Abstract
The invention discloses a reinforced spline shaft which comprises a shaft body, wherein a second spline, a third-order hollow part, a second-order hollow part, a first-order hollow part, a third spline and a first spline are arranged on the shaft body in sequence from top to bottom; a second tool withdrawal groove is formed between the second spline and the third-order hollow part; a third tool withdrawal groove is formed between the third spline and the second-order hollow part; a first tool withdrawal groove is formed between the first spline and the first-order hollow part; a reinforced sleeve is arranged on the second spline. The reinforced spline shaft is simple in structure and ingenious in design, so that parts sleeved on the spline shaft are precisely matched, the abrasion damage in a working process is greatly reduced, and the service life is prolonged; furthermore, the utilization rate of a material is increased, and the production cost is lowered.
Description
Technical field
The present invention relates to mechanical manufacturing field, relate in particular to a kind of splined shaft of strengthening.
Background technique
At present, splined shaft is as the component that transmit mechanical torque, and most applications requires the external component being sleeved on splined shaft to carry out precision positioning.But, the splined shaft of traditional domestic installation is solid construction, and its quality is larger, does not meet the light-weighted requirement of car load, and stock utilization is low, and cost of production is high, causes waste; Simultaneously, splined shaft is only external component to be carried out to rough location make it follow splined shaft action, make like this to occur very large wearing and tearing even directly causing splined shaft to damage between working procedure peripheral parts and splined shaft, be therefore necessary to make improvements.
Summary of the invention
For reducing complete vehicle quality, reduce production costs, the present invention proposes a kind of splined shaft.Problem to be solved by this invention is to provide splined shaft, makes to be sleeved on splined shaft, greatly reduces in working procedure.
In order to overcome the deficiency in above prior art, the invention provides one, to possess quality light, and cost is low, component precision-fit, the reinforcement splined shaft of the advantage such as wear damage is little, long working life.
The present invention takes following technological scheme to realize: a kind of splined shaft of strengthening, comprise axis body, on described axis body, be provided with successively from top to bottom the second spline, three rank are hollow, second order is hollow, single order is hollow, the 3rd spline and the first spline, between described the second spline and described three rank are hollow, be provided with the second tool withdrawal groove, between described the 3rd spline and described second order are hollow, be provided with the 3rd tool withdrawal groove, between described the first spline and described single order are hollow, be provided with the first tool withdrawal groove, above described the second spline, be provided with strengthening sleeve.
Between hollow and described two Jie in described three rank are hollow, be provided with stiffening plate.
Between hollow and described two Jie of described single order are hollow, be provided with stiffening plate.
The end face of described the first spline is provided with screw hole.
On the surface of described the first spline, the second spline, the 3rd spline, be equipped with quench-hardened case, the surface hardness of described quench-hardened case is HRC46, layer depth 1.96mm.
The present invention has following beneficial effect in sum: this product structure is simple, designs ingeniously, makes to be sleeved on the component precision-fit on splined shaft, greatly reduces the wear damage situation in working procedure, extends operating life.Meanwhile, improve stock utilization, reduced cost of production etc.
