Summary of the invention
Water bar complex process, end ring welding technology difficulty is large, screwed hole is arranged at narrow application range on water bar deficiency are set in order to overcome in prior art, the invention provides a kind of rational in infrastructure, manufacturing process is simple, cost is low, applied widely water-cooled motor case.
The technical solution adopted for the present invention to solve the technical problems is: a kind of water-cooled motor case, it comprises an outer sleeve, an inner sleeve, two end ring and a junction block, it is characterized in that: described outer sleeve and described inner sleeve coaxially assemble, two end ring seal respectively be fixed on outer sleeve and inner sleeve two side ends on, a cooling chamber will be sealed between outer sleeve and inner sleeve; Assembling seam is shaped with inner sleeve coaxial line respectively, along evenly offering some threaded connection holes respectively with Radius on the radial end face of two end ring in the inner side of two end ring; Outer sleeve is fixed with the water inlet pipe, the outlet pipe that are communicated with cooling chamber; Described junction block sealing is fixed on one end of a sleeve, and the other end of sleeve stretches in cooling chamber through outer sleeve, and be tightly connected with the outer wall of inner sleeve, outer wall and the outer sleeve of this sleeve are sealedly and fixedly connected; Described junction block has the wiring hole being communicated with sleeve inner chamber, described inner sleeve has the wire hole being communicated with sleeve inner chamber.
Described water inlet pipe, outlet pipe are separately fixed on the outer wall close to outer sleeve two ends, symmetry axis plane.
Described junction block has terminal block pilot hole, connector cover pilot hole.
Motor case of the present invention is sealed respectively by two end ring to be fixed in outer sleeve and inner sleeve two side ends, a cooling chamber will be sealed between outer sleeve and inner sleeve, the fixing opposing open of outer sleeve, inner sleeve and two end ring, usually welding manner is selected, operating space is large, easy to manufacture, and does not arrange water bar between outer sleeve and inner sleeve, its manufacture craft is simple, and cost is low; The water inlet pipe, the outlet pipe that are communicated with cooling chamber are separately fixed on the outer tube wall close to outer sleeve two ends, symmetry axis plane, its reasonable in design, cooling water flows out through outlet pipe after entering cooling chamber by water inlet pipe, cooling water can form effective turbulent flow in cooling chamber, improves heat transference efficiency; Threaded connection hole is distributed on the radial side end face of two end ring, do not affect by position of opening, applied widely.
