Abstract
Disclosed is a shaft coupling for rigid shaft coupling, which is formed by a pipe sleeve. The outer periphery of the upper end of the pipe sleeve is equipped with left-hand threads, and the outer periphery of the lower end of the pipe sleeve is equipped with right-hand threads, the upper end of the pipe sleeve is sleeved with an upper nut, the lower end of the pipe sleeve is sleeved with a lower nut, semi-circular snap rings are respectively arranged between the upper nut and the upper end face of the pipe sleeve, and between the lower nut and the lower end face of the pipe sleeve, and the outer wall of the pipe sleeve is equipped with a pair of parallel planes. The upper end of the pipe sleeve is equipped with a V-shaped groove. The pipe sleeve is equipped with two holes. The shaft coupling is in shape of a sleeve, and an upper shaft and a lower shaft can be installed in the middle of the shaft coupling. The V-shaped groove at one end of the left-hand threads is convenient for identifying the direction of the threads. The pair of planes on the shaft coupling can be fit to a spanner, and the hole on the pipe sleeve can discharge pollutants and air, and can judge the position of the shaft, thereby increasing precision of the rigid coupling of the shaft, and the position of the shaft can be accurately judged during mounting and dismounting pumps.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to gearing, particularly a kind of shaft coupling that is used for the stiff shaft connection.
Background technique:
Often need two stiff shafts transferring power in the axial direction in the water pump, use rigid coupling to connect two axles in the prior art, but the rigid coupling precision is lower and part is all bigger, two axles when rigid joint in and coaxality accurate inadequately, adorn, tear inconvenience open, cost is higher.
Summary of the invention:
The purpose of this utility model provides a kind of shaft coupling that stiff shaft connects that is used for, described this be used for shaft coupling that stiff shaft connects to solve prior art rigid coupling precision lower and also part is all big, two axles when rigid joint in and coaxality inadequately accurately, adorn, tear open inconvenience and cost technical problems of high.
This shaft coupling that is used for the stiff shaft connection of the present utility model is made of a pipe box, wherein, the upper end excircle of described pipe box is provided with left-handed thread, the lower end excircle of pipe box is provided with right-handed thread, the upper end of pipe box is arranged with a upper cap nut, and the lower end of pipe box is arranged with a lower nut, is provided with half-round clamping ring between the upper-end surface of described upper cap nut and pipe box, be provided with half-round clamping ring between the lower end surface of lower nut and pipe box, the outer wall of pipe box is provided with the plane of pair of parallel.
Further, the upper end of described pipe box is provided with a V-type groove.
Further, described pipe box is provided with two holes.
Working principle of the present utility model is: shaft coupling is the cover type, and axle and lower shaft can be loaded onto in the centre.V-type groove at left-handed thread one end can be convenient to discern hand of spiral.Spanner can be used in the plane of the pair of parallel on the shaft coupling, and the hole on the pipe box can the blowdown thing, the position of air and judgement axle, and the precision of a rigid joint and accuracy are improved, and makes the position of judging axle in the installation and removal of pump more accurately.
The utility model and prior art contrast, and its effect is actively with tangible.The shaft coupling of the utility model utilization cover type connects goes up axle and lower shaft, the V-type groove is set is convenient to discern hand of spiral, the plane spanner easy to use of pair of parallel is set, the hole is set on the pipe box, sheet is in the position of blowdown thing, air and judgement axle, the precision of a rigid joint and accuracy are improved, and make the position of judging axle in the installation and removal of pump more accurately.
Description of drawings:
Fig. 1 is the structural representation that is used for the shaft coupling of stiff shaft connection of the present utility model.
Embodiment:
As shown in Figure 1, the shaft coupling that is used for the stiff shaft connection of the present utility model is made of a pipe box 1, wherein, the upper end excircle of described pipe box 1 is provided with left-handed thread, the lower end excircle of pipe box 1 is provided with right-handed thread, the upper end of pipe box 1 is arranged with a upper cap nut 2, the lower end of pipe box 1 is arranged with a lower nut 3, be provided with half-round clamping ring 4 between the upper-end surface of described upper cap nut 2 and pipe box 1, be provided with half-round clamping ring 5 between the lower end surface of lower nut 3 and pipe box 1, the outer wall of pipe box 1 is provided with the plane of pair of parallel.
Further, the upper end of described pipe box 1 is provided with a V-type groove.
Further, described pipe box 1 is provided with two holes 6.
Working principle of the present utility model is: shaft coupling is the cover type, and axle 7 and lower shaft 8 can be loaded onto in the centre.V-type groove at left-handed thread one end can be convenient to discern hand of spiral.Spanner can be used in the plane of the pair of parallel on the shaft coupling, and the hole 6 on the pipe box 1 can the blowdown thing, the position of air and judgement axle, and the precision of a rigid joint and accuracy are improved, and makes the position of judging axle in the installation and removal of pump more accurately.
