Abstract

The utility model provides a motor shaft structure with high yield strength, which comprises a rotating shaft and a bearing disc clamped outside the rotating shaft, wherein a rotor core positioned on one side of the bearing disc is arranged outside the rotating shaft, a limiting disc is sleeved outside the rotating shaft positioned on the other side of the bearing disc, and long bolts sleeved inside the bearing disc are sleeved inside the rotor core and the limiting disc. This motor shaft structure of high yield strength, through rotor core, spacing dish, the cooperation of stay bolt and nut is used, make the motor shaft can bear for other shaft segments through the stay bolt transmission to the bearing capacity that the installation shaft segment received, improve the whole bearing capacity of motor shaft, through the inside suit that bears the dish can bear other shaft segments to the centrifugal force differentiation that bears the dish and produce when rotating at the stay bolt, reduce the effort of being used in the installation shaft segment, and then because of local atress when avoiding the motor shaft to rotate, cause the motor shaft crooked.

Description

Motor shaft structure with high yield strength

Technical Field

The utility model particularly discloses a motor shaft structure with high yield strength.

Background

Rotor core in the motor is through adopting joint and slotted nut's mode with its fixed suit at the epaxial installation shaft section of motor, main bearing position when the motor shaft rotates is at rotor core's installation section, current partial motor shaft only leans on alone to install the shaft section and carry out fixed stay to rotor core, lead to the bearing capacity of motor shaft relatively poor, centrifugal force that produces when rotor core rotates only acts on the installation shaft section simultaneously, can cause the motor shaft crooked because of local atress when leading to the motor shaft to rotate, influence its life.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned defect among the prior art or not enough, this application aims at providing a motor shaft structure of high yield strength, including pivot and joint the dish that bears in the pivot outside, the outside of pivot is provided with and is located the rotor core who bears dish one side, the pivot is located the outside cover that bears the dish opposite side and is equipped with spacing dish, the inside cover of rotor core and spacing dish is equipped with the suit and is born the inside stay bolt of dish, the stay bolt extends the outside one end screw thread of rotor core and has cup jointed the nut, the inside screw thread of spacing dish has cup jointed the activity and has cup jointed the fixed cover in the stay bolt outside.

Preferably, one side of the rotor core, which is close to the bearing disc, is provided with reinforcing ribs distributed annularly.

Preferably, the number of the long bolts is six, and the six long bolts are annularly and equidistantly distributed in the limiting disc.

Preferably, one end of the fixing sleeve is provided with an external thread matched with the limiting disc, and the other end of the fixing sleeve is provided with a hexagonal notch.

Has the advantages that:

1. this motor shaft structure of high yield strength uses through the cooperation of rotor core, spacing dish, stay bolt and nut for the motor shaft can bear the weight of the bearing capacity that the installation shaft part received through stay bolt transmission for other shaft parts, improves the whole bearing capacity of motor shaft.

2. This motor shaft structure of high yield strength, through the inside suit that bears the dish at the stay bolt can bear other shaft segments for the centrifugal force differentiation that bears the dish and produce when rotating, reduce the effort of being used in the installation shaft segment, and then avoid the motor shaft to rotate the time because of local atress, cause the motor shaft crooked.
