Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing embodiment.
It please refers to shown in Fig. 1-Figure 10, the utility model combined type entirety idler wheel slide plate 10 is mainly slided by slide plate frame 1, idler wheel
Piece 2, locating shaft 4 roll or the assemblings such as sliding bearing 3, roller 5 are constituted, wherein：
Slide plate frame 1 is the frame of combined type entirety idler wheel slide plate assembly, it is interior fill idler wheel slide plate 2, roll or sliding bearing 3,
Locating shaft 4, roller 5 are fitted over and are slided in the slot of rotor in the 20 outer round recessed of rotor of sliding-vane pump (as schemed at an assembly
9, shown in Figure 10).It is specific as shown in Figure 4-Figure 6, slide plate frame 1 using similar " H " type structure, bottom protrude out there are two and rotor
The forward and backward positioning region 13 of limit, this combined type entirety idler wheel slide plate 10 can be by forward and backward after being mounted in 20 sliding slot of rotor
Positioning region 13 and realize axially position.The forward and backward positioning region 13 of the present embodiment is in rectangular block shape shown in figure, its certain root
It is changed according to needed for concrete structure, and it is without being limited thereto.It hollows out to form one and idler wheel slide plate shape among the top of slide plate frame 1
The accommodation seat 11 to match, and the positioning shaft hole 12 being connect with idler wheel slide plate is opened up at the both ends of slide plate frame, it is set in axis hole 12
There is internal thread segment, to couple with the external screw thread of locating shaft 4.The bottom of accommodation seat 11 is semicircular concaved circular cambered surface, in two sides
Several circular grooves 15 are intervally distributed on concaved circular cambered surface between shape block along its length, are equipped in each groove more
A roller 5.The roller 5 is standard component, is that a kind of bearing of no retainer is placed in groove, and one group can be arranged multiple rollers,
Gap is equipped between roller and roller, when idler wheel slide plate eliminates idler wheel slide plate when operation is by radial load by roller picking-up rotation
Radial force ensure normal operation.Other than above-mentioned circular groove 15, multiple through-holes are also distributed in the bottom of slide plate frame
14, make whole idler wheel slide plate that there is certain pressure difference and centrifugal force.
Idler wheel slide plate 2 is in cylindrical type, and both ends are rotatably arranged in by locating shaft 4, bearing 3 among 1 top of slide plate frame
Accommodation seat 11 in.Specifically the centre of idler wheel slide plate 2 is equipped with axially extending bore, rolls or sliding bearing 3 is filled by being interference fitted
At the both ends of through-hole.The selection of bearing 3 is determined according to different medium, realizes that idler wheel slide plate can roll or slide rotation in slide plate frame
Turn.
Locating shaft 4 is in ladder shaft-like, has a step equipped with the positioning shaft hole 12 and bearing 3 of slide plate frame 1, front end with
Bearing 3 coordinates, and rear end couples equipped with external screw thread with the internal thread being located on slide plate frame positioning shaft hole 12, as shown in Figure 1.Also just like
Shown in Fig. 8, use as external screw thread couples with the internal thread at the both ends of slide plate frame, central diameter and slide plate frame is transition for setting on maximum diameter
Cooperation, path and bearing fit are fixed, therefore the structure of locating shaft specifically can be depending on medium, without limiting to.By locating shaft 4
And bearing 3 holds up idler wheel slide plate 2 and it is made to have gap between slide plate frame 1, and can be rotated in slide plate frame 1.
The sheet constituted is assembled by above-mentioned slide plate frame 1, idler wheel slide plate 2, locating shaft 4, rolling or sliding bearing 3 and roller 5
10 upper part of combined type entirety idler wheel slide plate is square substantially in terms of radial section, the side extended line of slide plate frame 1 with it is corresponding
The outer circle tangent line of the idler wheel slide plate 2 of side is on same straight line, as shown in Figure 2.Whole is in similar " H " type structure, with rotor 20
Outer circle groove match, as shown in Figure 1, Figure 7 shows.
Again as shown in Figure 9, Figure 10, this combined type entirety idler wheel slide plate 10 is inserted in 20 groove of rotor of sliding-vane pump, when
When 20 rotary motion of rotor, whole idler wheel slide plate 10 is in rotor slot as centrifugal force when rotating is moved out cunning, idler wheel slide plate 2
Become larger along the inlet volume for entering pump in the shell of contact sliding-vane pump and suck medium, idler wheel slide plate 2 pushes outlet of the medium to pump
Direction moves, and volume, which becomes smaller, at this time generates pressure, and idler wheel slide plate crosses outlet medium discharge.Idler wheel slide plate 2 is with pump rotor in this way
It rotates and carries out roll-sliding along pump case inner hole surface, when sliding between 2 outer circle highest point sealing surface of idler wheel slide plate and pump case
Row to volume, which becomes smaller, generates pressure, and the outer circle of idler wheel slide plate 2 at this time is transmitted to the roller of 1 circular-arc bottom face of slide plate frame by radial load
On 5, running for idler wheel slide plate is not influenced by radial load.
