Abstract
The utility model relates to a generally-used pin row, which is characterized in that the sectional contour lines of the pin row and engagement of a towing wheel is formed by an arch line. The sectional contour line of the utility model is formed by a plurality of sectional arch lines, approaching the requirement of teeth contours of swaying lines and involutes, applicable to the towing wheel of the two tooth profile for general use of the pin rows and eliminate accidents cause due to wrong arrangement, also reduce the production cost of the pin row and the pin row seat. And the force bearing and the efficiency of transportation in mine are improved; the maintenance cost for important elements of a scraper conveyor is reduced.
Description
Technical field:
The utility model relates to the pin row of coal mine lower scraping plate conveyer traction usefulness, especially a kind of general pin row applicable to coalcutter cycloid and two kinds of traction wheels of involute.
Background technology:
After the external 143 cover fully-mechanized mining equipments of 1974 and twice introduction of China in 1978, coal machine travel mode is by there being chain haulage progressively to carry out the transition to hydraulic pressure chainless haulage and modern no chain electrical haulage, and the back two kinds of forms mainly traction wheel by coalcutter are meshed with the slat conveyer pin row and reach the purpose that coalcutter moves.At present, the traction wheel of coalcutter is divided into Cycloidal Wheel and involute is taken turns two kinds, pin row also is divided into the use that matches of two kinds of gerotor type pin row and involute-type pin rows and traction wheel, because coalcutter cycloid traction wheel and involute traction wheel are difficult to distinguish with profile, so happen occasionally, can cause shearer haulage wheel and the badly faulted accident of slat conveyer pin row this moment with wrong phenomenon.The pin row seat of pin row and its support simultaneously also because of pin row version difference, causes casting, forging mold various in style, manufacturing cost height, universalization seriation extending space deficiency.
Summary of the invention:
The purpose of this utility model is, overcomes the deficiencies in the prior art, designs a kind of general pin row that can be applicable to cycloid and two kinds of traction wheels of involute.
The realization the technical solution of the utility model is, a kind of general pin row is characterized in that, the cross section contour of pin row and traction wheel ingear partly are to be made of circular arc line.
Cross section contour of the present utility model adopts the segmentation circular arc line to constitute, and makes its requirement near cycloid and involute gear profile profile, goes for the traction wheel of these two kinds of profiles of tooth, has solved pin row general-duty problem.Thereby effectively eliminated the hidden danger that has an accident because of supporting mistake, greatly reduce the manufacturing cost of pin row and pin row seat simultaneously, the stressed situation of pin row also is improved, the rigidity of pin row, load-carrying capacity and service life are greatly improved, and have promoted efficient of transporting under the coal mine and the maintenance cost that reduces the crucial component of slat conveyer.
Description of drawings:
Number in the figure: 1 pin row, 2 traction wheels, 4 times circular arcs of circular arc on 3.
The specific embodiment:
The utility model is described in more detail below in conjunction with accompanying drawing:
The cross section contour of pin row 1 and traction wheel 2 ingears partly are to be made of circular arc line, and described circular arc line is at least two sections circular arcs that involute traction wheel and cycloid traction wheel profile of tooth are contained; The mate of pin row 1 cross section contour is last circular arc 3 and following circular arc 4 tangent formations, and last circular arc 3 radiuses are 65-72mm, and following circular arc 4 radiuses are 130-135mm.Two sections tangent arcs contain cycloid and involute, make shearer haulage wheel 2 with the engagement process of pin row 1 in based on rolling, can reduce sliding area, the enforcement of casting or Forging Technology when helping making simultaneously.For reducing the wearing and tearing that pin row 1 section slides and caused, pin row 1 can suitably be carried out surface hardening and be handled.
Claims (2)
1, a kind of general pin row is characterized in that, the cross section contour of pin row (1) and traction wheel (2) ingear partly are to be made of circular arc line.
2, general pin row according to claim 1 is characterized in that, described circular arc line is last circular arc (3) and the tangent formation of following circular arc (4), and last circular arc (3) radius is 65-72mm, and following circular arc (4) radius is 130-135mm.
