Abstract
The invention provides a connection structure of a crankshaft and a shock absorption belt wheel and belongs to the technical field of mechanical connection. The connection structure of the crankshaft and the shock absorption belt wheel comprises the crankshaft and the shock absorption belt wheel assembly, wherein the crankshaft and the shock absorption belt wheel assembly are provided with splines which are matched in appearance, and the crankshaft and the shock absorption belt wheel assembly are connected through the splines in a matched mode. According to the connection structure of the crankshaft and the shock absorption belt wheel, single-point stress of connection of the crankshaft and the shock absorption belt wheel assembly is changed to be multi-point stress, so that the friction area is enlarged, and damage, caused by woodruff key stress, to a shock absorption belt wheel after bolts are loosened is prevented. Meanwhile, the mature technology is adopted, and therefore the connection structure is suitable for being machined in a volume production mode.
Description
Technical field
The invention belongs to MACHINERY JOINT field, relate to the linkage structure of a kind of bent axle and damper pulley assembly.
Background technique
Damper pulley assembly is generally comprised of rubber, wheel hub and belt pulley, by woodruff key and damper pulley bolt, is pressed on the sprocket wheel of engine crankshaft front end, then by driving belt that engine power is passed to each annex of train.
Damper pulley assembly is that the friction torque providing by damper pulley bolt axis power is transmitted Engine torque at work, woodruff key itself is transmitting torque not, if the axle power of bolt is unreasonable or occur that larger error will cause damper pulley bolt looseness, after loosening under the continuous impact of woodruff key, damper pulley assembly wheel hub can break, thereby affects normal working of engine.
Summary of the invention
The object of the present invention is to provide a kind of bent axle and the damper pulley assembly linkage structure that can effectively avoid damper pulley assembly to be damaged when transmitting Engine torque.
In order to achieve the above object, solution of the present invention is:
Bent axle and a damper pulley assembly linkage structure, comprise bent axle and damper pulley assembly, the spline that described bent axle and damper pulley coordinate with profile, and connect by described spline fitted.
Spline on described damper pulley assembly is positioned at the inwall of the wheel of described damper pulley assembly, and the spline on described bent axle is positioned at described bent axle microcephaly's periphery.
The microcephaly of described bent axle has bent axle and damper pulley assembly linkage structure described in interior threaded hole and also comprises damper pulley assembly bolt, with the interior threaded hole of the microcephaly by described damper pulley assembly bolt and described bent axle be connected described bent axle and described damper pulley assembly.
Described bent axle and described damper pulley assembly are also located by woodruff key.
Owing to adopting such scheme, the invention has the beneficial effects as follows: bent axle of the present invention is connected bent axle with the linkage structure of damper pulley assembly single-point with damper pulley assembly is stressed, and to become multiple spot stressed, increased friction area, prevented after bolt looseness the stressed infringement that damper pulley is caused of woodruff key.Meanwhile, the present invention adopts ripe technique, is suitable for volume production processing.
Accompanying drawing explanation
Fig. 1 be in the embodiment of the present invention bent axle and damper pulley assembly linkage structure at bent axle and damper pulley assembly view when unassembled.
In accompanying drawing: 1, damper pulley assembly; 2, bent axle; 3, belt pulley internal spline; 4, crankshaft external spline.
Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
The present invention proposes a kind of bent axle and damper pulley assembly linkage structure, Figure 1 shows that its at bent axle and damper pulley assembly view when unassembled.This linkage structure comprises damper pulley assembly 1 and bent axle 2, wherein on the inwall of the interior wheel of damper pulley assembly 1 with belt pulley internal spline 3, the outer of the microcephaly of bent axle 1 placed with crankshaft external spline 4, belt pulley internal spline 3 and crankshaft external spline 4 cooperatively interact in shape, and damper pulley assembly 1 and bent axle 2 are connected by this belt pulley internal spline 3 and crankshaft external spline 4.
In the present embodiment, because crankshaft external spline 4 is positioned at the microcephaly's of bent axle 1 outside, therefore the microcephaly of bent axle 2 has interior threaded hole according to prior art, damper pulley assembly 1 is with damper pulley assembly bolt, and be connected damper pulley assembly 1 and the bent axle 2 of the interior threaded hole by damper pulley assembly bolt and bent axle microcephaly.Now, the axle power between damper pulley assembly 1 and bent axle 2 and the transmission of moment of torsion not only can be fixed against traditional damper pulley assembly bolt, can also transmit by the connecting body of belt pulley internal spline 3 and crankshaft external spline 4.Meanwhile, because the position of woodruff key between bent axle and damper pulley is not interfered in prior art in the position of spline joint in the present invention, so in the present embodiment, still adopt woodruff key to position bent axle 2 and damper pulley assembly 1.
Bent axle of the present invention is connected bent axle with damper pulley assembly linkage structure single-point with damper pulley assembly is stressed, and to become multiple spot stressed, increased friction area, prevented after bolt looseness the stressed infringement that damper pulley is caused of woodruff key.Meanwhile, the present invention adopts ripe technique, is suitable for volume production processing.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.Person skilled in the art obviously can easily make various modifications to these embodiments, and General Principle described herein is applied in other embodiments and needn't passes through performing creative labour.Therefore, the invention is not restricted to the embodiment here, those skilled in the art are according to announcement of the present invention, and not departing from the improvement that category of the present invention makes and revise all should be within protection scope of the present invention.
