Abstract
The utility model discloses a kind of wide combined type seven fenestra Rzeppa type retainer, comprise: support body, this support body has inner ball surface, outer spherical surface and uniform seven fenestras, inner ball surface and the concentricity setting of outer spherical surface, inner ball surface and outer spherical surface center overlap with the widthwise central of support body, the outer spherical surface Spielpassung of inner ball surface and seven corresponding raceway groove star sleeves; The inner ball surface Spielpassung of outer spherical surface and seven corresponding raceway groove outer races; This seven opening portions is circular, and remaining is oval, and the two ends of inner ball surface are symmetrical inner cylindrical surface.Described circle and ellipse are interspersed.The beneficial effects of the utility model are: steadily, reliably, flexibly, accurately can not only transmit motion and torque, and reasonable stress, and carrying torque is large, shock-resistant etc.
Description
Technical field
The utility model relates to a kind of constant velocity universal joint, namely plays clamping steel ball in seven channel ball cage type constant velocity universal joint, guides seven fenestra Rzeppa type retainers of corner.
Background technique
Seven fenestra Rzeppa type retainers of the seven channel ball cage type constant velocity universal joint of conventional construction, circumferentially the fenestra of seven deciles is generally rectangle.One is not through optimal design, this universal joint and retainer do not carry out the coupling of scientific and rational the best, bearing capacity is reduced, two is owing to being rectangular virtual aperture window, make the radial effective reinforcement of retainer wider than narrow, unbalance stress, damaged very easily in advance during use, three are fenestras is uniform, and star sleeve is difficult to assembling.
Model utility content
The utility model is according to above not enough, and provide a kind of wide combined type seven fenestra Rzeppa type retainer, the bearing capacity solving conventional construction seven fenestra Rzeppa type retainer is low, easily damaged in advance, the problem that assembling is inconvenient.
The technical solution of the utility model is:
A kind of wide combined type seven fenestra Rzeppa type retainer, comprise: support body, this support body has inner ball surface, outer spherical surface and uniform seven fenestras, inner ball surface and the concentricity setting of outer spherical surface, inner ball surface and outer spherical surface center overlap with the widthwise central of support body, the outer spherical surface Spielpassung of inner ball surface and seven corresponding raceway groove star sleeves; The inner ball surface Spielpassung of outer spherical surface and seven corresponding raceway groove outer races; This seven opening portions is circular, and remaining is oval, and the two ends of inner ball surface are symmetrical inner cylindrical surface.
In order to the wide conduct of area of contact and effective reinforcement improving internal and external spherical surfaces is preferred, described circle has 4-6, and correspondingly, described ellipse has 3-1.Devising again equal to respective steel bulb diameter sphere centre symmetry two planes in 4-6 circular fenestra and 1-3 rectangular virtual aperture window, for clamping steel ball, making whole seven channel ball cage type constant velocity universal joint realize the function of corner.
As preferably, described circle and ellipse are interspersed.
The beneficial effects of the utility model are: steadily, reliably, flexibly, accurately can not only transmit motion and torque, and reasonable stress, and carrying torque is large, shock-resistant etc.

Embodiment
Now by reference to the accompanying drawings the utility model is further described:
As shown in the figure, a kind of wide combined type seven fenestra Rzeppa type retainer, comprise: support body 1, this support body 1 has inner ball surface 11, outer spherical surface 12 and uniform seven fenestras, inner ball surface 11 and the concentricity setting of outer spherical surface 12, inner ball surface 11 and outer spherical surface 12 center overlap with the widthwise central 3 of support body, and this seven opening portions is circular 22, remaining is oval 21, and the two ends of inner ball surface 11 are symmetrical inner cylindrical surface 4.
Circular 22 have 4-6, and correspondingly, oval 21 have 3-1.
Circular 22 and oval 21 are interspersed.
