Detailed Description
As shown in fig. 12, the directional oil supply control mechanism for centralized lubrication of multiple oil ways comprises a shell (not shown in the figure), and a first-stage oil separator 1 and a second-stage oil separator 2 are arranged in the shell. The oil inlet end of the first-stage oil body 1 is connected with the oil inlet pipe 18 through the flow detection main body 19, the oil outlet end of the first-stage oil body 1 is connected with the second-stage oil body 2, and the second-stage oil body 2 supplies oil to a designated position through the oil outlet pipe 24. The primary oil separating body 1 and the secondary oil separating body 2 are respectively driven by a primary oil separating driving mechanism and a secondary oil separating driving mechanism, the primary oil separating driving mechanism comprises a primary driving motor 20, the primary driving motor 20 is connected with a primary encoder 21 through a coupler, and the input end of the primary driving motor 20 is connected with a primary oil separating shaft 3 of the primary oil separating body 1. The secondary oil separating and driving mechanism comprises a secondary driving motor 22, the secondary driving motor 22 is connected with a secondary encoder 23 through a coupler, and the input end of the secondary driving motor 22 is connected with the secondary oil separating shaft 10. In addition, a control unit and an oil way switch are also arranged in the shell, all the modules are sealed in the stainless steel shell, and the whole mechanism is controlled to operate by a command sent by a data line.
As shown in fig. 1-6, the first-stage oil body 1 comprises a first-stage oil separating shaft 3 and a first-stage oil separating shaft sleeve 4. The outer wall of the primary oil distributing shaft 3 is provided with a primary annular oil inlet groove 5, two primary oil channel grooves 6 are formed in the side wall of the primary oil distributing shaft 3 along the axial direction and the circumferential direction, the two oil channel grooves 6 are arranged on the primary oil distributing shaft 3 in a right-to-face mode, and each primary oil channel groove 6 is arranged up and down symmetrically by taking the primary annular oil inlet groove 5 as an equal line.
The primary oil inlet 8 and the primary oil outlet 9 are arranged on the primary oil separating shaft sleeve 4, the primary oil inlet 8 and the primary oil outlet 9 are formed by communicating a horizontal section and a vertical section for convenient processing, and the horizontal section is positioned at the outer wall end of the primary oil separating shaft sleeve for sealing. The oil inlet end of the primary oil inlet hole 8 is used for accurately feeding oil through the positive displacement flowmeter, and the oil outlet end of the primary oil inlet hole 8 is communicated with the primary annular oil inlet groove 5, and because the primary annular oil inlet groove 5 is annular, when the primary oil inlet shaft 3 rotates, the primary oil inlet hole 8 is always communicated with the primary annular oil inlet groove 5, so that continuous oil feeding is kept (vertical section oil feeding of the primary oil inlet hole 8 and horizontal section oil feeding is carried out to the primary annular oil inlet groove 5). The number of the first-stage oil outlet holes 9 is 2, the included angle of the two first-stage oil outlet holes 9 on the horizontal plane projection is 90 degrees, the horizontal sections of the two first-stage oil outlet holes 9 are arranged up and down by taking the first-stage annular oil inlet groove 5 as a demarcation line and are communicated with the oil duct groove 6 in the rotating process (the horizontal sections of the first-stage oil outlet holes 9 are used for oil inlet, and the vertical sections are used for oil outlet and flow into the second-stage oil separating body 2).
As shown in fig. 1, the two oil outlet holes 9 and the two oil passage grooves 6 are A, B, C, D, respectively. In the figure, the upper part of A and the upper part of C are opposite to each other to realize communication, so that the oil way is conducted, and the oil way B is not conducted with C or D, so that the oil way B is blocked. When the first-stage oil separating shaft 3 rotates 90 degrees clockwise, the lower part of the second-stage oil separating shaft B is opposite to the lower part of the first-stage oil separating shaft C, so that the second-stage oil separating shaft B is communicated with the lower part of the first-stage oil separating shaft C, and the first-stage oil separating shaft A is not communicated with the first-stage oil separating shaft C or the second-stage oil separating shaft D, so that the first-stage oil separating shaft A is blocked. The shaft continues to rotate 90 degrees clockwise, the a outflow channel is open, and the B outflow channel is blocked. I.e. each 90 degrees of rotation of the shaft, one of the A, B passages is formed separately to direct the oil. Thus, the oil accurately metered through the front end can form one-in two-out directional oil feeding control.
