Abstract
The utility model relates to a belt tension device, which is characterized by including a base, an engine base and an elastic compression component, wherein the base is fixedly mounted at the lower part of a screw compressor main frame; the engine base is mounted at the bottom of a motor, and the right end of the engine base close to the screw compressor main frame is fixedly connected with the base in a hinging way; and the elastic compression component is arranged at the left end of the engine base, and is fixedly connected between the base and the engine base. The belt tension device provided by the utility model can effectively tension a belt.
Description
Technical field
The utility model relates to a kind of belt stretcher.
Background technique
The body of screw air compressor has a kind of belt driven type that is.Belt driven type is applicable to the compressor of 22KW left and right power, be by 2 belt pulleys of making by speed proportional with power via belt transmission.Belt needs good tensioning, to guarantee efficient driving between two belt pulleys.
Summary of the invention
The purpose of this utility model is to provide a kind of effectively belt stretcher of tightening belt.
The purpose of this utility model is achieved through the following technical solutions: a kind of belt stretcher is characterized in that: it comprise with the hard-wired base in helical lobe compressor host bottom, be installed on motor bottom and and the mutually close right-hand member of helical lobe compressor host and base be articulated and connected fixing support and be located at the left end of support and be fixedly connected on base and support between the elastic compression assembly.
Working principle of the present utility model is as follows: the motor wheel of being located on motor passes through belt transmission with the main wheel of being located on helical lobe compressor host, and belt makes and forms mutual traction action between motor wheel and main wheel; Because helical lobe compressor host is fixed on base, and support right-hand member and base are articulated and connected, under the effect of being implicative of each other, the left end of motor drives support upwarps, and the self gravitation effect of motor and support and elastic compression assembly are to the left end formation suppressing action of support, make motor wheel and main wheel keep mutually away from trend, make belt be in tensioning state.
Compared to prior art, the utility model has the advantage of: the pulling force that rationally utilizes belt with effective tightening belt, is saved manufacture cost with the interaction relationship between the downforce of the self gravitation of motor and support and elastic compression assembly.

Embodiment
Below in conjunction with Figure of description and embodiment, the utility model content is elaborated:
Be illustrated in figure 1 as embodiment's schematic diagram of a kind of belt stretcher that the utility model provides.
A kind of belt stretcher is characterized in that: it comprise with the helical lobe compressor host 1 hard-wired base 2 in bottom, be installed on motor 3 bottoms and and the mutually close right-hand member of helical lobe compressor host 2 and base 2 be articulated and connected fixing support 4 and be located at the left end of support 4 and be fixedly connected on base 2 and support 4 between the elastic compression assembly.
Connecting bolt 5-1, the top, lower end that described elastic compression assembly comprises that the lower end is articulated and connected with base 2 and support 4 is passed in the upper end is pressed in support 4 upper surfaces and is sheathed on the outer elastic pressed piece 5-2 of connecting bolt 5-1 and is threaded fixing with connecting bolt 5-1 and leans gland nut 5-3 in elastic pressed piece 5-2 upper end.By regulating gland nut 5-3, to guarantee elastic pressed piece 5-2, enough downforce are arranged, make belt 6 keep good tensioning state, make efficient driving between motor 3 and helical lobe compressor host 1.Described elastic pressed piece 5-2 can be spring.
Claims (2)
