Abstract

The utility model discloses a kind of roots blower automatic-type belt tensioning device, comprise base (1), vertical rod (5), support (4), spring (7), nut; Blower fan main frame (3) is installed on base (1) side, and vertical rod (5) is installed on base (1) opposite side; Support (4) one end and base (1) hinged, the other end is placed in vertical rod (5) by the bracket holes (6) of its upper setting; Support (4) below is held out against by the spring (7) be enclosed within vertical rod (5), and top is compressed by nut; Motor (2) is arranged on support (4), and drives blower fan main frame (3) by belt (10).When blower belt (10) occurs lax, support (4) and motor (2) auto-tensioning under gravity, thus the utility model has the advantage that can make belt auto-tensioning, not need to shut down adjustment.

Description

A kind of roots blower automatic-type belt tensioning device
Technical field
The utility model relates to a kind of roots blower automatic-type belt tensioning device.
Background technique
Roots blower in use belt there will be relaxation phenomenon due to the reason such as aging, affects blower fan air-supply.Now, often need to carry out shutdown adjustment to blower fan, affect normal productive process.
Model utility content
The utility model solves common roots blower in use belt, the problem that need to blower fan carry out shut down adjustment lax because the reason such as aging there will be.For this reason, the utility model provides a kind of roots blower automatic-type belt tensioning device, and it has makes belt auto-tensioning, do not need the advantage of shutting down adjustment.
To achieve these goals, the utility model adopts following technological scheme.
A kind of roots blower automatic-type belt tensioning device, comprises base, vertical rod, support, spring, nut; Blower fan main frame is installed on base side, and vertical rod is installed on base opposite side; Support one end and base hinged, the other end by it arrange bracket holes be placed in vertical rod; By the spring top clamping be enclosed within vertical rod below support, top is compressed by nut; Motor is rack-mount, and by belt drive blower fan main frame.
The hinged place of support and base also can be provided with fixing bolt, and fixing bolt can limit hinged place activity, prevents machine operation medium-height trestle from trembleing.
Vertical rod tiltable is installed on base, is convenient to support.
Nut can be T-nut, prevents support from deviating from from vertical rod better.
The beneficial effects of the utility model: when blower belt occurs lax, under gravity, automatically by tension on belt, simultaneously because the effect of spring makes the unlikely tension of belt, T-nut can prevent support from deviating from from vertical rod for support and motor.The utility model has can make belt auto-tensioning, do not need the advantage of shutting down adjustment.
