Problems solved by technology

[0003] However, the premature failure of the deep groove ball bearing installed on the free end of the retarder braking device makes the vehicle have to be frequently overhauled and replaced with new bearings, which shortens the maintenance cycle of the vehicle and increase

Embodiment Construction

[0012] Specific embodiments of the present invention are described with reference to the accompanying drawings.

[0013] as attached figure 1 Shown: the parts of bearing of the present invention include: outer ring 1, inner ring 2, steel ball 3 and cage 4.

[0014] The contact angle α of the bearing is designed to be 40°, which is designed to enable the bearing to carry both radial load and large axial load at the same time.

[0015] as attached figure 2 As shown: widen the large end face 5 of the outer ring 1 as much as possible to increase the friction between the end face 5 and the clutch plate; the design of the upper step 6 avoids interference with the protruding end of the outer diameter surface 10 of the inner ring 2; the lower step The design of 8 avoids interference with the small head of cage 4; the design of outer ring 1 raceway with locking point 7 not only ensures the assembly requirements of the bearing, but also solves the problem of loose sets of the bearing...

Abstract

The invention discloses a special angular contact ball bearing for a liquid vortex flow retarder, comprising an outer ring (1), an inner ring (2), a steel ball (3) and a holder (4). The special angular contact ball bearing is characterized in that a bearing contact angle alpha is 40 DEG; the small end surface of the outer ring (1) is provided with an upper step (6) and a lower step (8), and a roller path of the outer ring (1) is provided with a lock dot (7); the end surface of the inner ring (2) is provided with an annular groove (9), the outside diameter surface (10) of the inner ring (2) can be used as a piston for sealing a cylinder, a step (11) is arranged above a roller path of the inner ring (2), and a lock dot (12) is arranged below the roller path of the inner ring (2); the holder (4) is led by the steel ball (3), and an angle (beta) of the holder (4) is 30 DEG. The invention has the advantages of compact structure, high rotation speed, long service life, good lubricating property, flexible rotation and steady operation, can simultaneously bear the jointed load of a radial direction and an axial direction and can especially bear heavier axial load. The special angular contact ball bearing can not be heated when urgently stopping at the speed of 2800 rotations/minute and has low manufacture cost and convenient installation.

Description

technical field [0001] The invention belongs to the application of bearing technology on large-scale special vehicles, and mainly relates to a special angular contact ball bearing for liquid eddy current retarders of large-scale special vehicles. Background technique [0002] At present, a new type of hydraulic eddy current retarder auxiliary braking system is adopted on large heavy-duty vehicles. It is characterized in that the rotor of the brake structure is respectively connected with the flange of the main shaft and the clutch through two sets of bearings, and the clutch controls the separation and combination of the flange of the main shaft and the finger structure. When the vehicle is not braking, the clutch assembly is in a disengaged state, and the retarder does not operate; only when the vehicle is braking, the clutch assembly is in a state of engagement, and the retarder operates to perform braking. The idling of the rotor of the retarder is avoided, the energy is...
