Abstract
The utility model discloses a buoyancy type belt tensioning device, which comprises a tensioning wheel, a pin shaft, a lever, a pin shaft, a support, a through rod, a nut, a buoyancy ball and a water tank, wherein the lever is arranged on the support through the pin, the upper-right portion of the lever is connected with the tensioning wheel through the pin shaft, the lower-left portion of the lever is connected with the through rod, the through rod is provided with a screw thread, and the screw thread is fixed on the lever through the nut. A long shaft section is arranged on the lower portion of the through rod, the buoyancy ball with a hole is penetrated on the long shaft section, and a long round hole is arranged on a buoyancy end of the lever, and is used to adjust the position of the buoyancy ball. Simultaneously, in consideration of handling of the water tank, two handles are arranged on the upper portion of the water tank, thereby being convenient for handling, and being further capable of being used for impact limit of the buoyancy end when a belt fractures. The buoyancy type belt tensioning device can adjust buoyancy moment, water plays the role of damping to the buoyancy ball when starting up and shutting down a belt transmission mechanism, therefore, the buoyancy type belt tensioning device has the effects of cushioning and absorbing energy.
Description
Technical field
The utility model relates to mechanical band and rope drive tension device, particularly a kind of buoyancy type belt stretcher.
Background technique
Band and rope drive are to rely on tension force to carry out work, and tension device is absolutely necessary.Existing belt transmission, be to be gravity type and mechanical type belt stretcher mostly, and the gravity type tensioning has the adaptivity of tension force.And the mechanical tensioning device belongs to the pressure tensioning, tension force should not be adjusted.Water plays damping function to float balls, when belt transmission in starting with while stopping, the effect of buoyancy type tension device tool buffering energy-absorbing.
The model utility content
The utility model provides a kind of buoyancy type belt stretcher, has superior shock-absorbing capacity.
A kind of buoyancy type belt stretcher that the utility model provides, its structure comprises: Idle wheel, bearing pin one, lever, bearing pin two, bearing, bar, nut, float balls and tank.Wherein crank throw shape lever is installed on bearing by bearing pin, and lever top links by bearing pin and Idle wheel.Bar is fixed on the lever left end by nut, and the bar foot is a major axis section, wears a float balls with holes.The lever left part has slotted hole, for the position of float balls, adjusts.Float balls sinks in the water of tank, forms buoyancy.Two handles are arranged at tank top, are convenient to the carrying of tank, the impact of lever while also preventing belt fracture.
The utility model is compared with existing same device, and its beneficial effect is: belt gear is when starting and parking, and this installs tool buffering energy-absorbing function, and buoyancy is apart from adjustable.
The accompanying drawing explanation
Fig. 1 is a kind of buoyancy type belt stretcher perspective view.。
Fig. 2 is lever schematic diagram in a kind of buoyancy type belt stretcher.
Fig. 3 is bar schematic diagram in a kind of buoyancy type belt stretcher.
Embodiment
As shown in FIG. 1 to 3, a kind of buoyancy type belt stretcher, be comprised of Idle wheel 1, bearing pin 1, lever 3, bearing pin 24, bearing 5, bar 6, nut 7, float balls 8 and tank 9.Float balls 8 and tank 9 materials are plastics, and lever 3, bar 6, nut 7 materials are aluminum alloy material.Crank throw shape lever 3 is installed on bearing 5 by bearing pin 4, and lever 3 tops link with Idle wheel 1 by bolt bearing pin 2, and bolt bearing pin 2 and Idle wheel 1 formation Spielpassung, flexible rotating during with 1 tensioning of assurance Idle wheel.Bar 6 heads have screw thread, and there is the shaft shoulder at middle part, by nut 7, are fixed on lever, and bar 6 foots are a major axis section, with float balls with holes 8, form Spielpassung.Lever 3 left parts have slotted hole, for the position of float balls 8, adjust.Float balls 8 sinks in the water of tank, forms buoyancy.Two handles are arranged at tank 9 tops, are convenient to the carrying of tank, the impact of lever 3 while also preventing belt fracture.
A kind of buoyancy type belt stretcher working procedure:
During belt tension, belt tension forms tensioning moment to bearing pin 4, and the buoyancy that float balls 8 is subject to forms buoyancy moment to bearing pin 4, and tensioning moment and buoyancy moment equate, completes tensioning.
