no. 1 example

[0034] The first embodiment: the fastening part 12 passing through the cooling oil hole of the rotor core is a metal card with a set length "匚" shape. First take the set length "L" shaped metal card and pass through each heat dissipation oil hole 10 in the multi-piece iron core stacked in layers of the cylinder, compact the multi-piece iron core tightly, and then put the "L" shaped metal card The part exposed from the heat dissipation oil hole 10 is bent against the wall of the heat dissipation oil hole to form a "匚" shaped metal clip to fasten the multi-piece iron core.

no. 2 example

[0035] Embodiment 2: The fastening part passing through the cooling oil hole of the rotor core may also be a hollow rivet with a predetermined length and a diameter slightly smaller than that of the cooling oil hole. Use a hollow rivet with a set length to pass through each heat dissipation oil hole 10 in the cylindrical multi-piece iron core, compact the multi-piece iron core, and then expose the hollow rivet from the heat dissipation oil hole 10 Rivet multiple iron cores tightly against the wall of the cooling oil hole.

no. 3 example

[0036] Embodiment 3: The fastening part passing through the heat dissipation oil hole of the rotor core may also be a hollow fastening bolt with a nut having a predetermined length and a diameter slightly smaller than the diameter of the heat dissipation oil hole. Use a hollow fastening bolt with a set length to pass through each cooling oil hole 10 in the cylindrical multi-piece iron core stacked in layers to lock the multi-piece iron core.

[0037] The motor rotor fastens the multi-piece iron cores of the rotor with fastening parts, removes the adhesive between the iron cores, improves the heat dissipation effect of the rotor iron cores, simplifies the assembly process, and improves the work efficiency.

Abstract

The invention relates to an iron core fastening structure for a rotor of a compressor motor. A plurality of pieces of iron cores are stacked in cylindrical shape to form an inner side used as a stator of a winding coil slot; a plurality of pieces of the iron cores are stacked in cylindrical shape to form an outer side used as the winding coil slot, and a rotor uniformly distributed with a plurality of heat radiating oil holes are arranged between the winding coil slot of the iron core and a driving shaft hole; and fastening elements pass though the rotor to fasten every heat radiating oil holes on a plurality of pieces of the iron cores stacked in cylindrical shape. The motor rotor fastens a plurality of pieces of the iron cores of the rotor via the fastening elements, and omits the adhesive between the iron cores, so as to improve the heat radiating effect of the iron cores, simplify the assembly process, and improve the work efficiency.

Description

technical field [0001] The invention belongs to a compressor motor technology, in particular to a compressor motor rotor iron core fastening structure using a fastening component to fasten the rotor iron core. Background technique [0002] Generally speaking, the compressor drives the drive shaft to rotate through the motor rotor to complete the compression process of the compressor for gas suction and discharge. [0003] FIG. 1 is a cross-sectional view of an example of a scroll compressor, and FIG. 2 is a schematic diagram of a conventional scroll compressor motor rotor core. [0004] Taking the structure of the scroll compressor as an example, the scroll compressor consists of the following parts. Filled with a certain amount of lubricating oil, the casing 1 connected to the steam inlet pipe SP and the exhaust pipe DP; the main base 2 and the auxiliary base 3 that play a fixed role are arranged at the upper and lower ends of the inside of the casing 1; The drive motor 4...
