Abstract

The utility model relates to a limit-torque plum elastic shaft coupler, which comprises a first half shaft coupler, a limit-torque disc, a first convex claw, a second convex claw, a plum elastic element, a second half shaft coupler, a pin sleeve and a safety pin, wherein the first half coupler is elastically connected with the limit-torque disc, the plum elastic element is arranged between the first convex claw and the second convex claw, and the limit-torque disc is fixedly connected with the second half shaft coupler through the pin sleeve and the safety pin. The limit-torque plum elastic shaft coupler has the advantages that the safety production function is added, so a transmission part of the equipment is prevented from being damaged, and the use and maintenance cost of the equipment is reduced.

Description

A kind of distance-limiting type plum blossom elastic coupling flexible coupling

Technical field

The utility model relates to a kind of distance-limiting type plum blossom elastic coupling flexible coupling, is a kind of coupling arrangement, belongs to mechanical field.

Background technique

Existing Quincunx elastic coupler (GB/T 5272-2002) is that the plum blossom elastic component is placed between the two half-coupling dogs, realizes the resilient connection of two half-couplings.Be characterized in simple in structure, need do not lubricate.But this coupling does not possess safety protection function.

The model utility content

Technical problem to be solved in the utility model provides a kind of distance-limiting type plum blossom elastic coupling flexible coupling, increases its safety protection function.

The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of distance-limiting type plum blossom elastic coupling flexible coupling, comprise the first half-coupling 1, limit square dish 3, the first dog 8-1, the second dog 8-2, plum blossom elastic component 2, the second half-coupling 7, guide 4, safety pin 5

Wherein, described the first half-coupling 1 is the hollow circuit cylinder body structure, enclosing disc-shaped structure near projection on the outer wall of cylindrical body one end one, be provided with the first dog 8-1 at disc-shaped structure, described limit square dish 3 is that an end is discoidal hollow circuit cylinder body structure, be provided with the second dog 8-2 at cylindrical structure, be provided with guide 4 at limit square dish 3 disc-shaped structures, described the first half-coupling 1 is connected with limit square dish 3 elasticity, described plum blossom elastic component 2 places between the first dog 8-1 and the second dog 8-2, described the second half-coupling 7 is the hollow circuit cylinder body structure, enclosing disc-shaped structure near projection on the outer wall of cylindrical body one end one, be provided with guide 4 at disc-shaped structure, described limit square dish 3 is by guide 4, safety pin 5 is fixedly connected with the second half-coupling 7.

On the basis of technique scheme, the present invention can also do following improvement.

Further, also include the lining 6 of the hollow circuit cylinder bodily form, described lining 6 places between limit square dish 3 and the second half-coupling 7, is close to the second half-coupling 7.

The beneficial effects of the utility model are: the utility model increases safety pin apparatus on the basis of existing Quincunx elastic coupler, therefore, increased safety protection function, uses the drive part of equipment to exempt from damage, reduces use and the maintenance expenses of equipment.

In the accompanying drawing, the part of each label representative is as follows:

1, the first half-coupling, 2, the plum blossom elastic component, 3, limit square dish, 4, guide, 5, safety pin,

6, lining, the 7, second half-coupling, 8-1, the first dog, 8-2, the second dog.

Embodiment

Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.

As shown in Figure 1, a kind of distance-limiting type plum blossom elastic coupling flexible coupling comprises the first half-coupling 1, limit square dish 3, the first dog 8-1, the second dog 8-2, plum blossom elastic component 2, the second half-coupling 7, guide 4, safety pin 5,

During the normal operation of the utility model distance-limiting type plum blossom elastic coupling flexible coupling, the first half-coupling 1 is installed on the shaft extension of transmission part, the second half-coupling 7 is installed on the axle of workpiece, and all coupler component parts are connected as a single entity, and transmission part is rotated with workpiece.When overburdening, safety pin 5 is cut off, and limit square dish 3 no longer is connected the working machine stall with the second half-coupling 7.Under the effect of transmission part, the first half-coupling 1, plum blossom elastic component 2 and limit square dish 3 are around lining 6 idle running, and the protection transmission part is not damaged.

The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
