Document Type and Number:
WIPO Patent Application WO/2015/043461
Kind Code:
A1
Abstract:
A pulley, comprising a wheel hub (1), and a shock absorption wheel body (2) installed on the wheel hub (1); the wheel hub (1) comprises a first wheel hub body (11) and a second wheel hub body (12) both integrally formed from metal materials or plastic and mutually adaptive; the ends of the first wheel hub body (11) and the second wheel hub body (12) are respectively embedded into the shock absorption wheel body (2) from two sides thereof, the end of the first wheel hub body (11) being pressed against the end of the second wheel hub body (12), and both wheel hub bodies are fixed via bolts (3) to form a removable assembly, such that the shock absorption wheel body (2) is steadily sleeved on the wheel hub (1). The pulley has a simple structure, and is easy to assemble. When a wheel body is badly worn, the shock absorption wheel body (2) can be changed separately without changing the wheel hub (1), such that the wheel hub (1) can be recycled, thus avoiding waste, being more environmentally friendly, and enabling the entire pulley to be fully utilized to reduce costs.
