Abstract
The utility model designs a kind of Novel sleeve coupling, comprise upper bush, lower sleeve, it is characterized in that: the external diameter of the latter end of upper bush equals the internal diameter of the leading portion of lower sleeve, the outside of upper bush latter end offers outside thread, the inwall of the leading portion of lower sleeve offers internal thread, and upper bush latter end is positioned at the leading portion of lower sleeve and is threaded.On upper bush latter end, cover has nut and packing ring.On the leading portion of lower sleeve, cross-under has Cock screw to be fixed in upper bush in the leading portion of lower sleeve.The utility model has the advantages that in parallel water pump situation, same series, the pump of different model, can pass through the length changing box coupling, and without the need to again producing pump shaft, cost-saving.
Description
Technical field
The utility model relates to a kind of Novel sleeve coupling, particularly a kind of coupling that can be used in vertical long shaft pump test.
Background technique
In the test of current vertical long shaft pump, with a series of pump when testing, pump shaft is more or less the same establishing timing length, often will make different pump shafts, considerably increase cost.If a kind of convenient coupling connected can be designed, the length by regulating sleeve coupling is made up pump shaft length needed for different model water pump, make same serial water pump use same pump shaft as far as possible, can be cost-saving.
Summary of the invention
The purpose of this utility model solves in the test of vertical long shaft pump in prior art, with a series of pump when testing, pump shaft is more or less the same establishing timing length, often to make different pump shafts, cause the problem greatly increasing cost of production, a kind of Novel sleeve coupling is provided, the utility model designs a kind of Novel sleeve coupling, comprise upper bush, lower sleeve, it is characterized in that: the external diameter of the latter end of upper bush equals the internal diameter of the leading portion of lower sleeve, the outside of upper bush latter end offers outside thread, the inwall of the leading portion of lower sleeve offers internal thread, upper bush latter end is positioned at the leading portion of lower sleeve and is threaded.On upper bush latter end, cover has nut and packing ring.On the leading portion of lower sleeve, cross-under has Cock screw to be fixed in upper bush in the leading portion of lower sleeve.
The utility model has the advantages that in parallel water pump situation, same series, the pump of different model, can pass through the length changing box coupling, and without the need to again producing pump shaft, cost-saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art, and Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
A kind of Novel sleeve coupling in figure, comprise upper bush 1, lower sleeve 2, it is characterized in that: the external diameter of the latter end of upper bush equals the internal diameter of the leading portion of lower sleeve, the outside of upper bush latter end offers outside thread 3, the inwall of the leading portion of lower sleeve offers internal thread 4, and upper bush latter end is positioned at the leading portion of lower sleeve and is threaded.On upper bush latter end, cover has nut 5 and packing ring 6.On the leading portion of lower sleeve, cross-under has Cock screw 7 to be fixed in upper bush in the leading portion of lower sleeve.8 axles connected for two ends, as pump shaft and motor shaft.
Sleeve is made Novel sleeve coupling into upper bush, lower sleeve by the utility model, by regulating the connecting length of screw thread between upper and lower sleeve.Nut and packing ring have locking effect, and Cock screw is finally beaten, and play protection tightening effect, and under preventing the situations such as shutdown, screw thread return stubborn.When in parallel water pump situation, same series, the pump of different model, can pass through the length changing box coupling, and without the need to again producing pump shaft, cost-saving.
Claims (3)
1. a Novel sleeve coupling, comprise upper bush, lower sleeve, it is characterized in that: the external diameter of the latter end of upper bush equals the internal diameter of the leading portion of lower sleeve, the outside of upper bush latter end offers outside thread, the inwall of the leading portion of lower sleeve offers internal thread, and upper bush latter end is positioned at the leading portion of lower sleeve and is threaded.
2. by a kind of Novel sleeve coupling according to claim 1, it is characterized in that: on upper bush latter end, cover has nut and packing ring.
