Abstract
The utility model provides a pinion and rack transmission mechanism and relates to the filed of full-automatic glass cutting machines. The pinion and rack transmission mechanism comprises an eccentric bearing seat arranged on a base seat, a main shaft is arranged in the eccentric bearing seat through two deep groove ball bearings, and a spacer bush is arranged between the two deep groove ball bearings. A pinion is arranged on one end of the main shaft and matched with a rack, a circle-arc tooth synchronous pulley is arranged on the other side of the main shaft, and the circle-arc tooth synchronous pulley is connected with the main shaft through a self-centering type expansion sleeve. The eccentric bearing seat is adopted in the pinion and rack transmission mechanism, assembly gaps between the pinion and the rack can be adjusted by rotating the eccentric bearing seat, and therefore work efficiency is improved, production cost is reduced, and adjustment is benefited. The two deep groove ball bearings are used for transmission and the spacer bush is arranged between the two deep groove ball bearings, and therefore a guide section of the main shaft is increased, transmission accuracy of equipment is guaranteed, and product quality is improved greatly. The circle-arc tooth synchronous pulley is connected with the main shaft through the self-centering type expansion sleeve, and therefore the defects that the pinion and rack transmission mechanism is prone to looseness and does not benefit the adjustment by a key joint method in the past can be avoided.
Description
Technical field:
The utility model relates to the Full-automatic glass cutting field, relates in particular to a kind of rack and pinion drive mechanism of Full-automatic glass cutting.
Background technique:
Glass cutting machine is a kind of working machine that is exclusively used in glass processing and blanking.Along with China's rapid development of economy, the application of glass is more and more extensive, and the demand of corresponding glass cutting machine is also increasing year by year, and industry standard requires also more and more higher.Because the driving mechanism of glass cutting machine of the prior art all is single-bearing, connect with key, and adjust the top lower plug-type adjusting in gear rack gap, give to turn and join and adjusts and bring very large inconvenience, greatly reduce manufacturing efficiency and make troubles to later maintenance.
The model utility content:
Technical problem to be solved in the utility model is to overcome the defective of prior art, and a kind of rack and pinion drive mechanism of high working efficiency is provided.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of rack and pinion drive mechanism, it is characterized in that: comprise the eccentric bearing block that is installed on the mounting base, come the gap of regulating tooth wheel and rack by the rotating eccentricity bearing support, by two deep groove ball bearings main shaft is installed in the eccentric bearing block, be added with spacer in the middle of two deep groove ball bearings, one end of described main shaft is installed gear, wheel and rack cooperates, described main shaft opposite side is installed the arc tooth synchronous belt wheel, arc tooth synchronous belt is taken turns with main shaft by certainly medium-sized expansion sleeve being connected, guaranteed assembly quality, improved greatly the adjustment mode of arc tooth synchronous belt wheel on X-axis and Y-axis, brought convenience for later maintenance and dismounting.
Described eccentric bearing block one end is provided with the bearing limited step, and the other end arranges the eccentric bearing block gland, and deep groove ball bearing is fixed in the eccentric bearing block firmly.
The beneficial effects of the utility model:
1. adopt eccentric bearing block, come the fit up gap of regulating tooth wheel and rack by the rotating eccentricity bearing support, heightened working efficiency, reduced cost of production, more be beneficial to adjustment.
2. the utility model passes through two deep groove ball bearing transmissions, and is added with a spacer in the middle of two deep groove ball bearings, has increased the guide section of main shaft, has guaranteed the transmission accuracy of equipment, has improved widely quality of product.
3. the utility model arc tooth synchronous belt wheel is connected medium-sized expansion sleeve by oneself with main shaft, avoids former employing key Placement existence easily to become flexible, be unfavorable for the defective adjusted.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of rack and pinion drive mechanism, comprise the eccentric bearing block 3 that is installed on the mounting base 9, come the gap of adjusting gear 6 and tooth bar 7 by rotating eccentricity bearing support 3, by two deep groove ball bearings 4 main shaft 5 is installed in the eccentric bearing block 3, be added with spacer 8 in the middle of two deep groove ball bearings 4, one end of main shaft 5 is installed gear 6, gear 6 cooperates with tooth bar 7, main shaft 5 opposite sides are installed arc tooth synchronous belt wheel 10, arc tooth synchronous belt wheel 10 is connected medium-sized expansion sleeve 1 by oneself with main shaft 5, has guaranteed assembly quality, has improved greatly the adjustment mode of arc tooth synchronous belt wheel 10 on X-axis and Y-axis, bring convenience for later maintenance and dismounting, eccentric bearing block 3 one ends are provided with the bearing limited step, and the other end arranges eccentric bearing block gland 2, and deep groove ball bearing 4 is fixed in the eccentric bearing block 3 firmly.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. rack and pinion drive mechanism, it is characterized in that: comprise the eccentric bearing block that is installed on the mounting base, by two deep groove ball bearings main shaft is installed in the eccentric bearing block, be added with spacer in the middle of two deep groove ball bearings, one end of described main shaft is installed gear, wheel and rack cooperates, and described main shaft opposite side is installed the arc tooth synchronous belt wheel, and arc tooth synchronous belt is taken turns with main shaft by certainly medium-sized expansion sleeve being connected.
