Embodiment

[0036] Example: such as figure 1 As shown, a double-row angular contact ball bearing includes a concentric inner ring 1 and an outer ring 2. The outer recess of the inner ring 1 is provided with two parallel inner grooves 11, and the inner recess of the outer ring 2 is provided with inner and inner grooves. The outer channel 21 opposite to the channel 11, the steel ball 41 that fits the outer channel 21 and the inner channel 11 and rotates between the inner ring 1 and the outer ring 2 is arranged, and the steel balls 41 of the same ring are held by a ring Frame 4 is fixed.

[0037] Such as figure 1 As shown, the inner ring 1 is provided with inner card slots 12 respectively recessed on both sides along its own thickness direction, and the outer ring 2 is provided with outer card slots 22 respectively recessed on both sides along its own thickness direction. The corresponding inner card slots 12 and A sealing ring 3 is arranged between the outer card slots 22 . The design of...

Abstract

The invention discloses a double-row angular contact ball bearing. The double-row angular contact ball bearing comprises an inner ring and an outer ring which are concentric; two parallel inner channels are formed in the outer side of the inner ring in a sunken mode; outer channels which are opposite to the inner channels are formed in the inner side of the outer ring in a sunken mode; steel ball attached to the outer channels and the inner channels to rotate are arranged between the inner ring and the outer ring; and the steel balls of the same ring are fixed through an annular cage. The double-row angular contact ball bearing has the advantages that by means of a sealing ring with an exquisite structure, the reasonability of the structure can be enhanced, and materials can be saved; and by means of machining equipment such as a grinding wheel and a guide wheel, the surface roughness of the inner channels and the surface roughness of the outer channels can be guaranteed to reach the standard, and meanwhile, the damage to the structural strength of the bearing can also be avoided.

Description

technical field [0001] The invention relates to a bearing used for an electromagnetic clutch, more specifically, it relates to a double-row angular contact ball bearing and its processing technology. Background technique [0002] When the engine is running normally, the belt pulley drives the cooling water pump to run. When the engine is just started, the temperature is not high, and the cooling water pump is turned on, which increases fuel consumption and shortens the life of the cooling water pump. [0003] The patent with the announcement number "CN202348708U", whose publication date is 20120725, discloses an engine electromagnetic clutch water pump, including: a battery, an electromagnetic clutch, a water pump, and a temperature control switch; the electromagnetic clutch includes: a gear I coil and a gear II coil ;The temperature control switch includes: I gear switch and II gear switch, I gear coil and I gear switch are connected in series to form I gear circuit; II gea...
