Abstract
The utility model relates to a protection type diaphragm coupling. The outer ring part of the inner side of the flange plate of the left and the right half-axle couplings 1 and 1'of the coupling composed of a middle axle 2, a left and a right half-axle couplings 1 and 1', a diaphragm 3, a diaphragm lining 4, gaskets 5 and 6 and a coupling bolt 7 is provided with flange guard rings 10 and 10', in order to prevent the diaphragm, the diaphragm lining and the gaskets from breaking and flying out.
Description
The utility model relates to diaphragm flexible shaft coupling.
Diaphragm coupling is made up of jack shaft, left and right half-coupling, diaphragm, diaphragm lining, packing ring, attachment bolt, left and right half-coupling is connected with axle head by its propeller boss, and left and right half-coupling is connected by diaphragm, diaphragm lining, packing ring, attachment bolt by its flange plate with jack shaft.This diaphragm coupling is mainly used in high-speed rotating shaft and connects, and flies out because long-term use produces diaphragm, diaphragm lining sometimes, packing ring is cracked, influences production safety.The applicant discloses a kind of safety protection type diaphragm coupling in Chinese patent LZ 92237009 in prior art, and it is to be connected with a protective housing by screw respectively to constitute on left and right half-coupling.This safety protection type diaphragm coupling, though can play protection diaphragm, diaphragm lining, packing ring is cracked flies out, and also has some shortcomings, as increased whole warp-wise size of coupling and weight, influence dynamic balancing, reduce operating life, raising production cost.
The purpose of this utility model is the shortcoming that overcomes prior art, provides one simple in structure, processes easy protection type diaphragm coupling.
Technical solution of the present utility model is that the inboard outer portion at the flange plate of the left and right half coupling of diaphragm coupling is provided with flange, forms the ring set guard ring that is connected with the half-coupling one, with prevent diaphragm, diaphragm lining, packing ring is cracked flies out.
The utility model is simple in structure, and the whole warp-wise size of coupling is little, in light weight, does not influence dynamic balancing and operating life, and cost of production is low.
Accompanying drawing 1 is the utility model structural representation.
Below in conjunction with description of drawings the utility model.
The utility model is made up of jack shaft 2, left and right half-coupling 1,1 ', diaphragm 3, diaphragm lining 4, packing ring 5,6, attachment bolt 7, left and right half-coupling 1,1 ' is connected by diaphragm 3, diaphragm lining 4, packing ring 5,6, attachment bolt 7 by its flange plate with jack shaft 2, it is characterized in that being provided with flange guard ring 10,10 ', form the ring set guard ring that is connected with the half-coupling one in the inboard outer portion of left and right half coupling 1,1 ' flange plate.
The utility model is because the flange guard ring 10,10 ' that the inboard outer portion of the flange plate of left and right half coupling is provided with is to process with semiaxis coupling 1,1 ' one, so dynamic balancing and operating life influence to coupling are very little, and process easyly, cost of production is low.
