Abstract
The utility model relates to oil drilling helicoid hydraulic motor technical field, especially relates to a kind of one connecting rod universal drive shaft.Be characterized in comprising connecting rod, described connecting rod lower end is provided with hemispherical goalpost, and connecting rod bottom periphery is also provided with sheath, connecting rod is embedded by sheath and lock sleeve lives in strand, strand of living top is provided with ball seat, and be provided with bulb above ball seat, bulb embeds and is arranged in connecting rod.Its connecting rod and hemispherical goalpost one-body molded, avoid goalpost rotation and because of rotate produce wearing and tearing, structure is more stable; Bulb is connected by spheroid and cylinder, makes to increase with the contact area of ball seat, and the axial compression of bearing increases; Bulb just embeds connecting rod, seamless with connecting rod inwall, and intensity increases, and the axial compression of bearing increases further.The utility model reasonable in design, stabilized structure, the amount of reducing wear, universal drive shaft intensity increases, and application life extends.
Description
Technical field
The utility model relates to oil drilling helicoid hydraulic motor technical field, especially relates to a kind of one connecting rod universal drive shaft.
Background technology
The helicoid hydraulic motor of China is produced and is just taken on a certain scale in the middle and later periods eighties, and current conventional helical drilling rod has been standardized seriation.Some producer has taken up to study some special products, obtains certain achievement, but need to improve in working life, consumable accessory abrasion resistance etc.Wherein universal drive shaft is higher to high rigidity, abrasion resistance and the requirement in application life.But, universal drive shaft in the market, take off post and can slide, ball easily drops out, and causes universal drive shaft activity point of view little, very flexible; Ball seat and bulb contact area little, connecting rod wall is thin, and intensity is low, bears axial compression ability, fragile.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art to provide a kind of one connecting rod universal drive shaft, thus effectively solves the defect existed in prior art.
For achieving the above object, the technical scheme that the utility model is taked is: described one connecting rod universal drive shaft, be characterized in comprising connecting rod, described connecting rod lower end is provided with hemispherical goalpost, connecting rod bottom periphery is also provided with sheath, and connecting rod is embedded by sheath and lock sleeve lives in strand, and strand of living top is provided with ball seat, be provided with bulb above ball seat, bulb embeds and is arranged in connecting rod.
Described connecting rod and hemispherical goalpost are formed in one formula structure.
Described bulb is made up of arc spheroid and cylinder, and cylinder is arranged on arc spheroid upper end, and arc spheroid and cylinder are connected, and bulb upper end and connecting rod are that tight fit is connected.
The beneficial effects of the utility model are: described one connecting rod universal drive shaft, its connecting rod and hemispherical goalpost one-body molded, avoid goalpost rotation and because of rotate produce wearing and tearing, structure is more stable; Bulb is connected by spheroid and cylinder, makes to increase with the contact area of ball seat, and the axial compression of bearing increases; Bulb just embeds connecting rod, seamless with connecting rod inwall, and intensity increases, and the axial compression of bearing increases further.The utility model reasonable in design, stabilized structure, the amount of reducing wear, universal drive shaft intensity increases, and application life extends.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structural principle schematic diagram.
Shown in figure: 1. connecting rod, 2. hemispherical goalpost, 3. sheath, 4. lock sleeve, strand of 5. living, 6. ball seat, 7. bulb, 7-1. arc spheroid, 7-2, cylinder.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, described one connecting rod universal drive shaft, be characterized in comprising connecting rod 1, described connecting rod 1 lower end is provided with hemispherical goalpost 2, connecting rod 1 bottom periphery is also provided with sheath 3, and connecting rod 1 is embedded by sheath 3 and lock sleeve 4 lives in strand 5, and strand 5 top of living is provided with ball seat 6, be provided with bulb 7 above ball seat 6, bulb 7 embeds and is arranged in connecting rod 1.
Further, described connecting rod 1 and hemispherical goalpost 2 are formed in one formula structure.
Further, described bulb 7 is made up of arc spheroid 7-1 and cylinder 7-2, and cylinder 7-2 is arranged on arc spheroid 7-1 upper end, and arc spheroid 7-1 and cylinder 7-2 is connected, bulb 7 upper end with connecting rod 1 for tight fit is connected.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
