The universal shaft transmission mechanism for the single-screw pump has the advantages of firm structure and good transmission effect.
Description
Technical field
The utility model relates to the mechanical technique application, and is particularly a kind of for the cardan shaft driving mechanism on the helical rotor pump.
Background technique
The cardan shaft part is short working life in the helical rotor pump that uses at present, and its main cause is that axial force and the radial force of rotor acts on the cardan shaft simultaneously, and lifting surface area is little, and moment is large, the long-time use, and the cardan shaft load is excessive, finally causes damage.
Summary of the invention
The purpose of this utility model is in order to address the above problem, to have designed a kind of for the cardan shaft driving mechanism on the helical rotor pump.
Realize that the above-mentioned purpose the technical solution of the utility model is; a kind of for the cardan shaft driving mechanism on the helical rotor pump; comprise gum cover; gum cover is enclosed within on the protecting jacket; one end port of protecting jacket docks with end cap; the other end port docks with the chock that inserts gum cover; and protecting jacket and end cap; chock is the common enclosed space that forms in gum cover; chock is equipped with ball seat towards a side of enclosed space; opposite side docks with rotor; chock; ball seat and rotor are bolted on together; ball head connecting rod passes end cap in the gum cover and is inserted on the ball seat in the above-mentioned enclosed space; stop pin laterally runs through ball head connecting rod, and at the two ends of stop pin socket slide blocks, and the port of stop pin is fixedly connected with above-mentioned enclosed space synchronously by positioning key.
Rotate synchronously by key between described chock and the rotor and dock.
Insert O type circle on described chock and the surface that rotor docks.
Described stop pin is fixed together by screw and ball head connecting rod.
Described chock and gum cover are locked by steel band and form synchronous rotational structure.
That utilizes that the technical solution of the utility model makes is used for cardan shaft driving mechanism on the helical rotor pump, the axial force of rotor is to be born by ball head connecting rod and ball seat, radial force is born by stop pin, slide blocks, chock, therefore axial force and radial force are born by each part respectively, and lifting surface area is large, ball seat and slide blocks are to adopt wear-resisting copper material, ball head connecting rod is to adopt alloyed steel surface cure process, bi-material has superpower wear resistance, the working life of therefore greatly having improved cardan shaft.

Among the figure, 1, rotor; 2, chock; 3, ball head connecting rod; 4, ball seat; 5, key; 6, gum cover; 7, protecting jacket; 8, slide blocks; 9, stop pin; 10, end cap; 11, positioning key; 12, steel bushing; 13, O type circle; 14, bolt; 15, screw.
Embodiment
Below in conjunction with accompanying drawing the utility model is specifically described; the structural representation for the cardan shaft driving mechanism on the helical rotor pump described in the utility model such as Fig. 1; as shown in the figure; a kind of for the cardan shaft driving mechanism on the helical rotor pump; comprise gum cover 6; gum cover is enclosed within on the protecting jacket 7; one end port of protecting jacket docks with end cap 10; the other end port docks with the chock 2 that inserts gum cover; and protecting jacket and end cap; chock is the common enclosed space that forms in gum cover; chock is equipped with ball seat 4 towards a side of enclosed space; opposite side docks with rotor 1; chock; ball seat and rotor are fixed together by bolt 14; ball head connecting rod 3 passes end cap in the gum cover and is inserted on the ball seat in the above-mentioned enclosed space; stop pin 9 laterally runs through ball head connecting rod, and at the two ends of stop pin socket slide blocks 8, and the port of stop pin is fixedly connected with above-mentioned enclosed space synchronously by positioning key 11.Wherein, rotate synchronously by key 5 between described chock and the rotor and dock; Insert O type circle 13 on described chock and the surface that rotor docks; Described stop pin is fixed together by screw 15 and ball head connecting rod; Described chock and gum cover are locked by steel band 12 and form synchronous rotational structure.
The characteristics of the technical program are that axial force and the radial force of rotor separately born, lifting surface area is large, long service life, axial force and the radial force of the rotor of the helical rotor pump that uses at present act on the cardan shaft simultaneously, this programme mainly sets forth axial force and radial force is born by each part respectively, and lifting surface area is large, ball seat and slide blocks are to adopt wear-resisting copper material, ball head connecting rod is to adopt alloyed steel surface cure process, bi-material has superpower wear resistance, in the working life of therefore greatly having improved cardan shaft, this programme has improved former cardan shaft and has born simultaneously axial force and radial force, the shortcoming that lifting surface area is little.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; some changes that those skilled in the art may make some part have wherein all embodied principle of the present utility model, belong within the protection domain of the present utility model.
