Feature:
A universal joint is fitted between the driveshaft and the differential axle to transmit power through the axis of rotation. Perfectly smooth rotation is required, in order to handle the constantly changing angles of the rear axle caused by the vertical movement of uneven surfaces transmitted through the suspension system. In other words, a universal joint efficiently transmits power through both fixed and fluctuating angles. Moreover, since the universal joint is lightweight and compact with superior durability, it has proved to be a safe and positive product for power transfer in Automotive and Industrial applications. In recent years, we have been working to develop and produce the press type bearing which is aimed at improvement in intensity and durability and reduces cost further.
Structure:
A universal joint has four needle roller bearings that provide the strength and life which is most important and both the axes of the spider are inserted into two yokes. In the bearing, a seal is located to prevent dust, water, etc.from ingress and to prevent grease egress. For heavy duty vehicles with high torque transmission, such as large size vehicles and various industrial machine vehicles, a wing type (3 kinds: block, wing, delta) is used. Bolt-fastening mechanism and key-way are incorporated to the bearing and a precise circle is on its back. By receiving the torque through the key-way, even if a bolt is loosely tightened, the shearing stress does not apply to the bolt.
Qingdao New International Yuandong Mechanical & Electrical Parts Co., Ltd. Has modern office building and standard plant, which has big friction press machine as 1600 tons, high speed CNC forging hammer as 750 kgs, 1.5 tons & 2 tons, different friction press machines as 160 tons, 300 tons, 400 tons and 630 tons as total for sixteen forging production lines. There also has CNC and computer aided character carver in the molding workshop. The machining workshop has CNC and sixty pieces of numerical control machine tool. The factory can manufacture the big hot forging parts for train, railway, mine, electric power and other industries. Especially for the big quantity order of forging parts in suitable unit weight and volume, it can produce efficiently as one mold with several cavities in mass production. At present, the mature products are die forging auto parts for suspension system and steering system, other forging parts and lifting eye bolts and eye nuts. The lifting eye bolts and eye nuts have been sold to overseas, which had been won the high reputation by the customers of Japan, Germany and United States, especially for DIN580, DIN582, JIS1168, JIS1169 and ASTM standard eye bolts & eye nuts with different materials. Most customers are attracted by the good quality of the lifting eye bolts and eye nuts, which can satisfy the request of the size from M6 to M100. The product of eye bolt DIN444 is the most profession with the most complete sizes and most complete kinds of material in China, which the material includes usual carbon steel, high strength steel and stainless steel. The factory has own mold making workshop, heat treatment workshop, assembly & maintenance, testing and packing workshop in order to control the quality strictly. It also can purchase export products liability insurance as the customer's demand, which provides quality credit guarantee for customers.
Our company have professional Quality Management System IATF 16949: 2009 and ISO 9001: 2015. There also has the AD2000 certification.
