Abstract
The utility model relates to a peristaltic pump, in particular to a transmission device for a driver of the peristaltic pump. The transmission device comprises a timing belt pulley and a belt pulley fixing shaft, wherein straight knurlings are processed on the surface of the belt pulley fixing shaft; and the surface of the belt pulley fixing shaft is in tight contact fit with the hole surface of the central hole of the timing belt pulley. Compared with the conventional key connection, the connection between the timing belt pulley and the belt pulley fixing shaft of the transmission device for the driver of the peristaltic pump has the advantages that the strength and the reliability of the connection are improved greatly, and no connection clearance exists; moreover, the processing and the assembly of components are simpler and more convenient, and the rigidities of the components cannot be impacted.
Description
Technical field
The utility model relates to a kind of peristaltic pump, especially relates to a kind of transmission device of peristaltic pump driver.
Background technique
Peristaltic pump is a kind of displacement pump, is applied in usually in flowrate measuring tool, the medical apparatus, and it mainly is made up of pump head, driver and elastic hose.The driver of peristaltic pump adopts synchronous belt transmission device to come transfer of torque at present mostly, and synchronous belt transmission device is general main to be made up of synchronous pulley, synchronous band, belt wheel stationary axle and support.At present; Synchronous pulley adopts the key ways of connecting mostly with being connected of belt wheel stationary axle; The keyway Spielpassung of key on the belt wheel stationary axle and belt wheel center hole; The defective that this Placement exists is: the gap between key and the keyway can cause belt wheel inaccurate at the operation process medium speed, and produces noise; Simultaneously, the processing of key and keyway is also cumbersome, also can reduce the rigidity of belt wheel stationary axle.
The model utility content
The technical problem that the utility model will solve is: cause belt wheel inaccurate and produce the problem of noise at the operation process medium speed for there are matching gap in belt wheel in the synchronous belt transmission device that solves present peristaltic pump driver and belt wheel stationary axle because of key is connected, a kind of transmission device of peristaltic pump driver is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of transmission device of peristaltic pump driver; Include synchronous pulley, belt wheel stationary axle; Surface Machining at the belt wheel stationary axle has straight knurling, the tight contact matching of hole face of the surface of belt wheel stationary axle and the center hole of synchronous pulley.
The fit process of the center hole of synchronous pulley and belt wheel stationary axle realizes through press machine; In the fit process; Because the material hardness of synchronous pulley generally is lower than the material hardness of belt wheel stationary axle, so the straight knurling on belt wheel stationary axle surface certainly will embed in the hole face of center hole of synchronous pulley, thus synchronous pulley and the tight contact matching of belt wheel stationary axle; Extremely solid and reliable, there is not loosening gap fully.
The beneficial effect of the utility model is: the synchronous pulley of the transmission device of this peristaltic pump driver is compared with existing key Placement with the fit system that is connected of belt wheel stationary axle, and intensity, the reliability of connection improve greatly, and do not have joint gap fully; Simultaneously, the processing of parts is also simpler, convenient with assembling, can not influence the rigidity of parts.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation (synchronous pulley is analysed and observe) that the synchronous pulley of the utility model matches with the belt wheel stationary axle;
Among the figure: 1. synchronous pulley 2. belt wheel stationary axle 2-1. straight knurling
Embodiment
A kind of transmission device of peristaltic pump driver; As shown in Figure 1; It includes synchronous pulley 1, belt wheel stationary axle 2, straight knurling 2-1 is arranged, the tight contact matching of hole face of the center hole of the surface of belt wheel stationary axle 2 and synchronous pulley 1 in the surface Machining of belt wheel stationary axle 2.The fit process of the center hole of synchronous pulley 1 and belt wheel stationary axle 2 realizes through press machine; In the fit process; Because the material hardness of synchronous pulley 1 generally is lower than the material hardness of belt wheel stationary axle 2, so the straight knurling 2-1 on belt wheel stationary axle 2 surfaces certainly will embed in the hole face of center hole of synchronous pulley 1, thus synchronous pulley 1 and belt wheel stationary axle 2 tight contact matching; Extremely solid and reliable, there is not loosening gap fully.
Claims (1)
1. the transmission device of a peristaltic pump driver; Include synchronous pulley (1), belt wheel stationary axle (2); It is characterized in that: the surface Machining at belt wheel stationary axle (2) has straight knurling (2-1), the tight contact matching of hole face of the center hole of the surface of belt wheel stationary axle (2) and synchronous pulley (1).
