Embodiment Construction

[0007] 1. Combine figure 1 Implementation: The bearing-type worm gear 1 is tightly positioned through the uniformly distributed screw holes 2 on the circumference of the worm gear and the required workbench set screws, and the bearing-type worm gear 1 is meshed with the arc-enveloping worm 4 and 11 without backlash 3 to ensure the transmission accuracy. The power shaft 5 passes through the adjustment sleeve and is bonded with the arc-enveloping worm 4, and the two worms of the arc-enveloping worm 4 and 11 are supported by the required housing. The synchronous pulley 7 is installed on the power shaft 5 and the power is transmitted to The synchronous pulley 9 on the shaft 10 ensures synchronous rotation through the adjustment mechanism to drive the arc surface enveloping worm 11, circular locking rings 12, 13 to adjust and lock the pulley 9 on the shaft 10;

Abstract

The invention provides a bearing type precise ball cambered surface envelope worm wheel spoke. For meeting the requirements of industrial equipment and machine tool building at present, the manufacturing of a wear-resisting worm wheel spoke which has a high requirement for precision and is large in the number of teeth in engagement and stable in rotation is badly needs to be realized; the bearing type precise ball cambered surface envelope worm wheel spoke utilizes a spiral cambered surface envelope worm wheel poke as a standard component, and adopts the mode that a spiral cambered surface block is cut out precisely in the face of worm wheel teeth, precision drilling is conducted to produce the ballistic curves evenly distributed around the cambered surface and exceeding the teeth face by a certain distance, installation ball steel balls are embedded on the face of the worm wheel teeth of a spiral cambered surface and meshed with a worm rod chambered surface of a spiral cambered surface envelope and rotate. Three to six teeth can be designed as required by the design, a multi-teeth chambered surface can be meshed with an envelope worm rod which can be single or double, and the transmission is stable.

Description

technical field [0001] This patent relates to the manufacture of mechanical equipment, key components in the field of machine tool manufacturing, deceleration, power transmission-bearing type precision spherical arc enveloped worm wheel spokes in industrial transformation. Background technique [0002] Ordinary worm meshing worm gear teeth number is 2 meshing, heavy-duty meshing transmission is easy to wear and is not suitable for current industrial equipment and machine tool manufacturing requirements; [0003] There is an urgent need to solve the manufacture of wear-resistant worm gears with high precision requirements, large number of meshing teeth, and stable transmission. The bearing-type precision spherical arc enveloped worm wheel spoke is based on the spiral arc enveloped worm wheel spoke, using ball steel balls as the enveloping effect between the tooth surface and the spiral arc enveloped worm, which has superior contact performance than cylindrical worm wheel spok...
