Abstract
The utility model discloses a coupling, belongs to the technical field of transmission pieces, and in particular relates to a coupling for connecting a pump for an oiling machine and a motor. The coupling comprises a plastic cylinder (7); and the upper end face of the plastic cylinder (7) is provided with a first waist-shaped groove (8) and a second waist-shaped groove (6). The utility model has the advantages that: the structure is simple, compact and reasonable, the coaxiality requirement of a pump shaft and a motor shaft is reduced, and the coupling has moderate elasticity and rigidity and has overload protection function.
Description
Technical field
The utility model designs a kind of coupling, specifically is used for oilling machine with the coupling that is connected between pump and the motor, belongs to the driving component technical field.
Background technique
As depicted in figs. 1 and 2, being used to connect oilling machine in the prior art often is to cooperate plastics outer gear sleeve 3 by metallic internal gear 2 with pump with the coupling of motor, and projection 5 between plastics outer gear sleeve 3 bosoms are provided with, one end outwards is provided with flange 4, this structure by the combination of metallic gear and plastic gear can't be avoided rigid the connection, pump shaft and motor shaft are had relatively high expectations to moderate, easily cause the motor accident of burning at the gasoline pump clamping stagnation, when stuck.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provides a kind of simple in structure, compact, reasonable; Reduce pump shaft and motor shaft to the moderate requirement, elasticity and rigidity are moderate, the coupling of tool overload protection function.
For achieving the above object, a kind of coupling of the present utility model, this coupling comprise plastic cylinder (7), first kidney slot (8) is set in plastic cylinder (7) upper-end surface, in plastic cylinder (7) upper-end surface second kidney slot (6) is set.
Preferably, described second kidney slot (6) and first kidney slot (8) are the center with plastic cylinder (7) axle center.
Preferably, described first kidney slot (8) that is positioned at the upper and lower end face concerns vertical mutually with second kidney slot (6) position.
Adopt the coupling of this programme, this coupling comprises plastic cylinder (7), at plastic cylinder (7) both ends of the surface first kidney slot (8) and second kidney slot (6) up and down, is promptly wholely made and simple in structure by plastic materials, installs simply, and elasticity and rigidity are moderate.At the gasoline pump clamping stagnation, when stuck, this coupling breaks, and has protected motor, changes a coupling with low cost and gets final product proper functioning, does not have electrical safety hidden danger.

Fig. 3 is a stereogram of the present utility model.
Fig. 4 is a plan view of the present utility model.
Fig. 5 is a worm's eye view of the present utility model.
Fig. 6 is that the A-A of Fig. 5 is to sectional view.
Embodiment
As Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, coupling of the present utility model, a kind of coupling of the present utility model, this coupling comprises plastic cylinder 7, first kidney slot 8 is set in the plastic cylinder upper-end surface, second kidney slot 6 is set in the plastic cylinder upper-end surface; Described first kidney slot and second kidney slot are the center with the plastic cylinder axle center; Described first kidney slot that is positioned at the upper and lower end face concerns vertical mutually with the second kidney slot position.
Coupling of the present utility model, because integral body is made by plastic materials, elasticity and rigidity are moderate, and be single, with low cost between structure, the tool overload protection function; Because two grooves are vertical mutually, all directions can have big gap, have reduced pump shaft and motor shaft to the moderate requirement.
