Slewing Ring Bearing With External Gear is with gear on the external ring, it is processed by a gear shaping machine. Customer can prefer the gear hardening treatment or not according to the working condition, if it need high load and press, we advise to do hardening treatment. Due to the gear is on the outer ring, it can maximized the use of the limited space of the slewing ring and it is very easy to check the gear engagement and failure diagnosis. Another advantage is due to the large pitch circle diameter of the outer gear, it can be better to achieve a larger transmission ratio and greatly reduce the circuar force and torque to the related pinion.
1.What’s kinds of teeth type for slewing bearing rings with external gear we often make?
Our company provided you with standard teeth, British standard teeth, stub teeth, helical teeth, worm gear, synchronous pulley and sprocket.
2.What’s the module of tooth for slewing bearing with external gear we often make?
For common standard metric model tooth and British standard DP1.75、DP2、DP2.5、DP3、DP3.5、DP4、DP5、DP6、DP8、DP16、DP5/7、DP3/4、DP4/5, we all can make.
The precision of tooth machining is 8 grade,9 grade,10 grade.
3.Tooth heat treatment of slewing bearing with external gears
Tooth heat treatment of slewing bearing with external gear includes tooth surface quenching, tooth surface &tooth root quenching and full tooth quenching.
Slewing Ring Bearing With External Gear Features and Benefits
our procedure technology of slewing bearing with internal gear and slewing bearing with external gear is very mature for the processing of teeth, especially the heat treatment of teeth.
The quenching of the teeth includes surface quenching, root tooth & surface quenching and full quenching.
The surface hardness of the quenched part is 50-60HRC, and the depth of the effective hardened layer must also meet the corresponding requirements according to the size of the teeth, and there should be no cracks on the surface of the tooth after hardening treatment.
We have been inspecting each set of products in strict accordance with the customer drawing requirements.
