Abstract
The utility model discloses a motor with a sealed pad on the bottom of a terminal box. The connecting point of a motor stator 1 and a motor terminal box 2, i.e. the bottom of the motor terminal box is added with a sealed pad made of heat resisting rubber, and the sealed pad is provided with holes with definite quantity according to the installing size of the terminal box and the position of a winding leading-out wire 4 of the motor stator. The design meets the operating requirements of the motor with sealed pad on the bottom of terminal box as well as effectively isolates and separates the motor terminal box from the motor stator. The utility model thoroughly solves the problem that components in the terminal box are desquamated to result in damaging the motor with sealed pad on the bottom of terminal box, and effectively reduces the repair rate of the motor with sealed pad on the bottom of terminal box.
Description
Affiliated technical field:
The utility model relates to the Sealing Technology of motor.Concrete is the motor of terminal box tail band sealing gasket.
Background technology:
The motor that uses on the domestic market adopts a kind of sealing ring identical with the terminal box shape at motor stator with the junction of terminal box at present.The cross section of circle is an O shape, and material is a heat resistant rubber, and this sealing ring mainly is to be sealed damp-proof.Prevent that moisture and wet gas from entering bore of stator.The bore of stator of the motor of this spline structure communicates with the terminal box chamber, installs the binding post of input stator current lead in the terminal box.All be to compress this connecting mode of lead on the binding post at present with packing ring and nut, in motor operation course, produce vibrations and very easily cause the loosening of interior these nuts of terminal box, cause nut, packing ring to come off, thereby in the bore of stator of the motor into of dropping, cause motor stator winding line short, puncture, make whole motor damage, paralyse.
Summary of the invention:
The technical problems to be solved in the utility model is to eliminate nut, packing ring in the terminal box into motor stator chamber of dropping, thereby causes stator winding line short, puncture, improves the useful life of motor.
The utility model is to overcome the above problems the technical scheme of taking to be, the motor stator chamber is designed to the sealing gasket identical with the terminal box Bottom Shape with the sealing ring of connection place, terminal box chamber, the position of corresponding terminal box internal wiring terminal on the position, intermediate portion, leaving some diameters can be by the hole of motor stator winding lead-out wire.
Its cross section of all edges of sealing gasket can be O shape, can be rectangle, can be ellipse, can be arbitrary shape, still plays sealing ring and prevents that stator from making moist.The sealing gasket middle part can with all edges condition of equivalent thickness, but consider economical with materials, reduce cost, design slightly thinlyyer than all edges, for having the film of certain intensity, its intensity reaches and prevents the nut collar fall impacting and damaged getting final product.The material of sealing gasket with now use the identical of motor sealing ring.
During use sealing gasket placed motor stator chamber and terminal box connection place, install terminal box, its winding lead-out wire has just been stretched in the corresponding hole of sealing gasket, the specification requirement of lead-out wire by design is connected on the binding post of terminal box, by technical specification packing ring is placed, nut screws, and installs connector cover, and the installation of sealing gasket is promptly finished.
Its effect is the sealed damp-proof that guarantees the motor stator chamber.Bore of stator and terminal box chamber are isolated, prevented that packing ring on the terminal box internal wiring terminal and nut from producing because of motor rotates after vibrations come off, and falls in the bore of stator.Avoided nut directly to contact and be short-circuited, caused winding to puncture, whole motor damaged with stator winding.The application of this design has improved the useful life of motor greatly, has reduced the motor repair rate, has produced good economic benefit.

Embodiment:
Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.
Embodiment 1: settle sealing gasket 3 at motor stator 1 accent and motor connecting cartridge 2 Di Kou connection places, be provided with circular hole with stator lead-out wire 4 corresponding positions on the sealing gasket 3, lead-out wire 4 passes from circular hole.The threephase asynchronous stator lead-out wire should have 6, is connected respectively on the corresponding binding post of terminal box by the hole.Place packing ring by technical specification, screw nut, install connector cover.Sealing gasket 3 all edges, its cross section is an O shape, the centre is thinner, in corresponding position distribution 8 holes, wherein 6 holes are passed through for the threephase asynchronous stator lead-out wire above, and middle 2 holes are the link plate hole, link box hole is to join brill when assembling, does not therefore occur in accompanying drawing 2.
Embodiment 2: in motor stator 1 accent and motor connecting cartridge 2 Di Kou connection places, settle sealing gasket 3, be provided with circular hole with stator lead-out wire 4 corresponding positions on the sealing gasket 3, lead-out wire 4 passes from circular hole, and Y90 motor stator lead-out wire should have 6.Be connected respectively on the corresponding binding post of terminal box by the hole.Place packing ring by technical specification, screw nut, install connector cover.Sealing gasket 3 its cross sections of all edges are rectangle, and the centre is thinner, and above in corresponding position distribution 4 holes, wherein bigger 2 holes are passed through for Y90 motor stator lead-out wire, 3 lines in every hole, and other 2 holes are the terminal block fixing hole, join brill during the assembling of terminal box fixing hole.
Embodiment 3: settle sealing gasket 3 at motor stator 1 accent and electronic terminal box 2 Di Kou connection places, with stator lead-out wire 4 corresponding positions, be provided with circular hole on the sealing gasket 3, lead-out wire 4 passes from circular hole.The YC112 motor lead should have 4, is connected respectively on the corresponding binding post of terminal box by the hole, places packing ring by technical specification, screws nut, installs connector cover.Sealing gasket 3 its cross sections of all edges are oval, and the centre is thinner, above corresponding position distribution 6 holes, wherein 4 holes are passed through for YC112 motor stator lead-out wire, middle 2 holes are link plate bolt hole, join brill at the bottom of the terminal box during screw hole assembling.
