Abstract

The utility model relates to an egg-turning two-stage reducer of a hatching machine, comprising a small worm, a small worm gear, a big worm and a big worm gear. The small worm is meshed with the big worm; the small worm gear is meshed with the big worm gear; the small worm gear is arranged on an output shaft; the small worm and the output shaft are arranged on a case body; the big worm and the big worm gear are arranged on a support base; and one end of the output shaft is connected with the big worm. The utility model is simple in structure and convenient to process, assemble and install and has low manufacturing cost.

Description

The incubator egg-turning double reduction gear

Technical field

The utility model relates to a kind of decelerator, the egg-turning double reduction gear on specifically a kind of hatch machine.

Background technology

The reducing gear that original incubator egg-turning is used has two decelerators, in wherein case top, an another of being located at hatch machine is located at the bottom of the case, is connected by a major axis that is extended through at the bottom of the case by the case top between the output shaft of two decelerators and power shaft, the decelerator that is positioned at the case top passes through the decelerator at the bottom of the major axis transmission case after by the motor transmission again.This reducing gear exists the deficiency that physical dimension is big, cost is high, installation is complicated.For overcoming above-mentioned deficiency, existing a kind of incubator egg-turning has adopted following structure with double reduction gear: a small gear and small worm engagement, one big worm gear and a big worm engaging, small gear is contained on the big worm screw, and small gear, small worm, big worm gear, big worm screw are contained on the bearing.Above-mentioned existing double reduction gear is compared with original, structurally comparatively compact, but because small gear directly is contained on the big worm screw and small gear, small worm, big worm gear, big worm screw are contained on the bearing, its globality is higher, to processing accuracy and the assembling accuracy requirement also higher, therefore, existing this incubator egg-turning exists the deficiency that processing cost is higher, assembling is inconvenient with double reduction gear.

The utility model content

The emerging purpose of this practicality is to provide a kind of incubator egg-turning double reduction gear, its handling ease, easy to assembly.

For achieving the above object, the utility model adopts following scheme: the incubator egg-turning double reduction gear, include small worm, small gear, big worm screw and big worm gear, small worm and small gear engagement, big worm screw and big worm gear engagement, small gear is loaded on the output shaft, small worm and output shaft are contained on the casing, and big worm screw is contained on the bearing with big worm gear, and an end of output shaft connects with the end of big worm screw.

By such scheme as seen because small worm is respectively independently with reaching that big worm screw and big worm gear cooperate cooperating of small gear, to they processing and assembly precision require just can not be higher, like this, will reduce difficulty of processing, and make assemble also comparatively convenient.

The utility model is rational in infrastructure, processing, assembling and easy for installation, low cost of manufacture.

The A of Fig. 2 Fig. 1-A cutaway view;

The B of Fig. 3 Fig. 1-B cutaway view.

Embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, Fig. 2, this incubator egg-turning double reduction gear includes small worm 2, small gear 3, big worm screw 11 and big worm gear 13, small worm 2 and small gear 3 engagements, big worm screw 11 and big worm gear 13 engagements, and small gear 3 is loaded on the output shaft 6.Small worm 2 is contained on the casing 1 with output shaft 6.

As seen from Figure 1, output shaft 6 is contained on the casing 1 by bearing 5, bearing 10, end cap 8, and the end cap 4 that covers output shaft 6 rear ends also is housed on casing 1.One end of output shaft 6 with the mode that the end of big worm screw 11 connects is: be provided with blind hole 11a at the end of worm screw 11 greatly, an end of output shaft 6 stretch among the blind hole 11a and with big worm screw 11 between centers be key connecting.

As seen from Figure 2, small worm 2 is contained on the casing 1 by bearing 14, and the end cap 15, the end cap 16 that cover bearing 14 are housed on casing 1.

Referring to Fig. 1, Fig. 3, big worm screw 11 is contained on the bearing 9 with big worm gear 13, bearing 9 constitutes by two bearing blocks of bearing block 9a, bearing block 9b with support 9c that the diaxon bearing is connected as a single entity, big worm screw 11 is contained on diaxon bearing 9a, the 9b by bearing 10, bearing 12, and big worm gear 13 is loaded on the worm-wheel shaft 17 that is fixed on the support 9c by bearing 18.End cap 19 is equipped with at middle part at big worm gear 13.