Because the purpose of the first-stage oil-separating shaft sleeve 4 is to divide the oil path into two for directional transmission, a first-stage oil-passage groove 6 can be formed in the first-stage oil-separating shaft 3, the first-stage oil-passage groove 6 is vertically symmetrically formed by taking the first-stage annular oil-inlet groove 5 as an equal line, the number of the first-stage oil-outlet holes 9 is two, the first-stage oil-outlet holes 9 are arranged on the shaft sleeve in a right-facing manner, and the included angle of the horizontal projection of the two first-stage oil-outlet holes 9 is 180 degrees. Thus, when the shaft rotates for 180 degrees, one of the two primary oil outlet holes 9 is independently conducted once.
As shown in fig. 5 to 6, the groove structure in the primary oil passage groove 6 may be replaced with a hole structure. Three through holes are transversely drilled at the position of the primary annular oil inlet groove 5 of the primary oil separating shaft 3 and the upper and lower positions, the through holes at the position of the primary annular oil inlet groove 5 are third oil passage holes 17, the through holes at the upper and lower positions are primary oil passage holes 7, in addition, a central through hole 16 is drilled at the center of the primary oil separating shaft 3 along the axial direction (the upper end of the central through hole is fixed with the communicating position of the outside through plugs, bolts and the like), and the primary oil passage holes 7, the third oil passage holes 17 and the central through hole 16 are communicated. This way also achieves the same effect as the primary oil passage groove 6.
As shown in fig. 7-11, the secondary oil body 2 comprises a secondary oil distributing shaft 10 and a secondary oil distributing shaft sleeve 11. Two secondary annular oil inlet grooves 12 are formed in the outer wall of the secondary oil separating shaft 10 along the axial direction, a secondary oil passage groove 13 is formed in each secondary annular oil inlet groove 12 along the axial direction, and the secondary oil passage grooves 13 are communicated with the secondary annular oil inlet grooves 12. The secondary oil-separating shaft sleeve 11 is provided with two secondary oil inlet holes 14, the input ends of the two secondary oil inlet holes 14 are respectively communicated with two primary oil outlet holes 9 on the primary oil-separating body 1 through pipelines, and when one primary oil outlet hole 9 in the primary oil-separating body 1 is conducted, high-pressure oil enters into the upper layer or the lower layer of secondary annular oil inlet groove 12 from the primary oil outlet hole 9. Two layers of secondary oil outlet holes 15 are arranged on the secondary oil distributing shaft sleeve 11 along the axial direction, each layer of secondary oil outlet holes 15 are circumferentially distributed in multiple layers, and the two layers of secondary oil outlet holes 15 are staggered by a certain angle.
For example: the number of the two layers of the second-level oil outlet holes 15 is 8, namely, the included angle between the adjacent second-level oil outlet holes 15 is 45 degrees. The upper layer of the second-level oil outlet holes 15 and the lower layer of the second-level oil outlet holes 15 are staggered on the horizontal projection, and the stagger angle is 22.5 degrees. The two secondary oil passage grooves 13 may be arranged in parallel or may be circumferentially offset by a certain angle. When the angle of 22.5 degrees is staggered, the motor drives the secondary oil distribution shaft 10 to rotate for 45 degrees, one of the upper and lower secondary oil inlet holes 14 can be independently conducted, and as the primary oil distribution body 1 only has one branch for supplying oil to the secondary oil distribution body 2, only one of the upper and lower secondary oil inlet holes 14 of the secondary oil distribution body 2 is used for supplying oil, so that the secondary directional conveying of an oil way is realized by one secondary oil inlet hole 14 independently.
Of course, the number of the secondary oil inlet holes 14 on the secondary oil body 2 is not limited to 16, and the principle is basically the same.
In addition, the secondary oil duct groove 13 in the secondary oil separating body 2 can also adopt a hole structure, the principle is basically the same as that of the primary oil duct hole 7, holes are all required to be punched in the central axial direction, the secondary oil inlet hole 14 corresponds to the radial position, and the radial position of the secondary annular oil inlet groove 12 is transversely punched, so that the communication between three transverse holes and one vertical hole is ensured.
