The utility model discloses a next door of each through -hole all is equipped with the recess of an installation lubricating oil, and the through -hole produced in the work of enabling heat cooling and difficult rapidly takes place wearing and tearing, and three fixed internal thread hole is regular triangle and arranges on the body, and its atress is more even, and it is better to enable whole cylinder cap leakproofness.
Description
Technical field
The utility model relates to a kind of engineering goods, specifically the outer cylinder cap of a kind of computer embroidering machine reducing gear.
Background technique
, often there is following problem in using process in the outer cylinder cap of some the computer embroidering machine reducing gears on existing market: the interior threaded hole arrangement 1, as the outer cylinder cap of locking is uneven, causes outer cylinder cap sealing easily oil leakage not to occur by force; 2, outer shell covers and is not provided with enough grooves, and the heat that when therefore working, through hole upper bearing (metal) rotates can not carry out cooling and the step surface on through hole being made to wear and tear in time, and the lubrication of bearing can not be carried out in time; 3, the centre as main axis bearing installation during work is reinforced by not being set to, and easily ruptures.
Summary of the invention
The utility model provides the outer cylinder cap of a kind of computer embroidering machine reducing gear.
The purpose of this utility model solves the outer cylinder cap of more existing computer embroidering machine reducing gears, and the interior threaded hole arrangement as the outer cylinder cap of locking is uneven, causes outer cylinder cap sealing easily oil leakage not to occur by force; Outer shell covers and is not provided with enough grooves, and the heat that when therefore working, through hole upper bearing (metal) rotates can not carry out cooling and the step surface on through hole being made to wear and tear in time, and the lubrication of bearing can not be carried out in time; The centre of installing as main axis bearing during work is reinforced by not being set to, and the problem of fracture easily occurs.
The utility model solves the technological scheme that its technical problem adopts: the outer cylinder cap of a kind of computer embroidering machine reducing gear, comprise body, described body is set to rhombus camber line structure, three interior threaded holes are provided with above it, be set to interior threaded hole respectively, left inside tapped hole and right inside tapped hole, wherein the left side of left inside tapped hole and the right side of right inside tapped hole are respectively equipped with a first trapezoidal camber line groove and the second trapezoidal camber line groove, it is provided with a foursquare camber line groove between the two, a circular reinforced through hole is provided with between described upper interior threaded hole and foursquare camber line groove, First terrace is provided with below it, the left side of the described first trapezoidal camber line groove and the right side of the second trapezoidal camber line groove are respectively equipped with the first manhole and the second manhole, below both it is equipped with second step face and the 3rd step surface.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in the figure, the utility model comprises body 1, described body 1 is set to rhombus camber line structure, three interior threaded holes are provided with above it, be set to interior threaded hole 10 respectively, left inside tapped hole 8 and right inside tapped hole 2, wherein the left side of left inside tapped hole 8 and the right side of right inside tapped hole 2 are respectively equipped with one first trapezoidal camber line groove 7 and the second trapezoidal camber line groove 3, it is provided with a foursquare camber line groove 5 between the two, a circular reinforced through hole 9 is provided with between described upper interior threaded hole 10 and foursquare camber line groove 5, First terrace 9-1 is provided with below it, the left side of the described first trapezoidal camber line groove 7 and the right side of the second trapezoidal camber line groove 3 are respectively equipped with the first manhole 6 and the second manhole 4, below both it is equipped with second step face 6-1 and the 3rd step surface 4-1.
Described body 1 is set to bilateral symmetry, interior threaded hole 10 on it, the arrangement in equilateral triangle between left inside tapped hole 8 and right inside tapped hole 2 three, described first trapezoidal camber line groove 7 is identical with the second trapezoidal camber line groove 3 size structure, and the first described manhole 6 is identical with the size structure of the second manhole 4.
The side of each through hole of the present utility model is equipped with the groove that is installed lubricant oil, the heat that in work, through hole produces can be made to cool rapidly and not easily wear and tear, on body, three fixing interior threaded holes are equilateral triangle arrangement, it is stressed more even, and can make whole cylinder cap better tightness.
