Abstract

The utility model relates to an electric motor assembling welded clamping ring. The clamping ring is composed of a clamping plate with an iron core, which is punched and formed by a steel plate, a vent hole assembly, a side plate assembly, an upper observing hole assembly, a stop opening end ring, a lower observing hole assembly, a ground pin, a rib plate and lifting lug which are assembled. Each two assembling members are welded and fixed. Through the utility model improves the integral steel casting clamping ring of the existing motor into each assembling part which is formed by a steel plate in a punching way and welded together, the improved clamping ring of the motor overcomes the defects that the existing clamping ring has large machining allowance, complicated machining process, low efficiency, high reworking and repair welding rate, etc. which are caused by low casting precision.

Description

Motor erection welding formula trim ring

Technical field

The utility model relates to the particularly component parts of traction motor of motor, is specially a kind of erection welding formula trim ring of motor.

Background technology

Motor, support as the use for electric locomotive traction motor is made of forward and backward trim ring, laminated core and pull bar and gusset, its forward and backward trim ring all is the integral type cast steel structure of being made by casting technique, its shortcoming has: casting structure is bigger than complexity and size, can't implement hot investment casting, the casting tolerance is bigger, and machine-finish allowance is big, working (machining) efficiency is low, the repair welding rate of doing over again height.

Summary of the invention

The utility model solves existing motor integral type cast steel trim ring processing and the low problem of production efficiency, and a kind of erection welding formula trim ring of motor is provided.

The utility model is to adopt following technical scheme to realize: the erection welding formula trim ring of motor, this trim ring is assembled by the stamping forming pressing plate unshakable in one's determination of steel plate, ventilation hole assembling, side plate assembling, upper observation hole assembling, seam end ring, lower observation hole assembling, lower margin, gusset, hanger, and welding is fixing between each build-up member.This erection welding formula trim ring is compared with existing integral type cast steel structure trim ring, both are identical on overall structure, and, the shape and structure of the former each build-up member with and each other rigging position relation identical with the latter, both differences only are that the former is welded by each build-up member, and the latter is casting integrated moulding.But, trim ring is resolved into some, again each build-up member erection welding is constituted trim ring, on the basis of satisfying the motor bed-plate requirement by the stamping forming build-up member of steel plate, improve the machining property of trim ring greatly, improved the processing and the production efficiency of trim ring.

Though the utility model just will have the integral type cast steel trim ring of motor now and be improved to by stamping forming each the build-up member erection welding of steel plate and form, but it is big because of the low machine-finish allowance that causes of casting precision that the motor trim ring after improving has overcome existing trim ring, machining process is loaded down with trivial details, efficient is low, the high defective of the repair welding rate of doing over again, and technique effect is very obvious.

Embodiment

The erection welding formula trim ring of motor, this trim ring is assembled by the stamping forming pressing plate 1 unshakable in one's determination of steel plate, ventilation hole assembling 2, side plate assembling 3, upper observation hole assembling 4, seam end ring 5, lower observation hole assembling 6, lower margin 7, gusset 8, hanger 9, and welding is fixing between each build-up member.

This embodiment is an example with the electric locomotive traction motor full laminated frame, because its support adopts 6 utmost points, it is 12 square that iron core is correspondingly made, pressing plate unshakable in one's determination 1 is corresponding also make 12 square; Side plate assembling 3 is major parts of trim ring, and it links together pressing plate 1 unshakable in one's determination and seam end ring 5, and portion constitutes the trim ring inner chamber within it, and all erection welding is thereon for ventilation hole assembling 2, inspection hole assembling 4,6, gusset 8 and hanger.The side plate assembling has 5-6 component-assembled to be welded as required; Seam end ring 5 is used for installing the end cap of motor, comes the rotor portion of support motor.

Claims

1, a kind of erection welding formula trim ring of motor, it is characterized by: this trim ring is assembled by the stamping forming pressing plate unshakable in one's determination of steel plate (1), ventilation hole assembling (2), side plate assembling (3), upper observation hole assembling (4), seam end ring (5), lower observation hole assembling (6), lower margin (7), gusset (8), hanger (9), and welding is fixing between each build-up member.
