Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: the prime mover with output element is installed on the framework soleplate, compressor with input element is installed on the compressor fixed plate, belt is transferring power between the output element of the input element of compressor and prime mover, described framework soleplate is provided with fixed support and the supporting screw that extends upward setting, described compressor fixed plate one side is hinged on the fixed support, its opposite side is limited on the supporting screw with being slidingly connected, described supporting screw is positioned at the compressor fixed plate and is provided with adjusting nut with the bottom, and described adjusting nut is bearing in the lower surface of compressor fixed plate directly or indirectly.By changing the position of adjusting nut on supporting screw, the inclination of adjustable compressor fixed plate, thereby changed the height at compressor input element axis place, make the distance between compressor input element and prime mover output element axis, promptly adjusted the rate of tension of belt, thereby make belt obtain required predetermined tension force, guarantee the working efficiency of compressor.The tensioning degree of periodicity or preoperation inspection belt, the tensioning degree by above-mentioned steps adjustment belt can make compressor be in good working order.
As preferably, described fixed support is provided with running shaft, described compressor fixed plate is provided with rotary sleeve, described rotary sleeve is set in that compressor fixed plate and fixed support are formed is hinged, guarantee that the hinged side height of compressor fixed plate is constant, the variable height that is connected a side by compressor with supporting screw makes the run-off the straight of compressor fixed plate, thereby reaches the purpose of adjusting the belt tension degree.
As preferably, be provided with axle sleeve between described compressor fixed plate lower surface and the adjusting nut, described axle sleeve upper end is against compressor fixed plate lower surface, and the axle sleeve lower end is against the adjusting nut upper end.Wherein, between compressor fixed plate lower surface and adjusting nut, axle sleeve is set, can be convenient to the rotation of adjusting nut, be convenient to operation.
As preferably, described supporting screw and compressor fixed plate joint and be segment with top, described segment is positioned at the compressor fixed plate and is provided with stop nut with top, prevents upwarping or beating in the compressor operating process of compressor fixed plate.
Fixed support can be fixedlyed connected with the framework soleplate split, also can adopt integrally formed, as preferably, described fixed support by framework soleplate upwards bending extend integrally formedly, simplified structure of the present utility model.
As preferably, the output element of described prime mover and the input element of compressor are the tooth form synchronous belt wheel, and described belt is the profile of tooth synchronous belt, can effectively guarantee the input element Synchronous Transmission of the output element and the compressor of prime mover, prevent to skid, guarantee the working efficiency of compressor.
As preferably, described adjusting nut comprises two coaxial nuts that are connected on the supporting screw, effectively guaranteed the supporting of adjusting nut to compressor fixed plate lower surface, improve stability, even one of them nut takes place under the situation of sliding tooth, the another one nut still can guarantee the supporting of adjusting nut to compressor fixed plate lower surface.
As preferably, be installed with set screw nut on the described framework soleplate, described supporting screw lower end is connected with set screw nut, is convenient to the dismounting between supporting screw and framework soleplate.
Therefore, but the utlity model has belt to adjusting to suitable tensioning degree, in the compressor operating process vibration less, characteristics such as working efficiency is stable, and working life is long.
