Abstract
This invention relates to micro gap drive device, which comprises case and meshed gear and is characterized by spring parts with one end push other end along gear axis. This invention has the following advantages as a, micro gap between motor switch with high accuracy; b, simple process and matching for widely application.
Description
Technical field
The present invention relates to a kind of micro-gap transmission, be mainly used in speedup or gearing down.
Background technique
Because the industrial control automation degree is more and more higher, the gear reduction cabinet has that speed ratio is big, output torque is big, volume is little, the efficient advantages of higher.But common gear-box has 3 pairs or 4 pairs to participate in engagement because of gear simultaneously.Existing gear-box adopts the Placement of key or spline that axle is connected with gear usually, so a gear and an axle requirement on machining accuracy height, the technological requirement of considering processing and assembling must leave the gap, and in the process of transmission, when input end changes sense of rotation, promptly can be at output terminal because of the gapped driving angle error that produces.This class formation is " mechanical design handbook " of tool industry publishing house publication according to circumstances.
Summary of the invention
The object of the present invention is to provide a kind of micro-gap transmission, it can reduce gap between the part effectively to satisfy the requirement of high transmission accuracy.
The technological scheme that realizes the object of the invention is: a kind of micro-gap transmission comprises: casing and pitch wheel is characterized in that: resilient member is pushing away the shaft shoulder or the axle head of gear shaft to the other end from an axial end.
And gear shaft is connected with gear through the swelled coupling.
And, have the hole that allows bolt tightening instrument stretch in a side of casing.
And resilient member is a spring.
Perhaps, resilient member is a push action cylinder.
And, two helical gear oblique opposite on the jack shaft.
Advantage of the present invention is: 1. approach zero owing to can realize the gap, the backhaul gap is minimum during motor commutation (can reach zero.), thereby driving error is little, can satisfy the requirement of high transmission accuracy; 2. because direct geared is connected with axle through coupling, can saves coupling between motor and the input shaft, thereby can reduce axial dimension effectively, optimize the installation conditions of complete machine; 3. according to the technical program, improve existing transmission device with elastic part, swelled coupling etc., can be with better simply structure, lower cost, solve people and wish the difficult problem that solves for a long time; 4. manufacturing and assembly technology are simple, easy to utilize.
Description of drawings
Fig. 1 illustrates sectional view of the present invention on the whole.
Fig. 2 is the partial enlarged drawing at Figure 1A place.
Fig. 3 is the partial enlarged drawing at Figure 1B place.
Fig. 4 is the amplification view at Fig. 1 C-C place.
Embodiment
With reference to Fig. 1～Fig. 4, the invention will be further described below with reference to embodiment.Micro-gap transmission of the present invention comprises: casing 1 and pitch wheel 3,4,5,6, its distinctive feature is: resilient member 8 is pushing away the shaft shoulder or the axle head of gear shaft 7 to the other end from an axial end.
Preferably be separated with bearing 8.1 between the resilient member 8 and the shaft shoulder or the axle head.
Further technological scheme can be: gear shaft 7,7.1 is connected with gear 5,3 through swelled coupling 9,9.1.Specifically can be, respectively and between the gear shaft 7,7.1, bolt 10 will be positioned at taper tensioner circle 11 tensions of both sides at gear 5,3, under the squeezing action of its conical surface that cooperatively interacts and make gear 5,3 be anchored on one with gear shaft 7,7.1 respectively.
In when assembling,, can have in a side of casing 1 and to allow bolt tightening instrument stretch into hole 2 in the casing 1 for bolt tightening instrument can be gone into to tighten in the casing or unclamp bolt 10 by overhanging.
Described resilient member 8 can be a spring, also can be the thrust hydraulic jack.
Two helical gears 4,5 on the intermediate gear shaft oblique opposite, this will help offsetting when rotated axial play.
