“…For no-joint wire rope that is closed into a ring, its production process is more complex and the cost is higher than for ordinary wire rope. No-joint wire rope is often used in transmission machinery; for example, the wire ropecontinuously variable transmission (WR-CVT) [1], which uses no-joint wire ropes instead of steel bands, is a typical application. A transmission system using no-joint wire rope is shown in Figure 3.…”

This paper takes a cross section of 6 × 7 + IWS wire rope as an example to complete the studies on a method of geometric modeling for no-joint wire rope and implementation of a 3D solid model. Frenet–Serret frame theory establishes three types of Frenet–Serret frame, which are double-helix winding straight line, single-helix winding arc, and double-helix winding arc, and it allows derivation of eight types of center line equation of wire. This paper has ascertained tangent condition of center lines of steel wires with the same name between arc and straight-line wire rope and closed condition of no-joint wire rope. It has been concluded that the length of steel wire must be an integer multiple of its lay pitch either in arc wire rope or in straight-line wire rope, and the name of wires in each wire rope must be consistent at the same time. Finally, using Pro/ENGINEER Wildfire 5.0 software generates a 3D solid model of no-joint wire rope.

“…This category of transmissions includes many different types, which due considerable applicability, have garnered attention from numerous researchers. Authors investigate, e.g., dynamic [1], stress distribution [2], power losses and efficiency [8,9] as well as heat transfer [10] in belt-type CVTs. Other studies concern geometric [3], kinematic [4] and performance [4,11] analyses of ball-type CVTs.…”

The aim of this paper is to assess the performance parameters of the cam-type pulse continuously variable transmission, which is a first attempt to investigate this issue in the presented manner. The transmission under investigation comprises two cams in cooperation with two units, each consisting of rollers connected to swing rods mounted on overrunning clutches. To accomplish this, a test stand was built and a detailed testing program was developed takes into consideration the influence of gear ratio, rotational speed, and load on the uniformity of motion and efficiency. Analysis of the obtained results leads to the conclusion that the tested transmission is particularly sensitive to changes in operating conditions, and its overall performance deteriorates as the reduction ratio increases. The best results were achieved with a load below the nominal one, at low rotational speeds and a low speed reduction. The transmission's structure design and operational principle result in significant power losses, as evidenced by an efficiency rating of less than 60%.

This functionality lead to optimum performance of engine and fuel economy [6][7][8][9] as make driving easier and more comfortable [10]. Moreover, applications of CVTs to wind power systems and mechanical press machine have been proposed [11,12].…”

Continues changing of gear ratio is accomplished by continuously variable transmission (CVT) gearboxes that perfectly matches the torque and rotational speed of engine with output conditions. Developing CVTs for better performance and make it more reliable is ongoing effort. Here we present new ratcheting CVT mechanism that is similar to cam based CVT but instead cam it has a free shaft. New CVT is totally mechanical, frictionless and self-adjustable. Its automatic feature makes it cost effective and reliable. Wide gear ratio is achievable easily and simple structure make it more feasible. In opposite to conventional belt-type or toroidal CVTs, this new CVT doesn't use friction force, so its energy transfer efficiency improved and made it durable.
