Abstract
The invention relates to a connecting rod for a needle machine. The connecting rod comprises a major diameter part, a minor diameter part and a rod body which connected with the major diameter part and the minor diameter part, wherein the major diameter part is a circular ring which is connected with a cam on a main shaft of the needle machine; the minor diameter part is a circular ring which is combined with a push rod of the needle machine, and the middle part of the minor diameter part is in a concave shape; the cross section of the rod body is in an I shape; the major diameter part, the minor diameter part and the rod body are made of aluminum alloy, and are subjected to compression molding once; and a pit is formed on the rod body. Due to the adoption of the aluminum alloy, the connecting rod has small specific gravity; and the elastic modulus of the aluminum alloy is small, so the connecting rod has high radiating speed, light weight and high toughness and vibration resistance and can reduce the vibration of the needle machine.
Description
Technical field
The present invention relates to a kind of needing machine, relate in particular to a kind of needing machine connecting rod.
Background technology
Connecting rod is generally all done complicated motion, promptly has concurrently and moves and the parts that rotate.For example, the connecting rod that in reciprocating type prime mover, connects piston or crosshead and bent axle; The connecting rod that connects driving wheel and driven pulley in the locomotive; The cam in the needing machine on the connection main shaft and the connecting rod of push rod.
There are the following problems for existing needing machine connecting rod, turns round under no oil condition, and the bearing heat radiation is slow, temperature raises, because the thermal coefficient of expansion of connecting rod is bigger than bearing, causes in bearing top circle and the connecting rod round loosening, cause wearing and tearing and be shifted, make torsion increase severely, and finally cause connecting rod cracking; Because the metal connecting rod quality is bigger, the energy height that the needing machine reciprocating motion is consumed in order to reduce the connecting rod round frequency of acting as a travelling agent, specially increases the interior external diameter of bearing, makes bearing and rotating shaft weight increase greatly, has not only wasted material, and has increased energy consumption.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of rapid heat dissipation, in light weight, needing machine connecting rod that shock resistance is good are provided.
In order to overcome the defective that exists in the background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of needing machine connecting rod, comprise large-diameter portion, minor diameter part and the shaft that connects large-diameter portion and minor diameter part, described large-diameter portion is the annular that is connected with cam on the needing machine main shaft, described minor diameter part is the annular that combines with the needing machine push rod, is concavity in the middle of the described minor diameter part.
According to another embodiment of the invention, needing machine comprises further that with connecting rod described shaft cross section is I shape.
According to another embodiment of the invention, needing machine comprises further that with connecting rod the material of described large-diameter portion, minor diameter part, shaft is an aluminium alloy.
According to another embodiment of the invention, needing machine comprises further that with connecting rod described large-diameter portion, minor diameter part and shaft are once molding formed.
According to another embodiment of the invention, needing machine comprises further that with connecting rod described shaft is provided with pit.
The invention solves the defective that exists in the background technology, the present invention adopts aluminum alloy material, and proportion is little, and the modulus of elasticity of aluminium alloy is less, has rapid heat dissipation, in light weight, good toughness, good anti-vibration, can reduce the machine vibration of needing machine.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1;
Wherein: 1, large-diameter portion, 2, minor diameter part, 3, shaft, 4, pit.
The specific embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Shown in Fig. 1-2, a kind of needing machine connecting rod, comprise large-diameter portion 1, minor diameter part 2 and the shaft 3 that connects large-diameter portion 1 and minor diameter part 2, described large-diameter portion 1 is the annular that is connected with cam on the needing machine main shaft, described minor diameter part 2 is the annulars that combine with the needing machine push rod, is concavity in the middle of the described minor diameter part 2.
As shown in Figure 3, be the cross-sectional view of the shaft 3 of the embodiment of the invention, described shaft 3 cross sections are I shape.Needing machine shaft 3 cross sections also can be cross, king's font or ellipse herein.
Shaft 3 is provided with pit 4, not only improves the heat-sinking capability of equipment and has reduced raw material.
As the needing machine connecting rod, requiring has enough intensity and toughness, and wear-resistant, and in the present embodiment, large-diameter portion 1, minor diameter part 2, shaft 3 adopt aluminum alloy materials.The heat transfer coefficient of aluminium alloy is big, and proportion is little, and modulus of elasticity is big, good anti-vibration, and strength ratio is higher, and plasticity is good.
The centre of the cam on the needing machine main shaft is annular, large-diameter portion 1 matches with cam on the needing machine main shaft and makes annular, one end of needing machine push rod is annular, minor diameter part 2 engages with the needing machine push rod and makes annular, among the present invention, the profile of large-diameter portion 1 and minor diameter part 2 all can come as required to determine, also can be other shape.And the centre of minor diameter part 2 is concavity, is used to place the needing machine push rod.
Described large-diameter portion, minor diameter part and shaft are once molding formed.
Among the present invention, needing machine main shaft, cam, needing machine push rod are prior art, so not shown in the diagram.
During use, at first large-diameter portion 1 is connected on the cam of needing machine main shaft, places minor diameter part 2 to be the centre of concavity the needing machine push rod, by pin minor diameter part 2 and needing machine push rod are fixed then by pin.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
