Abstract

The utility model discloses a rotor blade with chamfer, including the rotor, the outside of rotor is equipped with a plurality of blade, characterized by: the outer ends of the upper side surface and the lower side surface of the blade are provided with chamfers. The utility model discloses a rotor blade with chamfer, its direct effect lies in: the top of each blade is provided with a tiny chamfer angle of 1.5 multiplied by 15 degrees, so that the friction reducing effect is achieved, and the rotor is prevented from being stressed and abraded in the working process, and the material falling and other failures are prevented. The indirect effect is that: the small chamfer angle can avoid the phenomena of collision damage, burrs, bulges and the like at the circumferential position of the rotor.

Description

Rotor blade with chamfer

Technical Field

The utility model relates to a camshaft phaser technical field, in particular to rotor blade with chamfer.

Background

Chinese patent application No. CN201610788904.4 discloses a phaser rotor structure and a method for manufacturing the same, the phaser rotor structure includes a phaser rotor (1), and a plurality of dents (12) are disposed on a cam shaft fitting surface (11) on the phaser rotor (1). Because set up a plurality of indents on with the camshaft binding face, make this increase with the roughness of camshaft binding face correspondingly, when phaser rotor and camshaft work of mutually supporting, can increase effectively the friction torque with camshaft binding face on the phaser rotor, prevent to take place the phenomenon of skidding between phaser rotor and the camshaft, show the location reliability who has improved between phaser and the camshaft, avoided piston and valve to collide with each other effectively. The dents can be processed by a laser marking method, and the non-contact processing method is easier to implement, has higher processing efficiency and lower implementation cost compared with the traditional mechanical processing method.

The above prior art is the structure of simple current rotor, but the structural design of its rotor is very simple, and in actual work, the end of rotor can produce collision and bump damage to influence the normal work of camshaft phaser.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a rotor blade with chamfer, its top design that has every blade has small chamfer 1.5 x 15, plays the antifriction effect, prevents that the rotor from atress wearing and tearing in the course of the work, produces inefficacy such as material drops, and small chamfer can avoid the advantage that phenomenon such as the bruise, burr, swell of rotor circumference position produced.

The above technical purpose of the present invention can be achieved by the following technical solutions:

rotor blade with chamfer, including the rotor, the outside of rotor is equipped with a plurality of blade, characterized by: the outer ends of the upper side surface and the lower side surface of the blade are provided with chamfers.

Through the technical scheme, the method further comprises the following steps: the chamfer angle is 10-20 degrees.

Through the technical scheme, the method further comprises the following steps: the chamfer angle is 15 degrees.

Through the technical scheme, the method further comprises the following steps: the outer ends of the blades are provided with sealing grooves, and the angles of chamfers on the blades on two sides of each sealing groove are the same.

Through the technical scheme, the method further comprises the following steps: the length of the chamfer is less than one tenth of the blade length.

Through the technical scheme, the method further comprises the following steps: the left side and the right side of the outer end of the blade are provided with arc edges.

To sum up, the utility model discloses the beneficial effect who contrasts in prior art does:

1. the utility model discloses a rotor blade with chamfer, its direct effect lies in: the top of each blade is provided with a tiny chamfer angle of 1.5 multiplied by 15 degrees, so that the friction reducing effect is achieved, and the rotor is prevented from being stressed and abraded in the working process, and the material falling and other failures are prevented.

2. The utility model discloses a rotor blade with chamfer, its indirect effect lies in: the small chamfer angle can avoid the phenomena of collision damage, burrs, bulges and the like at the circumferential position of the rotor.
