Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pulleys, in particular to a novel connected pulley. Background Art
[0002] A pulley is a small wheel with a groove around its periphery that can rotate around an axis. A simple machine composed of a grooved disc that can rotate around a central axis and a flexible cable (rope, tape, steel cable, chain, etc.) that crosses the disc and can rotate around the central axis is called a pulley.
[0003] The existing pulleys have a small load-bearing capacity, uneven stress, are prone to degumming, and have a short service life of the product. Content of the Utility Model
[0004] The problem solved by the utility model is to provide a novel connected pulley, which solves the technical problems of the existing pulleys, such as small load-bearing capacity, uneven stress, prone to degumming, and short service life of the product.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A novel connected pulley includes a connecting conduit, a bearing sleeve, a bearing and a rubber-coated sleeve. The connecting conduit is symmetrically sleeved with two bearing sleeves in the middle, and both ends of the connecting conduit penetrate through the bearing sleeves and are connected to the inner hole of the bearing. The bearing is embedded in the bearing sleeve, and a rubber-coated sleeve is arranged on the outside of the bearing sleeve and the bearing.
[0007] Preferably, an embedding groove for embedding the bearing is arranged on the outside of the bearing sleeve.
[0008] Preferably, grooves are symmetrically arranged on the outside of the rubber-coated sleeve.
[0009] Preferably, the outer diameter of the connecting conduit is adapted to the inner diameter of the bearing.
[0010] The beneficial effects of the utility model are: enhancing the load-bearing capacity, balancing the stress, not being prone to degumming, and enhancing the service life of the product. Description of the Drawings
[0011] Figure 1 It is a schematic diagram of the overall structure of the utility model;
[0012] Figure 2 It is an exploded schematic diagram of the utility model.
[0013] Legend Explanation:
[0014] 1. Connecting conduit; 2. Bearing sleeve; 3. Bearing; 4. Rubber-coated sleeve; 5. Embedding groove; 6. Groove. Detailed Embodiment
[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] Specific examples are given below.
[0017] See also Figure 1 and Figure 2 A new type of one-piece pulley comprises a connecting conduit 1, a bearing sleeve 2, a bearing 3 and a rubber sleeve 4, the connecting conduit 1, two bearing sleeves 2 are symmetrically mounted in the middle of the connecting conduit 1, and both ends of the connecting conduit 1 pass through the bearing sleeve 2 and are connected to the inner hole of the bearing 3, grooves 6 are symmetrically opened on the outside of the rubber sleeve 4, the bearing 3 is embedded and installed in the bearing sleeve 2, and rubber sleeves 4 are arranged on the outside of the bearing sleeve 2 and the bearing 3.
[0018] The outer side of the bearing sleeve 2 is provided with an embedding groove 5 for embedding and installing the bearing 3.
[0019] Grooves 6 are symmetrically formed on the outer side of the rubber sleeve 4 .
[0020] The outer diameter of the connecting conduit 1 matches the inner diameter of the bearing 3 .
[0021] The two bearing sleeves 2 are sleeved in the middle position of the connecting conduit 1. The connecting conduit 1 passes through the bearing sleeves 2 and is connected to the bearing 3, so that it does not deviate, stabilizes the bearing 3, and slides silently.
[0022] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
