Abstract
The utility model relates to the technical field of mechanical engineering pumps, in particular to a multistage pump thrust disc self-locking compressing device. The multistage pump thrust disc self-locking compressing device comprises a bearing disc and a pump shaft. The bearing disc is fixedly connected with the pump shaft through a key. The multistage pump thrust disc self-locking compressing device is characterized in that the device is provided with a halved ring, a tensioning ring, a compressing plate and inner hexagon screws. The halved ring comprises two half ring bodies. The compressing plate and the tensioning ring sequentially fixed sleeve the pump shaft at one end of the bearing disc. The halved ring is disposed in the annular positioning groove of the pump shaft. The tensioning ring pushes the compressing plate towards the bearing disc through the inner hexagon screws and fixes the same on the pump shaft, and accordingly complete contact of the compressing plate with the bearing disc is guaranteed so as to well transmit axial force, the axial force borne by each inner hexagon screw is the same, and the axial force borne by the bearing disc is averaged. The tensioning ring is fixedly connected with the halved ring in a sleeving manner through a radial positioning hole, so that the halved ring is radially positioned by the tensioning ring, and the tensioning ring is axially positioned by the halved ring. In addition, the multistage pump thrust disc self-locking compressing device is simple in structure, convenient to operate, time saving, labor saving, capable of avoiding shaft damage, and the like.
Description
Technical field
The utility model relates to mechanical engineering pump technical field, specifically a kind of multistage pump thrust disc auto-lock hold down.
Background technique
The compression mode that current domestic multistage pump thrust axis tray is all screw thread fastening nut on axle, higher to the requirement of screw thread on axle like this, safeguard easily damage screw thread of mounting or dismounting, the life-span of also having reduced axle simultaneously; Nut structure is easy assembling disassembling in point half bearing case, if use solid bearing case, needs to be designed to the special nut of special tool assembling, has so just improved processing and assembling difficulty.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, a kind of novel structure is provided, installs and removes conveniently, process simple multistage pump thrust disc auto-lock hold down.
The utility model solves the technological scheme that its technical problem adopts:
A kind of multistage pump thrust disc auto-lock hold down, comprise bearing dish and pump shaft, bearing dish is fixedly connected with pump shaft through key, it is characterized in that being provided with a point semi-ring, tensioning ring, pressure strip and socket head screw, described point of semi-ring is to be made up of two hemizonids, on described tensioning ring and pressure strip, a point semi-circumference is laid with at least three tapped holes, center, tensioning ring one end is provided with radial location hole, described pump shaft is provided with circular orientation groove, tapped hole on the corresponding tensioning ring in described bearing dish one end is provided with tapped blind hole, on the pump shaft of bearing dish one end, be fixed with successively pressure strip and tensioning ring, in the circular orientation groove of pump shaft, be provided with a point semi-ring, tensioning ring is pushed pressure strip to bearing dish through socket head screw, and bearing dish is fixed on pump shaft, make pressure strip ensure to transmit better axial force with contacting completely of bearing dish, and make the axial force of each socket head screw carrying identical, the axial force of bearing dish carrying is divided equally, described tensioning ring is fixedly sleeved with point semi-ring through radial location hole, so that tensioning ring radial location divides semi-ring, divide semi-ring axially locating tensioning ring.
The pretightening force direction of socket head screw described in the utility model and the axial force opposite direction of bearing dish, so just make socket head screw in the time of pump operation in squeezed state, thereby realize self-locking, without other locking device.
Hexagonal double-ended bolt head screw in socket head screw described in the utility model adopts, so that socket head screw one end is pressure strip compression axis tray, one end, by a fixing tensioning ring point semi-ring, reaches axially and the effect of radial location.
The utility model is owing to adopting said structure, have simple in structure, easy to operate, time saving and energy saving, avoid the advantages such as axle damage.
brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference character: 1, divide semi-ring 2, tensioning ring 3, socket head screw 4, pressure strip 5, thrust axis tray 6, pump shaft.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in drawings, a kind of multistage pump thrust disc auto-lock hold down, comprise bearing dish 5 and pump shaft 6, bearing dish 5 is fixedly connected with pump shaft 6 through key, it is characterized in that being provided with point semi-ring 1, tensioning ring 2, pressure strip 4 and socket head screw 3, described point of semi-ring 1 is to be made up of two hemizonids, on described tensioning ring 2 and pressure strip, a point semi-circumference is laid with at least three tapped holes, tensioning ring 2 centers, one end are provided with radial location hole, described pump shaft 6 is provided with circular orientation groove, tapped hole on the corresponding tensioning ring 2 in described bearing dish 5 one end is provided with tapped blind hole, on the pump shaft 6 of bearing dish 5 one end, be fixed with successively pressure strip 4 and tensioning ring 2, in the circular orientation groove of pump shaft 6, be provided with point semi-ring 1, tensioning ring 2 is pushed pressure strip 4 to bearing dish 5 through socket head screw 3, and bearing dish 5 is fixed on pump shaft 6, make pressure strip 4 ensure to transmit better axial force with contacting completely of bearing dish 5, and the axial force that each socket head screw 3 is carried is identical, the axial force that bearing dish 5 is carried is divided equally, described tensioning ring 2 is fixedly sleeved with point semi-ring 1 through radial location hole, so that tensioning ring radial location divides semi-ring, divide semi-ring axially locating tensioning ring, when assembling, first socket head screw 3 is screwed in tensioning ring tapped hole and with pressure strip 4 and is fitted, to divide semi-ring 1 to install on axle 6, again socket head screw 3 is screwed into one by one and holds out against point semi-ring 1, pretightening force and the torque of controlling each socket head screw 3 are basic identical, like this, the axial force that each socket head screw 3 carries is identical, the axial force that thrust axis tray 5 is carried is divided equally, the pretightening force direction of socket head screw 3 and the axial force opposite direction of thrust axis tray 5, in rotary course, socket head screw 3 is without other locking devices, this device can reach the effect of self-locking.
The utility model is owing to adopting said structure, have simple in structure, easy to operate, time saving and energy saving, avoid the advantages such as axle damage.
