return In July 2015, the company received an export order, and the customer required that the teeth of the slewing bearing products adopt the drum-shaped tooth structure. According to customer demand and product requirements, the research and development design department has customized new cutting tools and compiled sample processing technology, tracked the whole process of the production and testing of drum gear slewing support samples, and successfully developed a certain model of drum gear slewing support samples. The samples were tested by the testing center, and all the technical indicators met the requirements of the drawings. After the successful trial production of the samples, the small batch production was successfully realized with the cooperation of the business division, the heavy assembly business division and various departments of the research institute, and the orders were delivered as scheduled.
Drum gear slewing support is a product independently developed by our company. It was recognized as a provincial high-tech product in November 2013 because of its advantages such as high load bearing, long service life and hard to break teeth.
At present, most of the ring of slewing ring are straight or conical teeth, the phenomenon of broken teeth frequently occurs. Drum gear tooth thickness on both ends of the middle thick thin, allows for a larger angular displacement gear pair two axis, the angular displacement values for 3 ~ 6 times that of the straight tooth, large amount of angular displacement compensation, to improve the contact condition of gear meshing, can effectively eliminate or reduce the influence of the angular displacement, the tooth of small radial extrusion pressure by matching pinion, reduce broken tooth. The gear meshing pair of drum gear is designed by using the theory of equal strength, and the thickness reduction on one side is determined according to the needs of larger offset angular displacement and larger bearing capacity. Under the same specifications, materials, gear modulus, pressure Angle, displacement coefficient, etc. Due to the large amount of angular displacement compensation during gear meshing, the contact condition during gear meshing is improved.
Through the test and the customer use the verification, the drum tooth slewing ring because of its special tooth structure form, its transmission performance has the obvious advantage over the straight tooth, can better improve the broken tooth phenomenon, increase the bearing capacity of the slewing ring, prolong the life of the slewing ring.
