Description
Technical field
The utility model relates to a kind of intensive of depositing data such as archives, the transmission device that particularly a kind of low noise is intensive.
Background technique
Intensive is used for industry and departments such as enterprise, public institution, bank, archives, library, museum, preserves various archive files.Under intensive the chassis travelling wheel is installed all, so that intensive is moved.The patent No. is 02287887.4, name is called, " intensive front and back wheels synchronous drive device " claims, " a kind of intensive front and back wheels synchronous drive device ... include frame and be placed on driving wheel on the ground rail; be fixed with two live axles in front and back of driving wheel; two live axles in these front and back separately by one group by chain be fixed on the driving mechanism that sprocket wheel constituted on the live axle; link to each other with the axis that is the support body bottom that links to each other with power mechanism and be placed in, the driving crop rotation on the live axle of front and back rotated synchronously ... make intensive shifting balance safety." but find that in practice two of front and back drive major axis because axle is gone up more than two bearings, cause the location.Particularly the bottom surface not at ordinary times, major axis will be powerful crooked by bearing.Therefore, transmission device exists noise big, rotates slack shortcoming.For remedying this deviation, adopt internal diameter the empty cover of front axle rear axle to be connected, to transmit power than front axle, connecting tube that the rear axle external diameter is big.But because of coaxality is not enough, the gap between connecting tube and the antero posterior axis constantly changes in rotation process, and still there is big noise in collision mutually between connecting tube and the antero posterior axis and rotates not smooth phenomenon.
Summary of the invention
The purpose of the utility model be to society disclose a kind of reasonable in design, noise is little, the planeness of bearing support installation base surface is required low, base is made the transmission device of intensive of more convenient low noise efficiently.
It is such that the utility model solves the technological scheme that above technical problem takes:
Intensive transmission device of a kind of low noise comprises chassis, power mechanism, driving mechanism; It is characterized in that, driving mechanism comprises, the active axis, two drive sprockets on the active axis, two driven sprockets of two drive sprocket correspondences, two front axles that drive respectively by two driven sprockets, travelling wheel on two front axles respectively, two rear axles, respectively with two rear axles and two two connecting tubes that front axle links together, two connecting tubes respectively with the fixator pins of forward and backward shaft connection place, the travelling wheel on two rear axles respectively, support axis, two front axles and two rear axles, be fixed on 5 pairs of bearings on the crosspiece of chassis; Two front axles are provided with groove with the joint that two rear axles are connected with connecting tube respectively, and groove is provided with " O " type elastic ring.
The technical measures of taking for the optimization technique scheme also comprise:
Described two connecting tube internal diameters are all than the big 4mm of external diameter of two front axles and two rear axles.
Described support axis, two front axles and two rear axles be the biserial bearing of tape spool bearing entad of 5 pairs of tape spool bearings.
Owing to taked above-mentioned technical measures, compared with prior art its advantage is:
Because two front axles are provided with groove with the joint that two rear axles are connected with connecting tube respectively, groove is provided with " O " type elastic ring, radial clearance variation when axle and connecting tube rotate is absorbed by O type elastic ring, avoid rigidity contact-impact between connecting tube and the antero posterior axis, overcome collision mutually between connecting tube and the antero posterior axis and formed big noise.
Because the biserial that 5 pairs of bearings of support axis, two front axles and two rear axles are tape spool bearings is the bearing of tape spool bearing entad, has reduced the planeness requirement to base upper bearing bracket installation base surface, it is more convenient efficient that base is made.And, further effectively reduce generating noise because the entad effect of the bearing of tape spool bearing of biserial makes axle rotate light and flexible more.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, intensive transmission device of a kind of low noise comprises chassis 12, power mechanism, driving mechanism; It is characterized in that, driving mechanism comprises, active axis 1, two drive sprockets 4 on the active axis, 9, two drive sprockets 4, two driven sprockets 4 ' of 9 correspondences, 9 ', by two driven sprockets 4 ', 9 ' respectively with chain 8,8 ' two front axles 5 that drive, 5 ', travelling wheel 3 on two front axles respectively, 3 ', two rear axles 10,10 ', respectively with two rear axles 10,10 ' and two front axle 5,5 ' two connecting tubes 7 that link together, 7 ', two connecting tubes 7,7 ' respectively with preceding, the fixator pins 6 of back shaft connection place, 6 ', respectively at two rear axles 10, travelling wheel 11 on 10 ', 11 ', support axis, two front axles and two rear axles, be fixed on 5 pairs of bearings 2 on 12 crosspieces of chassis; Two front axles 5,5 ' are provided with groove 13 with two rear axles 10, the 10 ' joint that is connected with connecting tube 7,7 ' respectively, and groove is provided with " O " type elastic ring 15.Two connecting tubes 7,7 ' internal diameter are all than two front axles 5,5 ' and two rear axle 10,10 ' the big 4mm of external diameter.Radial clearance variation when axle and connecting tube rotate is absorbed by O type elastic ring, avoid rigidity contact-impact between connecting tube and the antero posterior axis, overcome collision mutually between connecting tube and the antero posterior axis and formed big noise, reached the purpose of the utility model desire elimination noise.
Above-mentioned power mechanism is placed in intensive support body one side, can be manual power wheel or electric-powered the wheel, is connected with the sprocket wheel 16 of intensive transmission device by chain.This structure is very general, does not do detailed argumentation at this.
The biserial that 5 pairs of bearings 2 of described support axis, two front axles and two rear axles are tape spool bearings is the bearing of tape spool bearing entad.This class bearing has the performance of self-aligning.Can compensate automatically because the coaxiality error that the rich song of axle and housing distortion produce is applicable to that the supporting base hole can not guarantee in the parts of strict coaxality.This kind bearing mainly bears radial load, when bearing radial load, also can bear a spot of thrust load, and therefore, it is very suitable that the utility model is selected this kind bearing for use.
