Abstract

The invention discloses an integral coupled fan clutch bearing, a main body structure of which is also applicable to a coupled bearing of an automobile water pump. The bearing comprises double-row rollers and single-row steel balls, and comprises an bearing outer ring, a mandrel, a steel ball retainer, a roller retainer and a seal ring, wherein a groove and a roller path are formed in the bearing outer ring for bearing rolling elements and guiding the rotation of the rolling elements, the rolling elements comprise steel balls and cylindrical rollers, the mandrel is axially inserted into the bearing outer ring, an inner groove is formed in the outer diameter of the mandrel and is used for bearing the steel balls and guiding rotation of the steel balls, an inner roller path is formed in the outer diameter of the mandrel and is used for bearing the cylindrical rollers, the steel ball retainer is arranged between the bearing outer ring and the mandrel, and is used for enabling the steel balls to be evenly distributed in the groove at intervals, the roller retainer adopts the structural design of a barrel-shaped structure and a spring collar, the spring collar is assembled on the bearing outer ring in a matching manner for preventing the cylindrical rollers from jumping out along the axial direction, and the seal ring is pressed into a seal groove in the end part of the bearing outer ring and keeps the stationary state with the bearing outer ring.

Description

technical field [0001] The invention relates to an integral shaft-connected fan clutch bearing, which belongs to the field of rolling contact bearings for rotary motion. Background technique [0002] Bearing structures in the prior art such as figure 1 As shown, the mandrel 1 is a multi-step structure, including figure 1 Thread M20 indicated by reference number 11 in, a first step 12 with a diameter of 30 mm, a second step 13 with a diameter of 40 mm, a large outer diameter 15 at the end with a diameter of 51 mm, and a large outer diameter 14 with a diameter of 80 mm [0003] The working conditions of the bearing are generally: [0004] 1. Working temperature -40°C--180°C; [0005] 2. The weight and load of the clutch: 1600N [0006] 3. The weight of the fan is 170N [0007] 4. The axial force is 1500N [0008] 5. Bearing rated speed: 2600r.p.m [0009] According to the outline structure diagram of the bearing and the bearing force and working conditions, the bearing ...
