Abstract
The utility model discloses a kind of belt transmission automatic tensioning mechanism, it is characterized in that, synchronous pulley including tensioning apparatus and with runner motor connection, one end of tensioning apparatus is connected with tension pulley support, the other end is provided with tensioning wheel, and the outer rim of tensioning wheel is provided with circlip for shaft, circlip for hole.The extruding that the utility model passes through the rubber elastomer of strainer surrounding, auto-tensioning is realized in regulation with mechanical structure adjustment apertures, with easy for installation, operating space is small, automaticity is high, the advantages of adjustability is strong and workable, the features such as practicality is high.
Description
Technical field
The utility model is related to a kind of belt transmission automatic tensioning mechanism, and it is applied to the belt drive of rotary dehumidifier
Structure, can also be used in other fields with belt transmission.
Background technology
Belt transmission is, using a kind of machine driving widely, with simple in construction, to manufacture, install and easy to maintenance
The advantages of.But belt is elastomer, and elastic deformation can be produced after under tension effect.Relaxed due to plastic deformation, make just drawing
Power reduces, transmission capacity declines.So the transmission capacity in order to ensure belt, it is necessary to re-tensioning.
Tensioning apparatus common at present is divided into regular manual tension and auto-tensioning two ways.And auto-tensioning mode is normal
See two kinds of devices of pendulum auto-tensioning and spring auto-tensioning；The former is tensioning wheel is opened automatically by plumb-bob gravity
Tightly, the latter is to make tensioning wheel auto-tensioning by the pulling force of spring.Regular manual tension device is low with simple in construction and cost
The advantages of, but it is unfavorable for automated production；And pendulum automatic takeup is influenceed by the weight of pendulum and space, spring
Automatic takeup is gradually followed the string by the stretching of spring again.
The content of the invention
Problem to be solved in the utility model is that existing belt drive tensioner can not take into account automated production and steady
Qualitative the problem of.
In order to solve the above problems, the utility model provides a kind of belt transmission automatic tensioning mechanism, it is characterised in that
Synchronous pulley including tensioning apparatus and with runner motor connection, one end and the tension pulley support of tensioning apparatus are connected, separately
One end is provided with tensioning wheel, and the outer rim of tensioning wheel is provided with circlip for shaft, circlip for hole.
Preferably, the tensioning apparatus is connected by the tension wheel shaft in the middle of bearing and tensioning wheel.
Preferably, the synchronous pulley passes through belt motor shaft and runner motor connection.
Preferably, the end of the tensioning apparatus is provided with least two adjustment holes, and bearing is arranged in any one adjustment hole
In.
Preferably, the tension pulley support is provided with least two adjustment holes, and hex bolts is arranged in any one regulation
Kong Zhong.
The regulation that the utility model passes through the extruding of the rubber elastomer of strainer surrounding, and mechanical structure adjustment apertures
To realize auto-tensioning, with easy for installation, operating space is small, automaticity is high, the advantages of adjustability is strong and operability
By force, the features such as practicality is high.
Brief description of the drawings
A kind of structural representation for belt transmission automatic tensioning mechanism that Fig. 1 provides for the utility model；
Fig. 2 is the structural representation of tensioning apparatus.
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in figure 1, a kind of belt transmission automatic tensioning mechanism provided for the utility model, it includes tensioning apparatus 3
And synchronous pulley 17, synchronous pulley 17 is connected with runner motor 1.One end of tensioning apparatus 3 passes through hex bolts 11, plain washer
12nd, spring washer 13 is connected with tension pulley support 2, and the other end is provided with tensioning wheel 4, and the outer rim of tensioning wheel 4 is provided with axle bullet
Property back-up ring 7, circlip for hole 8.Tension pulley support 2 and the connecting hole of the upper end of runner motor 1 pass through hex bolts 14, plain washer
15 fix.Tensioning apparatus 3 is connected by bearing 6, hex-head nut 9, plain washer 10 with the tension wheel shaft 5 in the middle of tensioning wheel 4.Institute
Synchronous pulley 17 is stated to be connected with runner motor 1 by belt motor shaft.
As shown in Fig. 2 the end of tensioning apparatus 3 is provided with least two adjustment holes 31, bearing 6 is arranged in any one regulation
In hole 31.Tension pulley support 2 is provided with least two adjustment holes 30, and tensioning apparatus 3 passes through hex bolts 11, plain washer 12, bullet
Spring packing ring 13 is arranged in any one adjustment hole 30 fixed.
After all of above part installation, its operation principle is as follows：When runner motor 1 is rotated clockwise, drive
Synchronous pulley 17 is rotated, so as to drive belt 16 to rotate.At this moment tensioning apparatus 3 is in the presence of itself caoutchouc elasticity power so that
Tensioning wheel 4 is tightly pressed on belt.
Tensioning apparatus surrounding filling elasticity very strong rubber bodies, in the presence of belt pull and rubber bodies extruding, are compressed
Belt.When the elastic force of rubber bodies be not enough to compress belt when, can by the adjustment hole on fixed support and strainer,
Further to adjust the distance of tensioning, so as to compress belt again.
