Description
Technical field
The utility model belongs to field of machining, relates to a kind of worm screw regulating mechanism, specifically a kind of worm screw backlash adjusting seat.
Background technique
Worm reducer plays coupling rotating speed and transmitting torque between prime mover and working machine or actuator, and worm screw backlash adjusting seat is indispensable critical elements in worm reducer, along with the passing of retarder operation time, each bearing of main frame will inevitably wear and tear, thus cause screw rod to produce axial float and radial displacement increasing, this change can allow between screw rod and screw rod, gap between screw rod and host shell and front/rear end changes; Common worm screw backlash adjusting seat is usually because machining accuracy is inadequate, hardness and wear resistance does not reach requirement, and accelerates the wearing and tearing of worm reducer, decreases the working life of worm reducer, not only affect workmanship, but also unnecessary economic loss may be caused.
Model utility content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of worm screw backlash adjusting seat, there is compact structure, volume is little, lightweight, easy for installation, simple to operate, wear-resistant, corrosion-resistant, the on-deformable feature of High Temperature High Pressure.
In order to solve above technical problem, the utility model provides a kind of worm screw backlash adjusting seat, comprise fixed hole, rack sleeve and straight flange, rack sleeve one end is provided with disc overlap outwardly, the marginal position of disc overlap is provided with one section of straight flange, on disc overlap, axisymmetric arranges at least two fixed holes, rack sleeve inside is provided with the empty cylinder of two-stage stepped cylindrical shape, diameter near the cylindrical empty cylinder of described disc overlap one end is greater than the diameter of another cylindrical empty cylinder, and the empty cylinder of large diameter cylinder type is provided with a circle with the cross section annulus of small-diameter circular cylindricality sky cylinder joint installs inside groove.
The technological scheme that the utility model limits further is:
Aforementioned disc overlap is provided with four fixed holes symmetrical between two, and fixed hole is counter sink.
Aforementioned disc overlap is also provided with four tapped holes, and four tapped holes are symmetrical between two.
The beneficial effects of the utility model are:
The utility model product, is provided with disc overlap in rack sleeve one end, and overlap is provided with fixed hole and tapped hole, not only can be used for fixed installation, and installation firmly, not easily loosens, and improves the stability of integral product; The edge of disc overlap is provided with one section of straight flange, not only can save the space of machine intimate, and when installing, when running into mounting point by domain place, the design of straight flange can be parallel to the ground, and the overall machine structure being is simple and clear, space Appropriate application; The empty cylinder of large diameter cylinder type is provided with a circle with the cross section annulus of the empty cylinder joint of small-diameter circular cylindricality and installs inside groove, and when installation main shaft, installation inside groove contributes to spindle nose to be fixed or Fastener in the middle part of main shaft is fixed, easy for installation; The utility model product with compact structure, volume are little, lightweight, easy for installation, simple to operate, wear-resistant, corrosion-resistant, have the on-deformable feature of High Temperature High Pressure.
Accompanying drawing explanation
Fig. 1 is the plan view of the utility model worm screw backlash adjusting seat;
Fig. 2 is the sectional view of the utility model worm screw backlash adjusting seat;
Wherein, 1-fixed hole, 2-tapped hole, 3-rack sleeve, 4-straight flange, 5-install inside groove.
Embodiment
Embodiment 1
The present embodiment provides a kind of worm screw backlash adjusting seat, structure as depicted in figs. 1 and 2, comprise fixed hole 1, rack sleeve 3 and straight flange 4, rack sleeve 3 one end is provided with disc overlap outwardly, the marginal position of disc overlap is provided with one section of straight flange 4, on disc overlap, axisymmetric arranges four fixed holes 1, rack sleeve 3 inside is provided with the empty cylinder of two-stage stepped cylindrical shape, diameter near the cylindrical empty cylinder of described disc overlap one end is greater than the diameter of another cylindrical empty cylinder, and the empty cylinder of large diameter cylinder type is provided with a circle with the cross section annulus of small-diameter circular cylindricality sky cylinder joint installs inside groove 5.
The technological scheme that the utility model limits further is:
Four fixed holes 1 on aforementioned disc overlap are symmetrical between two, and fixed hole 1 is counter sink.
Aforementioned disc overlap is also provided with four tapped holes 2, and four tapped holes 2 are symmetrical between two.
When using this product, by main shaft through rack sleeve 3, clamping fixing by installing inside groove 5, then by fixed hole 1 and tapped hole 2, overlap being fixedly mounted on fuselage or other links.
Above embodiment is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technological scheme basis is done, all falls within the utility model protection domain.
