A spinning tension wheel, comprising a V-shaped groove rim (1) and a spoke (2) which are symmetrically arranged at the center. The V-shaped groove rim (1) and the spoke (2) are of a spinning integrated structure; the outer circumference of the spoke (2) is integrally connected to the outer bottom of the V-shaped groove rim (1); a bearing chamber is connected to the inside of the spoke (2); a bearing (3) is pressed in the bearing chamber; an upper stopper piece (4) and a lower stopper piece (5) are respectively provided on the upper side and the lower side of the spoke (2); and the upper stopper piece (4) and the lower stopper piece (5) are riveted by means of rivets (6). The tension wheel uses a spinning integrated structure, such that the production cost is reduced, the production efficiency is improved, the tension wheel is light in structure, high in assembly efficiency, high in rigidity, high in the surface smoothness of the V-shaped groove, compact in surface structure, and good in wear resistance, and prolonging of the service life of a belt is facilitated.

A projection-welding spinning tensioner includes a first spoke and a second spoke. The first spoke includes a first rim end, a first plate end and a first center plate end. The second spoke includes a second rim end, a second plate end and a second center plate end. The first and second spokes have a same structure and are arranged in a mirror-symmetrical manner. Several projection-welding points are disposed on opposing surfaces of the first plate end and/or the second plate end, the projection-welding points are annularly arranged at an interval, the projection-welding points are arranged in a form of a concentric circle to form a least two annular arrangements, welded fixation of the first plate end and the second plate end is completed through the projection-welding points. A cavity groove for holding a bearing is formed inside after the first and second center plate ends are docked.
