Abstract

The utility model relates to a shaft connector. Shaft holes with key grooves are arranged in two joints, the periphery of each of the two joints is provided with a disc, when convex teeth on the discs of the two joints are engaged together in a cross way, shock-proof glue is arranged among the convex teeth. A protective cover which is used for covering the shock-proof glue is an end cover, and the end cover is sheathed on two discs through one end of each of the joints and is positioned by an elastic ring and a groove on the circumferential edge of the end cover. Because the end cover is used as the protective cover for the shock-proof glue, the positioning of the end cover is realized by the match of the elastic ring with the groove on the end cover, the end cover is convenient in being sheathed on or being removed from the discs on the two joints, and the shock-proof glue between the two joints can be quickly replaced with little time and low labor consumption. The shaft connector has the advantages of simple structure, easy manufacture, low cost and high safety, and the utility model is very suitable for power transmission of various mechanical devices.

Description

A kind of shaft joint

The utility model relates to a kind of connection set of transferring power, particularly a kind of shaft joint.

Being connected generally between the output shaft of dynamic power machine and the input shaft of work mechanism will be used shaft joint, realizes transferring power as the output shaft of motor and the input shaft of water pump by shaft joint.Shaft joint normally two joints is formed, two joints are one section hollow shaft, interior axis hole for the band keyway, periphery has a circle disk, be evenly equipped with at least two double wedges on the disk, two joints when engagement the double wedge X-bite on it together and anti-vibration rubber arranged between the double wedge, disk is provided with and hides the sheath that anti-vibration rubber is used, this sheath is located at the top of placing anti-vibration rubber between the joint upper raised teeth, edge along disk stretches out, sheath can cover in anti-vibration rubber and get final product, and output and input shaft are fixedly mounted on respectively in the axis hole of the strong groove of two laced belts.But the shaft joint of this structure has a very big shortcoming: because the anti-vibration rubber in the shaft joint weares and teares easily, need often to change, during replacing, need to remove output shaft or input shaft outward, promptly motor or water pump etc. will be removed so that the anti-vibration rubber that two joints separately just can renew, therefore, the disassembly process of changing anti-vibration rubber is very loaded down with trivial details, waste time and energy, for some big machinery devices, dismounting is just extremely difficult especially.

The purpose of this utility model is to provide a kind of and need not dismantle machinery for overcoming above-mentioned shortcoming, just can be fast, save time, laborsaving, change the shaft joint of anti-vibration rubber easily.

The purpose of this utility model can be achieved as follows: this shaft joint mainly comprises two joints, two joints are one section hollow shaft, interior axis hole for the band keyway, periphery has a circle disk, be evenly equipped with at least two double wedges on the disk, two joints when engagement the double wedge X-bite on it together and anti-vibration rubber arranged between the double wedge, disk is provided with and hides the sheath that anti-vibration rubber is used, it is characterized in that: described sheath is an end cap cylindraceous, the internal diameter of its lid mouth is consistent with the end cap internal diameter, the internal diameter of end cap is bigger than the external diameter of disk on the joint, the center portion at the end cap lid end has for the joint two ends by the then intransitable perforation of disk on it, end cap is enclosed within on two disks and the groove on the cover port end cap cooperates with elastic ring and realizes the location through joint one end, wherein the part of elastic ring is stuck in the groove, and another part then is pressed on the end face of disk of cover port; Described anti-vibration rubber is wedge shape.

The utility model is owing to utilized the sheath of end cap as anti-vibration rubber, and cooperate the location of realizing end cap with an end face of disk on the groove on it and elastic ring and the joint, can on the disk on two joints, put or remove end cap easily, thus can be fast, save time, change effortlessly the anti-vibration rubber between two joints.The manufacturing simple in structure, easy of this shaft joint, cost are low, safe and reliable, are well suited in the transmission of power of various machinery to use.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the utility model shaft joint structural representation;

Fig. 2 is the A-A view of Fig. 1 in the utility model shaft joint;

Fig. 3 is the plan view of the joint of the utility model shaft joint;

Fig. 4 is that the B of Fig. 3 in the utility model shaft joint is to view;

Fig. 5 is a kind of structural representation of the elastic ring of the utility model shaft joint;

Fig. 6 is the another kind of structural representation of the elastic ring of the utility model shaft joint.

In Fig. 1 and Fig. 2, show the schematic representation that two joints 1 and 2 connect a time-out, two joints 1 and 2 are equivalent to one section hollow shaft, interior for having the axis hole 9 of keyway 5, the periphery of two joints all has a circle disk 61,62, be evenly equipped with at least two double wedges 41,42 of the same size on the disk 61,62, the disk as shown in Fig. 3 and Fig. 4 on the joint is provided with three double wedges.Double wedge 41 on the disk 61 and double wedge 42 X-bites on the disk 62 are together, simultaneously be placed with anti-vibration rubber 3 between double wedge 41 and double wedge 42, each anti-vibration rubber is wedge shape, as axe-shape, anti-vibration rubber is compressed on the limit of just pressing double wedge between double wedge like this, makes things convenient for its installation.As the sheath that hides anti-vibration rubber 3 usefulness is an end cap 7 cylindraceous; the internal diameter of its lid mouth is consistent with the end cap internal diameter; the internal diameter of end cap is bigger than the external diameter of disk on the joint 61,62; get final product slightly greatly; so that end cap relatively disk 61,62 can move freely; at the bottom of the lid of end cap there be for joint 41,42 two ends by disk 61, the 62 then intransitable perforation on it center portion; end cap is enclosed within on two disks through joint 42 1 ends; just anti-vibration rubber is hidden and protects, end cap again the groove on cover port and elastic ring 8 cooperate the location of realization to end cap.Wherein, a kind of structural type of elastic ring 8 as shown in Figure 5, wire with the circular section curves, be nick shaped, purpose is that the profile of elastic ring is diminished, conveniently in the groove of end cap cover port, install and remove, groove is a two-section perforated slot (not shown), be symmetrically distributed in cover port, tweezer elastic ring it is dwindled like this, two ringlets of the lug at its middle part and indentation, there is passed the two-section groove of cover port respectively, and be exposed, unclamp elastic ring then, whole elastic ring is stuck on the end face that also is pressed in disk 41 on the end cap simultaneously, thereby positioning action is built in the opposite end.Therefore, by the dismounting of end cap, just can change anti-vibration rubber easily.

In addition, elastic ring 8 can also be made another kind of structural type as shown in Figure 6, wire with flat curves, also be nick shaped, the profile of elastic ring also can diminish, and at this moment groove then is configured to along the groove (not shown) in an end cap lid mouthful week, and the degree of depth of this groove is littler than the cross-sectional width of elastic ring, some is pressed in the groove when guaranteeing that elastic ring is indeformable, and another part then is pressed on the end face of disk on the joint.Equally, first tweezer elastic ring dwindles it, puts the end cap cover port into, unclamps, and elastic ring just is stuck in and is pressed in simultaneously in the groove on the disk end face, builds positioning action to reach the opposite end.