Because the rotation angles of the primary oil separating shaft 3 and the secondary oil separating shaft 10 need to be precisely controlled, a driving motor connected with the primary oil separating shaft 3 and the secondary oil separating shaft 10 can be connected with an encoder through a coupler, and the driving motor is controlled by a controller, and a data line sends a command to control the whole mechanism to coordinate operation, so that the rotation angles of the primary oil separating shaft 3 and the secondary oil separating shaft 10 are precisely controlled. Under the condition that the oil inlet and outlet holes, the oil duct grooves and the oil duct holes are determined, the conduction condition of the oil way can be changed only by controlling the rotation angle, so that one inlet and one outlet (N oil ways are controlled, and are independently supplied each time, so that high pressure is ensured), and N can be 2,3,4 and the like.
The above-described embodiments are mainly directed to the case where the high-pressure oil lines are controlled in multiple orientations and supplied one-to-one. The device of the application can be practically applied to various simultaneous supply conditions, and corresponding oil inlet holes, oil outlet holes, oil passage grooves and oil passage holes are required to be reasonably arranged according to requirements.
Such as: the first-stage oil separator 1 has two branches, and can flow out independently each time. The two first-level oil outlet holes 9 are oppositely arranged (the other parts are unchanged), so that the included angle of the two first-level oil outlet holes 9 on the horizontal plane projection is 180 degrees, and the horizontal sections of the two first-level oil outlet holes 9 are arranged up and down by taking the first-level annular oil inlet groove 5 as a demarcation line. If the two oil grooves 6 are communicated with the two first-stage oil outlet holes 9 in the initial state, the two first-stage oil outlet holes 9 are blocked when the subsequent first-stage oil separating shaft 3 rotates clockwise by 90 degrees, the two oil passages are not communicated, and the two first-stage oil outlet holes 9 are communicated when the subsequent first-stage oil separating shaft rotates continuously by 90 degrees, and the two oil passages are communicated and supply oil to the second-stage oil separating body 2 (taking 16 second-stage oil outlet holes 15 as an example). The upper and lower annular oil inlet grooves 12 of the secondary oil separating body 2 are respectively filled with oil, and in the rotating process, each time the secondary oil separating body rotates for 45 degrees, the upper and lower annular oil outlet holes 15 are respectively filled with oil. Thus, the oil supply of the two oil ways can be realized at the same time. If the number of the secondary oil passage grooves or the secondary oil passage holes is increased, the condition of simultaneous oil supply by multiple oil passages (when the oil pressure is not excessively high) can be realized.
Theoretically, through the design of the number and distribution of the primary oil duct grooves 6 and the primary oil outlet holes 9, an oil way can be divided into a plurality of oil paths on the primary oil distributing shaft sleeve 4 and is controlled to flow out independently or a plurality of oil paths flow out simultaneously, but because the primary oil outlet holes 9 are communicated with the secondary oil distributing body 2 through pipelines and are branched and directionally controlled through the secondary oil distributing body 2, a plurality of groups of holes and a plurality of groups of grooves are formed on the secondary oil distributing shaft 10 along the axial direction, on one hand, the design is complicated, on the other hand, the length of the secondary oil distributing shaft 10 is overlarge, the holes and the grooves on the shaft are too many, the processing difficulty is greatly increased, the precision requirement is higher, and the secondary oil distributing shaft is easy to bend and deform; in addition, if the number of the first-stage oil outlet holes 9 is too large, the diameter of the shaft is correspondingly increased, the torque force of the motor is increased, and the power is insufficient; and because the circumference distributes, the contained angle of adjacent one-level oil outlet 9 is too little on the horizontal projection plane, like this, and motor drive axle rotation-stop cycle time is too short, must have certain error to lead to the location inaccuracy like this, and second one-level oil outlet 9 is too many, and adjacent one-level oil outlet 9 interval is too little also can make the leakproofness worsen, can lead to the emergence of oil leak condition for directional accurate oil feeding control has the error, therefore no longer introduces here one by one.
