Referring to the drawings,
The manifold member 12 may be a block shape or other shape that is needed for the operation of the hydraulic motor 10. The manifold member 12 may comprise an inner volume 14 that may be an aperture extending through the manifold member 12, wherein the aperture 14 may be bounded on each end by coupling the retaining plates 20 on opposing side of the manifold member 12. In embodiments, the inner volume 14 is a cylindrical shape. The manifold member 12 may also comprise an inlet orifice 13 and an outlet orifice 15. This allows hydraulic fluid to flow into the manifold member 12 through the inlet orifice 13 and into the inner volume 14 to engage and rotate the power generating member 30, and then out through the outlet orifice 15. The outlet orifice 15 has a larger opening to the inner volume 14 than the inlet orifice 13 in order to remove fluid from the inner volume as quickly as possible. An inlet hose adapter (not shown) may be coupled between the inlet orifice 13 and an inlet hose and an outlet hose adapter (not shown) may be coupled between the outlet orifice 15 and an outlet hose, thereby allowing a fluid inlet hose and a fluid outlet hose to be coupled to the manifold member 12 for operation of the device 10. The inlet orifice 13 and the outlet orifice 15 may be at any angle through the manifold member 12 to accomplish the flow of hydraulic fluid into and out of the manifold member 12. As will be understood hydraulic fluid may comprise, but is not limited to, gas, air, oil, water and the like fluids that can be flowed through the system and operate the vibration generating device 10.
In further embodiments, the inlet orifice 13 may comprise a reduce diameter portion 17 extends between the inlet orifice 13 the inner volume 14 of the manifold member 12. This reduction of diameter may operate to increase the pressure of the hydraulic fluid engaging the power generating member 30.
The manifold member 12 may comprise a protrusion 16 extending from each side and adjacent to the aperture forming a portion of the inner volume 14. The protrusion 16 may operate to extend within a recess 40 of the retaining plate 20 when the retaining plate 20 is coupled to the manifold member 12.
The manifold member 12 may have various apertures and recesses that are utilized to couple the retaining plate 20 to the manifold member and for use of couplers to couple the manifold member 12 to an external device to vibrate. While these apertures and recesses are shown, they are only for exemplary purposes and should not be considered a limitation, but simply as one way that certain components of a hydraulic motor 10 may be coupled together. Other forms of coupling components together are contemplated and may be used with departing from the scope of the invention and claims. Further, the manifold member 12 is depicted as a unitary body member. It will be understood that the manifold member 12 may comprise at least two portions that may be coupled together to form the manifold member 12.
Referring to
The power generating member 30 comprises a channeled grooved drive 36 formed in the outer surface of the spool 31 around a circumference of the spool 31. The channeled grooved drive 36 comprises a channel 37 formed in the outer surface of the spool 31 of the power generating member 30 and a plurality of recessed grooves 38 formed within the channel 37 and in the outer surface of the spool 31 around a circumference of the spool 31. The plurality of grooves 38 are evenly spaced around the circumference of the spool 31, such that hydraulic fluid may engage the grooves 38 to rotate the spool 31. The grooves 38 are shown as recesses formed in the spool 31 having fluid engaging surfaces 36 operating to rotate the power generating member 30 as fluid flowing from the inlet orifice 13 of the manifold member 12 applies force to the fluid engaging surface 35 causing a partial rotation and extends an adjacent fluid engaging surface 35 within the stream of hydraulic fluid entering through inlet orifice 13 to continuously rotate the shaft during flow of hydraulic fluid into the manifold member 12. The grooves 38 may comprise slots, notches or may further comprise tapered surfaces 39 that operate for allowing the fluid stream to engage the fluid engaging surface 35 for a longer period of time or through a longer arc to more efficiently rotate the spool 31 as will be described in greater detail with respect to
As shown in
The grooves 38 are depicted in the drawings as having a triangular shape. It will be understood that other shapes may be utilized, such as a rectangular shape, a rectilinear shape and so forth. Additionally, the size of the spool 31 may vary depending on the needed use of the motor 10. Along with the size of the spool 31, the manifold 12 will change in size to accommodate the size of the spool 31. Further still the spool 31 may comprise any number of grooves 38, the number of grooves 38 selected for the various uses needed. In addition to the number of grooves 38, the width and depth of the grooves may vary along with the width and depth of the channel 37
Further, as shown in
The hydraulic motor 10 is capable of operating in low to high pressures and operate the motor 10 in slow to high speeds. The size of the channel grooved drive 36 functions to determine the amount of pressure and the volume and rate of hydraulic fluid that is needed to flow into hydraulic motor 10 in order to rotate the power generation member 30. In other words, the depth of the channel 37 and the depth of the grooves 38 can be adjusted for the amount of fluid flow to thereby govern the amount of flow of a desired gallon per minute rate. Additionally, the inlet orifice 13 can be adjusted in size to adjust the amount of fluid flow. Typically, the larger the spool 31, the more fluid flow is needed for operation. The larger spool 31 is typically used when more mass is needed and can be accomplished by increasing the diameter of the spool 31 or may increasing the length of the spool 31. Further still, the power generation member 30 may comprise varying numbers, shapes and sizes of plurality of recessed grooves 38 of the channel grooved drive 36. For example, the size and number of the grooves, width of the grooves, and shape of the grooves operate to control or adjust the revolutions per minute and torque of the power generation member 30.
Additionally, in some embodiments, as shown in
Referring additionally to
Referring further to the drawings,
The motor 10 may be coupled to external devices to supply power to from the power generating member 30, such as gears and so forth. The motor 10 may also be scaled to various sizes as needed for the various desired power and implementation of the hydraulic motor 10.
Further still, embodiments may include a method of operating a hydraulic motor 10. The method may include directing flow of hydraulic oil into a manifold member with a power generating member coupled within the manifold member, wherein the power generating member comprises a spool comprising a channeled grooved drive having a plurality of recessed grooves; rotating the power generating member rotates in response to a portion of the hydraulic oil directed into the inner volume of the manifold member engaging one or more recessed grooves of the plurality of recessed grooves; and directing flow of hydraulic oil out of the manifold member.
The method may further comprise prior to rotating the power generating member, directing flow of hydraulic fluid through the channel until the hydraulic oil reaches operating temperature.
The method may further comprise determining torque and speed of rotation of the power generating device in response to selecting a location of the inlet orifice with respect to the fluid engaging surface, a depth and width of each recessed groove, a size of the inlet orifice, a diameter of the power generating device or combinations thereof.
The method may further comprise supplying power to an external device operatively coupled to the power generating member.
