Abstract
The utility model relates to a sleeve type shaft coupler which comprises a sleeve, wherein conical holes are respectively arranged inside the sleeve near the top end and the bottom end, key slots are arranged on the inner walls of the conical holes, shafts are respectively arranged inside the conical holes, key pins mutually matched with the key slots are respectively arranged on the shafts, the shafts and the conical holes are connected through the mutual insertion of the key pins and the key slots, clamp rings are clamped on the shafts arranged at the top end and the bottom end of the sleeve, and the clamp rings are fixed to the sleeve through a screw sleeve. The utility model has the advantages that the installation and the dismounting are very convenient, two conical shaft heads are arranged in two conical holes in the opposite directions and are locked by the clamping rings, the axial locking connection of two pump shafts is firm and stable, and the utility model has simple structure and low manufacture cost.
Description
Technical field
The utility model relates to a kind of case butt coupling.
Background technique
The water pump of vertical single fondational structure, the axial dimension of water pump spindle is long, need connect and compose with two pump shafts, adopts case butt coupling to connect described two pump shafts.Existing case butt coupling has a sleeve, on the sleeve inner hole wall keyway is arranged, and the spill cutting ferrule is housed in the sleeve, and sleeve one end has snap ring.During shaft coupling, connect with the termination of spill cutting ferrule earlier, again sleeve is inserted in from the other end that connects pump shaft two pump shafts, and above-mentioned cutting ferrule is inserted in the sleeve, snap ring with sleeve one end is screwed at last, and locking is the draw-in groove on a pump shaft surface wherein, so finishes the shaft coupling operation.The shortcoming of above-mentioned coupling need move big distance when being mounting or dismounting, very inconvenient.And the whole endoporus of sleeve is cylindrical hole, and by a snap ring locking sleeve, the steadiness of axially locating or shaft coupling is relatively poor.
The model utility content
The purpose of this utility model provides a kind of case butt coupling, and mounting or dismounting are convenient, and two pump shafts connect firm stable, and are simple in structure, is easy to make.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of case butt coupling, comprise sleeve, the inside of described sleeve is provided with cone shape hole respectively near top and place, bottom, the inwall of cone shape hole is provided with keyway, the inside of cone shape hole is installed axle respectively, and axle is provided with the key pin that cooperatively interacts with keyway, the mutual socket connection by key pin and keyway between axle and the cone shape hole, be arranged with snap ring on the axle of the top of described sleeve and bottom, snap ring is fixed by swivel nut and sleeve.
The beneficial effects of the utility model are: during two water pump shaft couplings, as long as the termination of two water pump spindles is done tapered, insert the cone-shaped inner hole of coupling sleeve respectively from two ends, block draw-in groove on the two taper spindle noses with the snap ring at sleeve two ends, the snap ring at two ends locks with swivel nut, promptly finishes shaft coupling work.Its dress, tear open very convenient; Two taper spindle noses, the two reverse cone shape holes of packing into are used snap ring locking, and the axial locking of two pump shafts connects firm stable; The utility model is simple in structure, low cost of manufacture.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described a kind of case butt coupling of the utility model embodiment.
Among the figure:
1, sleeve; 2, cone shape hole; 3, key pin; 4, axle; 5, snap ring; 6, swivel nut.
Embodiment
As shown in Figure 1, the described a kind of case butt coupling of the utility model embodiment, comprise sleeve 1, the inside of described sleeve 1 is provided with cone shape hole 2 respectively near top and place, bottom, and the inwall of cone shape hole 2 is provided with keyway, and the inside of cone shape hole 2 is installed axle 4 respectively, axle 4 is provided with the key pin 3 that cooperatively interacts with keyway, by the mutual socket connection of key pin 3 and keyway, be arranged with snap ring 5 on the axle of the top of described sleeve 1 and bottom between axle 4 and the cone shape hole 2, snap ring 5 is fixing with sleeve 1 by swivel nut 6.
Claims (1)
