Abstract
The invention discloses a wedge-shaped self-locking shaft connecting device, which comprises an upper shaft and a lower shaft, and is characterized by further comprising an internal thread taper sleeve, an external thread taper sleeve, an upper key and a lower key, wherein an internal thread is formed in one end part of the inner wall of the internal thread taper sleeve; an inner hole in the other end part of the internal thread taper sleeve is a taper hole; the external thread taper sleeve is formed by combining at least two split bodies; an external thread is formed in one end part of the outer wall of the external thread taper sleeve; the other end part of the external thread taper sleeve is a tapered section; a positioning hole for allowing the end parts of the upper shaft and the lower shaft to be connected in is formed in the axis of the external thread taper sleeve; an upper key groove and a lower key groove are respectively formed in the inner side wall of the external thread taper sleeve; the external thread taper sleeve is buckled at the end parts of the upper shaft and the lower shaft butted together; the upper shaft and the lower shaft are positioned in the external thread taper sleeve through the positioning hole, the upper key and the lower key; and after the outer wall of the external thread taper sleeve is in threaded connection with the internal thread taper sleeve, the upper shaft and the lower shaft are locked through interference fit of the taper hole of the internal thread taper sleeve and the tapered section of the external thread taper sleeve. The wedge-shaped self-locking shaft connecting device has the advantages of being novel in structure, simple in processing, reliable in running, convenient and rapid to operate.
Description
Technical field
The present invention relates to mandrel connector technical field, specifically a kind of wedge shape self-locking spindle device.
Background technique
As everyone knows, in engineer applied, long shaft submerged pump uses multiple radial sliding bearing spaced apart to bear radial load usually, the radial degrees of freedom of restrictive axes system.Distance between bearing span and adjacent two sliding bearings.If adopt single shaft design when the degree of depth is darker under liquid, then manufacturability is poor, slender shaft turning difficulty.Thus adopt spindle method, many single shafts are carried out serial connection and to be inevitable selection to realize transmitting torque.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, a kind of novel structure is provided, process simple, reliable, easy to operate, quick, that there is auto-lock function wedge shape self-locking spindle device.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of wedge shape self-locking spindle device, comprise axle and lower shaft, it is characterized in that being provided with internal thread tapered sleeve, outside thread tapered sleeve, upper key and lower key, described internal thread tapered sleeve inwall one end is provided with internal thread, the endoporus of the other end is cone shape hole, described cone shape hole is reduced gradually outward by female end, described outside thread tapered sleeve is synthesized by least two split bodies, described outside thread tapered sleeve outer wall one end is provided with outside thread, tapered section of the other end, described conical section matches with cone shape hole, described outside thread matches with internal thread, outside thread tapered sleeve inwall axle center is provided with the identical positioning hole that to connect with lower shaft and upper shaft end, outside thread tapered sleeve inwall sidewall is respectively equipped with keyway and lower keyway, be beneficial to carry out axially locating to upper axle and lower shaft, described outside thread tapered sleeve is buckled in upper axle and the lower shaft end of docking, and locate through positioning hole and upper key and lower key and outside thread tapered sleeve, after outside thread tapered sleeve outer wall is threaded with internal thread tapered sleeve, by the interference fit of the cone shape hole of internal thread tapered sleeve and the conical section of outside thread tapered sleeve, by upper axle and lower shaft locking.
The present invention, owing to adopting said structure, has novel structure, processes the advantages such as simple, reliable, easy to operate, quick.
accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference character: 1. go up axle, 2. lower shaft, 3. outside thread tapered sleeve, 4. differentiate internal thread tapered sleeve, key on 5,6. descends key.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of wedge shape self-locking spindle device, comprise axle 1 and lower shaft 2, it is characterized in that being provided with internal thread tapered sleeve 3, outside thread tapered sleeve 4, upper key 5 and lower key 6, described internal thread tapered sleeve 3 inwall one end is provided with internal thread, the endoporus of the other end is cone shape hole, described cone shape hole is reduced gradually outward by female end, described outside thread tapered sleeve 4 is synthesized by least two split bodies, described outside thread tapered sleeve 4 outer wall one end is provided with outside thread, tapered section of the other end, described conical section matches with cone shape hole, described outside thread matches with internal thread, outside thread tapered sleeve 4 inwall axle center is provided with the identical positioning hole that to connect with lower shaft 2 and upper axle 1 end, outside thread tapered sleeve 4 inwall sidewall is respectively equipped with keyway and lower keyway, be beneficial to carry out axially locating to upper axle 1 and lower shaft 2, described outside thread tapered sleeve 4 is buckled in upper axle 1 and lower shaft 2 end of docking, and locate through positioning hole and upper key and lower key and outside thread tapered sleeve 4, after outside thread tapered sleeve 4 outer wall is threaded with internal thread tapered sleeve 3, by the interference fit of the cone shape hole of internal thread tapered sleeve 3 and the conical section of outside thread tapered sleeve 4, by upper axle and lower shaft locking.
The present invention when mounted, the axially locating of upper axle 1 and lower shaft 2 is located by the outside thread axle sleeve 4 differentiating body, transmitting torque is realized by upper key 5 and lower key 6, axial and radial locking and positioning is realized jointly by the outside thread tapered sleeve 4 and internal thread tapered sleeve 3 differentiating body, and this spindle method has self-locking function in the operation process of axle.Machine security, reliable operation can be ensured.And convenient processing and manufacture, all parts can be processed at engine lathe, are very beneficial to batch production.
The present invention, owing to adopting said structure, has novel structure, processes the advantages such as simple, reliable, easy to operate, quick.
