Abstract
The invention relates to a tensioning mechanism for preventing slippage in belt drive. The tensioning mechanism comprises a roller which is transversely crossed on an upper surface of a lower belt, wherein length of the roller is greater than width of the belt; two ends of the roller are sleeved in a spacer sleeve which is positioned at two ends of the roller through a bearing; a distance between an outer edge of the spacer sleeve and the surface of the roller is greater than the width of the belt; the spacer sleeve at two ends of the roller is hinged with or fixedly connected with top ends of two tension springs which are sleeved in two guide cylinders respectively; the bottom end of each tension spring is fixedly connected with or hinged with the bottom of the guide cylinder; and the guide cylinder and an upper belt which are symmetrically with respect to the middle section of the roller and fixedly arranged are positioned on two sides of the lower belt respectively. The tensioning mechanism has a simple structure, is convenient to mount and easy to detach, different springs can be replaced according to belt wheels with different specifications so as to meet different tensioning force requirements; and the tensioning force can be adjusted through adjusting the length of the tensioning spring, and slippage in belt drive is effectively prevented.
Description
Technical field
The present invention relates to a kind of mechanical transmission fields, specifically, relate to a kind of preventing with the tensioning mechanism that skids in the transmission process.
Background technique
The band transmission by flexibility band and belt wheel form be used for transmitting movement and the mechanical transmission of power; Be a kind of typical case and widely used mechanical drive mode; The band transmission has simple in structure, stable drive, can cushion absorbing, can be between big distance between shafts and multiaxis transferring power; And it is cheap, need not lubricate, safeguard characteristics such as easy, uses very extensively in the mechanical transmission in modern age.But owing in the band transmission process, skid easily, thereby cause transmission not steady, problem such as velocity ratio is inaccurate.In the existing technology, the band transmission often will be installed Idle wheel, and more complicated is installed, and is impracticable.
Summary of the invention
The present invention is directed to the problem that exists in the existing technology, it is a kind of simple in structure that purpose is to provide, and the tensioning mechanism in the band transmission of being convenient to install can effectively prevent with the skidding that takes place in the transmission.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of with the tensioning mechanism in the transmission; Said tensioning mechanism comprises the roller across the upper surface that places lower floor's band; The length of roller is greater than the width of band; The two ends of roller are contained in the interstage sleeve that is positioned at the roller two ends through bearing housing, and the outward edge of interstage sleeve and the distance of roller surface be greater than the thickness of band, and it is hinged with the top of two tension springs that are sleeved on two guide cylinders respectively or be fixedly connected to be arranged in the interstage sleeve at roller two ends; The bottom of tension spring is fixedly connected with the bottom of guide cylinder or is hinged, and guide cylinder and the epipelagic zone also fixedly laid about the middle section symmetry of roller lay respectively at the both sides that lower floor is with.
The outer surface of interstage sleeve is provided with ear bar or the auricle that has through hole.
The tension force of two tension springs is identical.
The present invention is simple in structure, is convenient to install, and is quick detachable; Can change different springs according to the belt wheel of different size,, also can regulate tension force through the length of regulating tension spring to adapt to different tension force requirements.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Embodiment: referring to Fig. 1.
A kind of with the tensioning mechanism in the transmission; Comprise that the length of roller 1 is greater than the width of band across the roller 1 of the upper surface that places lower floor's band, the two ends of roller 1 are contained in the interstage sleeve 2 that is positioned at roller 1 two ends through bearing housing; Like this; Band can drive roller and roll, and the distance on the outward edge of interstage sleeve 2 and roller 1 surface can guarantee like this that greater than the thickness of band band is constrained between two interstage sleeves all the time; Can not skid off; It is hinged with the top of the tension spring that is sleeved on two guide cylinders 43 or be fixedly connected with respectively to be arranged in the interstage sleeve 2 at roller two ends, and the bottom of tension spring 3 is fixedly connected with the bottom of guide cylinder 4 or is hinged, lays respectively at the both sides that lower floor is with about the middle section symmetry of roller 1 and the guide cylinder of fixedly laying 4 with epipelagic zone.
The effect of guide cylinder is the direction of restricted spring, avoids roller to take place to rock more greatly.
The tension force of the tension spring through two ends can make band be in tensioning state all the time, can not skid;
The outer surface of interstage sleeve 2 is provided with the ear bar 5 that has through hole, and present embodiment medi-spring upper end passes the back knotting from the through hole on the ear bar 5 and fixes, and also available auricle replaces ear bar, perhaps other known Placements.
In order to guarantee to be with stability of transmission, the tension force of two tension springs 3 is preferably roughly the same, the spring equal in length of stretching shape, and like this, we preferably adopt identical spring.
Claims (3)
1. one kind with the tensioning mechanism in the transmission; It is characterized in that: said tensioning mechanism comprises the roller (1) across the upper surface that places lower floor's band; The length of roller (1) is greater than the width of band; The two ends of roller (1) are contained in the interstage sleeve (2) that is positioned at roller (1) two ends through bearing housing; The distance on the outward edge of interstage sleeve (2) and roller (1) surface is greater than the thickness of band; It is hinged with the top of two tension springs (3) that are sleeved on two guide cylinders respectively or be fixedly connected to be arranged in the interstage sleeve (2) at roller (1) two ends, and the bottom of tension spring (3) is fixedly connected with the bottom of guide cylinder (4) or is hinged, lays respectively at the both sides that lower floor is with about the middle section symmetry of roller (1) and the guide cylinder of fixedly laying (4) with epipelagic zone.
2. the tensioning mechanism in the band transmission according to claim 1 is characterized in that: the outer surface of said interstage sleeve (2) is provided with ear bar (5) or the auricle that has through hole.
3. the tensioning mechanism in the band transmission according to claim 1 is characterized in that: the tension force of said two tension springs (3) is identical.
