugged with an elastic sleeve in the extra heavy pipe section of rigid joint reducing split coupling, and wire soft shaft passes from elastic sleeve.
Design philosophy of the present utility model is exactly to fill in the elastic sleeve of a hardness less than split coupling hardness in the extra heavy pipe section of the reducing split coupling in rigid joint, full so that extra heavy pipe section and the space between the wire soft shaft of being worn are added, utilize elastic sleeve to wrap wire soft shaft.Because the elastic reaction of elastic sleeve self, make wire soft shaft in reducing split coupling extra heavy pipe section, still can keep shake, but shake is to carry out at the parcel of elastic sleeve with under attaching, and not only jitter amplitude is limited, and can become an action integral body with elastic sleeve.Like this, original wire soft shaft and reducing split coupling reducing place are rigidly connected a little, have just become the elasticity linkage section in extra heavy pipe section elastic sleeve, and the original stress concentration point of wire soft shaft just can be eliminated thereupon, and significantly improve working life thus.Our experiments show that, fill in the average operation time of more original flexible axle of average operation time of the flexible axle after the elastic sleeve and will improve more than at least 6 times, become a kind of long-life type flexible axle of practicality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Shown in Figure 1 is a kind of long-life type flexible axle that uses on vibrating head, and this flexible axle includes two rigid joints on a wire soft shaft 2 and both sides.Being connected on wire soft shaft 2 left sides, is the vibrating head rigid joint 1 that can peg graft and cooperate with working head, and on wire soft shaft 2 the right are the power rigid joints 4 that can cooperate with the pto grafting.In two rigid joints, be equipped with reducing split coupling 5, the inserting end of tubule section banding wire soft shaft 2 under the suppression of pressure unit of reducing split coupling 5, be plugged with an elastic sleeve 4 in the extra heavy pipe section of reducing split coupling 5, wire soft shaft 2 passes from elastic sleeve.Elastic sleeve 3 can use metallic copper or aluminum to do, and also can use materials such as nonmetallic nylon or engineering plastics to make.
Claims (1)
1, a kind of long-life type flexible axle, respectively connect a rigid joint (1 at the two ends of wire soft shaft (2), 4), the termination of the tubule section banding wire soft shaft (2) of rigid joint reducing split coupling (5), it is characterized in that being plugged with an elastic sleeve (3) in the extra heavy pipe section of rigid joint reducing split coupling (5), wire soft shaft (2) passes from elastic sleeve.
