Abstract
The invention discloses a dynamic and static pressure ball head articulated mechanism for a heavy load and high-frequency swing working condition. The articulated mechanism provided by the invention comprises a ball head, a ball head cap, a ball head seat, an oil supply through hole and a throttler, wherein the ball head cap and the ball head seat are connected fixedly, and a ball socket is formed between the ball head cap and the ball head seat; the ball head is positioned in the ball socket; the oil supplying through hole is positioned on the jointing surface of the ball head cap and the ball head seat, and the throttler is positioned in the oil supplying through hole; and the surface of the ball socket is of a circular arc shape. According to the structure of the dynamic and static pressure ball head articulated mechanism, at the heavy load and high frequency swing working condition, the abrasion between the ball head and the ball socket is tiny, the heating quantity of the ball head articulated mechanism is less, and the service life of the ball head articulated mechanism is long.
Description
Technical field
The present invention relates to a kind of bulb linkage, specifically, relate to a kind of active and static pressure bulb linkage that is used for heavy duty and swing in high frequency operating mode.
Background technique
The bulb hinge be a kind of be that the rod member of bulb is enclosed in the mechanism in the ball-and-socket with the end, for face contacts, area of contact is big more between the two between bulb and the ball-and-socket, specific contact pressure is more little, then the fit quality of bulb linkage is good more.But, make the trend that equipment presents maximization, heavy loading, speed up along with the development of manufacturing industry technology.The bulb linkage of this kind structure the heavy duty and swing in high frequency under, the bigger force of sliding friction that will produce between bulb and the ball-and-socket, fricative heat is big.Frictional loss aggravation between bulb and the ball-and-socket is until both mutual interlocks.In order to reduce the friction between bulb and the ball-and-socket, some bulb linkages add roller between ball-and-socket and bulb.But under heavy duty and swing in high frequency operating mode, the effect that adds roller is not good yet, and still heating value is big, the life-span is short for the bulb linkage, impact resistance is relatively poor.
Summary of the invention
Technical problem:Technical problem to be solved by this invention is, a kind of active and static pressure bulb linkage that is used for heavy duty and swing in high frequency operating mode is provided, make in heavy duty and swing in high frequency operating mode, wearing and tearing between bulb and the ball-and-socket are little, and then reduce the heating value of bulb linkage, prolong the working life of bulb linkage.
Technological scheme:For solving the problems of the technologies described above, the technical solution used in the present invention is: the active and static pressure bulb linkage that is used for heavy duty and swing in high frequency operating mode of the present invention, comprise bulb, bulb lid and ball cup, the bulb lid is fixedlyed connected with ball cup, form ball-and-socket between bulb lid and the ball cup, bulb is arranged in ball-and-socket, also comprises fuel feeding through hole and flow controller, the fuel feeding through hole is positioned on the mating face of bulb lid and ball cup, and flow controller is arranged in the fuel feeding through hole; The surface of described ball-and-socket is circular arc.
Beneficial effect:Compared with prior art, adopt the beneficial effect of technological scheme of the present invention to be: in heavy duty and swing in high frequency operating mode, the wearing and tearing between bulb and the ball-and-socket are little, and the heating value of bulb linkage is little, the life-span is long, and the bearing capacity of bulb linkage is strong.In the technological scheme of the present invention, be provided with the fuel feeding through hole on the mating face of bulb lid and ball cup, be provided with flow controller in the fuel feeding through hole, form oil film wedge between bulb and the ball-and-socket.Feed lubricant oil in the fuel feeding through hole, flow of lubricant and forms the static pressure oil film in ball-and-socket in flow controller enters oil film wedge.When the bulb swing in high frequency, the static pressure oil film in the ball-and-socket will produce dynamic pressure, further improve the bearing capacity of lubricant oil, also promptly improve the bearing capacity of bulb linkage.On the other hand, because the existence of oil film, the frictional loss between ball-and-socket and the bulb is low, heating is little, the life-span is long.
Description of drawings
Fig. 1 is a structure sectional view of the present invention.
Have among the figure: bulb 1, bulb lid 2, fuel feeding through hole 3, flow controller 4, ball cup 5, ball-and-socket 6.
Embodiment
As shown in Figure 1, a kind of active and static pressure bulb linkage that is used for heavy duty and swing in high frequency operating mode of the present invention comprises bulb 1, bulb lid 2, fuel feeding through hole 3, flow controller 4 and ball cup 5.Bulb lid 2 is fixedlyed connected with ball cup 5, and forms ball-and-socket 6 between bulb lid 2 and the ball cup 5.The surface of ball-and-socket 6 is circular arc.Because the surface of ball-and-socket 6 is circular arc, so when bulb linkage swing in high frequency, can form oil film wedge between bulb 1 and the ball-and-socket 6.Bulb 1 is arranged in ball-and-socket 6.Fuel feeding through hole 3 is positioned on the mating face of bulb lid 2 and ball cup 5.Flow controller 4 is arranged in fuel feeding through hole 3.
During work, feed the lubricant oil of certain pressure in the fuel feeding through hole 3 in the active and static pressure bulb linkage of this structure, flow of lubricant is in flow controller 4 enters ball-and-socket 6.After bulb 1 placed ball-and-socket 6, the gap between bulb 1 and the ball-and-socket 6 just formed oil film wedge.After lubricant oil enters ball-and-socket 6, in oil film wedge, form the static pressure oil film.The static pressure oil film can provide the bearing capacity of bulb 1.When bulb 1 swing in high frequency, the static pressure oil film in the ball-and-socket 6 will produce dynamic pressure, further improve the bearing capacity of lubricant oil, also promptly improve the bearing capacity of bulb linkage.Lubricant oil in the oil film wedge can guarantee that ball-and-socket 6 and bulb 1 have lubricant oil to exist all the time when work.The oil film that utilizes lubricant oil to form supports external load.On the other hand, because the existence of oil film, the frictional loss between ball-and-socket 6 and the bulb 1 is low, heating is little, the life-span is long, and then the wearing and tearing between bulb and the ball-and-socket are little, and then the heating value of bulb linkage reduces the prolongation in working life of bulb linkage.Bulb linkage of the present invention is particularly useful for the occasion of heavy duty and swing in high frequency, for example loads lathe, hydraulic transmission or the like at a high speed.
Further, the upper edge, mating face between described bulb lid 2 and the ball cup 5 circumferentially evenly is provided with the fuel feeding through hole 3 of even number number.The quantity of fuel feeding through hole 3 is generally the even distribution of even number number average, for example, can be four, six or eight.But the quantity of fuel feeding through hole 3 is difficult for too much, because quantity too much can increase manufacture difficulty.The fuel feeding through hole 3 of fair amount can guarantee to provide to the bulb linkage lubricant oil of capacity.
