Abstract

The utility model relates to an improved structure of axle center for submerged motor. The two ends of a metal rod are protruded-provided with a covered joint of a relatively-small tube diameter. The upper section of the covered joint is provided with a straightly-arranged opened grooving. A front edge and a back edge of the covered joints are provided with screw thread sections. The covered joint can be jacked into a forced ring and a wear-resistant ring loop and then is fixed on the screw thread section by screw caps so as to prolong the service life of the axes.

Description

The axle center structure-improved of heavy water power motivation

Technical field

The utility model relates to mechanical, be particularly related to a kind of axle center structure-improved of heavy water power motivation, especially refer to convex with the socket end of smaller caliber at the both-end of metallic rod body, on the socket end, cut open be provided with directly to open grooving, its forward and backward ora terminalis is provided with thread section, after can being inserted in packing ring and wear-resisting ring, being locked together on the thread section with nut again and fixing.

Background technique

Development along with society, progress of science and technology, people's life is also along with raising, the interest that people breed fish, keep pet heightens, shown in accompanying drawing 1 and accompanying drawing 2, be the heavy water power motivation of a kind of aquarium commonly used, be on preceding fixed base 11, to establish tool one intake pipe 111, one waste pipe 121 above drawing water chamber 12, it is set, the rotation of its flabellum 13 of mat, can suck current via intake pipe 111, enter in aquarium or the filter by waste pipe 121 again, to do the amount of oxygen in the supply aquarium or the work of filtering water; And the compound mode in its axle center 14 of heavy water power motivation commonly used, be that its front end directly is inserted in the axis hole 131 of flabellum 13 central interior, in addition the orientation type in the shrinkage pool 123 of 12 central shaft holes, 122 bottoms, chamber of drawing water then directly is inserted in its rear end, runs up to drive flabellum 13; Axle center 14 integral body all are with metal material or the one-body molded one-tenth one round bar body of ceramic material, in fact ceramic material moulding, though wear-resisting, material is fragile, is vibrated easy-rupturing; And the metal material moulding, though easy-rupturing not, material is not wear-resisting, and is easily frayed at its forward and backward place of being coupling, and reduces its life time, inevitably uses shortcoming so the two all still exists so far.

The model utility content

The purpose of this utility model is exactly the low shortcoming of life-span that the axle center at heavy water power motivation commonly used exists at work, a kind of axle center structure-improved of heavy water power motivation is provided, it is the socket end that convexes with smaller caliber at the both-end of a metallic rod body, on the socket end, cut open be provided with directly to open grooving, its forward and backward ora terminalis is provided with thread section, can be inserted in packing ring and wear-resisting ring behind the socket end, be locked together in fixed position on the thread section with nut again, have the characteristic of wear-resisting and anti-fracture concurrently, can effectively promote the working life in axle center.

11 for fixed base, 111 for intake pipe, 12 for the chamber of drawing water, 121 for waste pipe, 122 for central shaft hole, 123 for shrinkage pool, 13 for flabellum, 131 for axis hole, 142 for axle center, 21,21 ' for socket end, 22,22 ' for open grooving, 23,23 ' for thread section, 24,24 ' for packing ring, 25,25 ' for wear-resisting ring, 26,26 ' be nut.

Embodiment

Shown in accompanying drawing 3 and accompanying drawing 4, the axle center 2 of motor of the present utility model is the socket end 21,21 ' that convexes with smaller caliber at the both-end of a metallic rod body, on socket end 21,21 ', cut open be provided with directly to open grooving 22,22 ', its forward and backward ora terminalis is provided with thread section 23,23 ', can be inserted in packing ring 24,24 ' and wear-resisting ring 25,25 ', behind socket end 21,21 ', be locked together on the thread section 23,23 ' with nut 26,26 ' again and fix; Though this opening grooving 22,22 ' is an example with the semicircle; because its effect is to be to prevent that the wear-resisting ring 25,25 ' that is inserted in from forming the resistance system effect of sliding; so open grooving 22,22 ' form also can be set as square, hexagon or other is irregularly shaped; and this wear-resisting ring 25,25 ' material are except preferable with ceramic material; also can adopt the in addition moulding of engineering plastics, plastic-steel etc. and other the industrial wear-resistant material that can implement; if on this nut 26,26 ' surface, lay anti-skidding line etc., all still in embodiment's protection domain of the present utility model.

Combination by said elements, when the forward and backward wear-resisting ring in axle center 2 25,25 ' and the shrinkage pool of the axis hole of flabellum inside and the central shaft hole bottom, chamber of drawing water when being coupling, because wear-resisting ring 25,25 ' itself has splendid antiwear characteristic and can not wear and tear because of high speed rotating, and, metallic rod body itself can not cause rupturing because of vibration because having quite good solid rerum natura; The structural characteristics in this kind axle center 2, be material composite behaviour, do the unlike material element coupling planning of useful energy, prolonged the working life in axle center 2 according to heavy water power motivation each several part associated assembly, reduce the proportion of goods damageds in heavy water power motivation axle center 2, influence its actual effective utilization.
