The characteristics of using a cone sleeve for the pulley:

① High centering accuracy improves rotation accuracy; ② The parts can easily move on the shaft before locking and positioning, which is equivalent to interference fit after locking; ③ The load is evenly distributed, without the need for shoulder positioning and less prone to axial movement; ④ Convenient installation, disassembly, and replacement, reducing maintenance costs; ⑤ Compact structure, capable of connecting non weldable materials, such as connecting to aluminum components; ⑥ Some cone sleeves have achieved standardized production and low cost.

Introduction to cone sleeve

Introduction to cone sleeve

The cone sleeve is tightly connected to the inner cone surface of the pulley, sprocket, and other transmission components through an 8-degree outer cone surface, greatly improving the centering accuracy of various transmission components. The size of the cone sleeve is designed according to the series standard. The keyway of its inner hole is processed according to ISO standards. Good universality and interchangeability, suitable for various occasions When the transmission component is operated for a long time, the inner hole and chain groove may be damaged. If the transmission component uses this type of cone sleeve, in this case, only the same specification of cone sleeve needs to be replaced to restore use. Therefore, it greatly improves the service life of transmission components, reduces maintenance costs, and saves time.

Cone sleeve classification

Cone sleeve classification

The cone sleeve is mainly divided into TB cone sleeve, QD cone sleeve, and STB cone sleeve. The holes where the cone sleeve matches the pulley are all half sided, and the two smooth holes on the cone sleeve and the two threaded holes on the pulley respectively form a complete hole. One threaded hole on the cone sleeve and one smooth hole on the pulley form a complete hole. During assembly, two screws are installed in the two threaded holes of the pulley. As the screws are continuously tightened in the threaded holes of the pulley, the thread action pushes the screws towards the small end of the tapered hole on the pulley. However, the two smooth holes on the conical sleeve are not fully machined through. Therefore, when the head of the screw presses against the bottom of the smooth hole, force is transmitted to the conical sleeve, and the conical sleeve moves relative to the small end of the tapered hole on the pulley, At this point, due to the taper, the cone sleeve continuously wraps around the shaft, which in turn acts on the cone sleeve and then on the pulley. In this way, the pulley, cone sleeve, and shaft are tightly assembled together.

Reference for Selection of European Standard Conical Sheave Pulleys

Reference for Selection of European Standard Conical Sheave Pulleys

When selecting the European standard cone sleeve pulley, the groove type and specific size need to be determined based on the data to find the corresponding specifications. There are fewer models of European standard cone sleeve pulleys, which can be divided into SPA, SPB, SPC, and SPZ types. At the same time, there are differences in groove size data with national and American standard pulleys. The specific data is as follows: The SPZ type pulley is 34 ° when the pulley diameter range is between 50mm and 80mm; 38 ° at 85mm~450mm; The SPA type pulley has a diameter range of 34 ° when the pulley is between 63mm and 118mm, and 38 ° when the pulley is between 125mm and 630mm; The SPB type pulley is 34 ° when the pulley diameter range is between 100mm and 190mm; 38 ° for 200mm to 315mm; The SPC type pulley has a diameter range of 34 ° for pulleys ranging from 200mm to 315mm, and 38 ° for pulleys ranging from 335mm to 125mm;
