Abstract
The utility model belongs to the technical field of the round -link chain transmission, concretely relates to round -link chain direction wheelset has solved the round -link chain and has twistd reverse and take off the groove problem. It includes four leading wheels, and two leading wheels of round -link chain are a set of and same level setting in the restraint, and restraint two leading wheels of round -link chain down be a set of and same level setting, and two leading wheels of round -link chain homonymy are installed on the same axis, and the radius of circle is less than 0.9 times of round -link chain silk footpath at the bottom of the leading wheel, and end circle both wings level, the interval of both wings are greater than directly 1.1 times of round -link chain silk. The utility model has following beneficial effects: : 1, when changing round -link chain transmission orientation and movement track, prevent that the round -link chain from reversing, 2, at vertical direction restraint round -link chain movement track.
Description
Technical field
The utility model belongs to the technical field of chain transmission, and in particular to a kind of round-link chain directive wheel group.
Background technology
Round-link chain is used to be driven, and used as guidance set, pulley is the transmission side for changing power to existing general selection pulley
To or change the movement locus of fairlead, pulley bottom garden radius is typically directed to 1.1 times of thing, and pulley wing side inclines 20-
30°.This primarily radial stress of pulley, can make to be directed to the de- groove of thing when both wings stress is excessive, when being oriented to round-link chain, can make
Round-link chain reverses or takes off groove.
The content of the invention
The utility model reverses and takes off groove to solve the problems, such as round-link chain, there is provided a kind of round-link chain directive wheel.
The utility model adopts the following technical scheme that realization：
A kind of round-link chain directive wheel group, including four directive wheels, two directive wheels of round-link chain are for one group and same in constraint
One is horizontally disposed with, and two directive wheels of the lower round-link chain of constraint are that one group and same level are set, two guiding of round-link chain homonymy
Wheel is arranged on same axis, and less than or equal to 0.9 times of round-link chain string diameter, both wings level, both wings are justified in bottom to directive wheel bottom radius of circle
Spacing more than or equal to 1.1 times of round-link chain string diameter.
The utility model has the advantages that：
1st, while round-link chain direction of transfer and movement locus is changed, prevent round-link chain from reversing；
2nd, round-link chain movement locus is constrained in vertical direction.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 directive wheels install profile,
In figure：Square tube in the middle of 1- axles, 2- bearings, 3- directive wheels, 4- oil sealings, 5- jam plates, 6- round-link chains, 7- gun carriages frame.
Specific embodiment
Specific embodiment of the invention is described further with reference to accompanying drawing.
Round-link chain directive wheel group, including four directive wheels, two directive wheels of round-link chain are one group and same water in constraint
Flat to set, two directive wheels of the lower round-link chain of constraint are that one group and same level are set, two directive wheels peace of round-link chain homonymy
On same axis, directive wheel bottom radius of circle less than or equal to 0.9 times of round-link chain string diameter, justify between both wings level, both wings by bottom
Away from 1.1 times more than or equal to round-link chain string diameter.
Embodiment 1：Colliery tractor trailer train is applied to, tractor trailer train includes some gun carriages for once connecting, and gun carriage length is
2a。
As shown in figure 1, round-link chain directive wheel group by：The groups such as axle 1, bearing 2, directive wheel 3, oil sealing 4, jam plate 5, round-link chain 6
Into.
Directive wheel 4 has 4, constrains two groups of directive wheels 3 of upper and lower round-link chain for one group and up and down respectively in same level,
The directive wheel of round-link chain homonymy is installed on a shaft.Four groups of directive wheels symmetrically installed in tractor trailer train gun carriage center
In the middle of gun carriage frame in square tube 7, the Y-axis of same round-link chain directive wheel group is determined away from by round-link chain width, round-link chain is smoothly led to
Cross, the wheel base of adjacent rings chain directive wheel group is a（The 1/2 of gun carriage length）.Round-link chain described in the utility model is oriented to
Wheel group controls round-link chain 6, and one is that limitation round-link chain 6 is off-center, and two is that limitation round-link chain 6 is reversed（Because round-link chain 6 manufactures essence
When the accumulated error of degree makes its stress, vertical ring does not stand, and flat ring is uneven）, three is that limitation round-link chain 6 drifts about upwards in concave arc-shaped section.Lead
Be less than or equal to the string diameter of round-link chain 6 to 3 bottom radius of circles of wheel, leave enough gaps, bottom circle both wings level, the spacing of both wings more than etc.
In 1.1 times of round-link chain string diameter.
As shown in Fig. 2 fixing jam plate in square tube 7 in the middle of gun carriage frame, jam plate is embedded on axle, realizes the positioning of axle.
