Abstract

The utility model relates to a speed reducer, in particular to a hard gear surface fully sealed energy-saving planet speed reducer applicable to an environment-friendly water treatment screw pump. The speed reducer is characterized in that based on the prior speed reducer structure, the speed reducer integrates a mounting flange and a frame into a whole; and a first rolling bearing adopting a fully sealed bearing is combined with a seal ring to form a fully sealed structure. A working machine can be directly mounted on a planet reducing mechanism through the mounting flange, so that a transmission device is saved, the complete machine volume is reduced, and the use cost is reduced; a cylindrical pin arranged on an output shaft transfers moment to the working machine, thereby achieving the convenient, safe and reliable assembly; the fully sealed disposable lubrication technology is adopted to ensure that the speed reducer does not require lubricant filling or replacement until working over 5000 hours, so that the routine maintenance of the speed reducer is simple and feasible.

Description

The hard energy-conservation speed reducer of the hermetically sealed planet of the flank of tooth

Technical field

The utility model relates to the machinery that slows down, and particularly is applicable to the energy-conservation speed reducer of the hermetically sealed planet of a kind of hard flank of tooth of environmental protection water treatment screw pump.

Background technique

Planetary speed reducer is a speed reducer commonly used in the mechanical transmission, common planetary speed reducer output terminal is the cylinder axis of a band keyway, to be installed on the base respectively with work mechanism in use, overlap transmission device as band transmission or chain-driven by one again, just can make the work mechanism running, therefore, occupation space is bigger, a subsidiary cover transmission device is absolutely necessary, and has also just increased user cost; In addition, former lubricating system generally all is open, needs often filling or changes oiling agent, and when the occasion of maintaining inconvenience was used, it was cumbersome just to seem.

The model utility content

The purpose of this utility model is at above-mentioned defective, a kind of compact structure, easy to use, economical with materials is provided, dwindles and take up room and the energy-conservation speed reducer of the hermetically sealed planet of the hard flank of tooth that maintaining is simple.

The technical solution of the utility model is the energy-conservation speed reducer of the hermetically sealed planet of the hard flank of tooth, comprise motor 1, motor reel 2, planetary gear speed reducing mechanism, first rolling bearing 8, hole back-up ring 9, support 10, second rolling bearing 11, shaft block ring 12, seal ring 13, output shaft 14, it is characterized in that:

A, said support 10 are made one with mounting flange 18;

B, said first rolling bearing 8 are that hermetically sealed bearing combines the formation all-sealed structure with seal ring 13.

Said mounting flange 18 is provided with 4-12 screw that is used for installment work machinery; Said output shaft 14 is provided with the straight pin (15) to the work mechanism transmission torque.

Said straight pin 15 is 3-6 μ m with the matching gap of pin-and-hole.

Advantage of the present utility model: the one, because support and mounting flange are made one, work mechanism can be directly installed on the planetary speed reducer, saved a cover transmission device, also dwindled the shared space of complete machine; The 2nd, the planetary speed reducer output shaft adopts straight pin to the work mechanism carry-over moment, and is easy to assembly and safe and reliable; The 3rd, the hermetically sealed disposable lubrication technology of the lubricated employing of planetary gear speed reducing mechanism can guarantee that planetary gear speed reducing mechanism needn't annotate or change oiling agent in 5000 hour operating time, makes the daily maintenance work of speed reducer simple.

Fig. 1 is a structural representation of the present utility model.

Embodiment

Further specify embodiment below in conjunction with accompanying drawing.

With reference to Fig. 1,1-motor, 2-motor reel, 3-gear ring base, 4-ring gear, 5-planet wheel, 6-guide, 7-bearing pin, 8-first rolling bearing, 9-hole back-up ring, 10-support, 11-second rolling bearing, 12-shaft block ring, 13-seal ring, 14-output shaft, 15-straight pin, 16-the 3rd rolling bearing, 17-sun gear, 18-mounting flange.As shown, planetary gear speed reducing mechanism comprises gear ring base 3, ring gear 4, planet wheel 5, guide 6, bearing pin 7, the 3rd rolling bearing 16 and sun gear 17.Overall structure is as follows: motor 1 and gear ring base 3 and support 10 are connected by fastening piece, and sun gear 17 keys are connected on the motor reel 2, and motor reel 2 ends are by 16 supportings of the 3rd rolling bearing; Planet wheel 5 and sun gear 17 outer gearings mesh guide 6 and planet wheel 5 secure fit simultaneously with in the ring gear 4; Bearing pin 7 and output shaft 14 secure fit are again with 6 movable cooperations of guide; First rolling bearing 8 and second rolling bearing, 11 supporting output shafts 14; The hole limits the axial position of second rolling bearing 11 with back-up ring 9 and shaft block ring 12, the seal ring 13 and first rolling bearing 8 are born the effect of sealing planetary speed reducer inner chamber, and first rolling bearing 8 is that hermetically sealed bearing combines the all-sealed structure that constitutes planetary gear speed reducing mechanism with seal ring 13; Straight pin 15 is born the effect to the work mechanism transmission torque.When motor reel 2 drove sun gear 17 rotations, planet wheel 5 was revolving round the sun around sun gear 17 in bearing pin 7 rotations, and the revolution motion of planet wheel 5 drives output shafts 14 by bearing pin 7 and rotates, thereby finished the gearing down process of planetary speed reducer.To take up room in order reducing, to save a cover transmission device, save manufacture cost, also saved electric energy simultaneously, support 10 and mounting flange 18 are made one, so mounting flange 18 is provided with 4-12 screw that is used for installment work machinery; In order to make planetary gear speed reducing mechanism reliably to the work mechanism transmission torque, output shaft 14 is provided with straight pin 15, straight pin 15 is 3-6 μ m with the matching gap of pin-and-hole, has changed original keyway connecting structure, so just makes easy to assembly and safe and reliable to operation.In order to strengthen the greasy property in the planetary gear speed reducing mechanism, adopt all-sealed structure, first rolling bearing 8 is adopted hermetically sealed bearing, constitute in conjunction with the seal ring on the output shaft 14 13, make and only add a lubricant oil in the planetary gear speed reducing mechanism and just can move 5000 hours, just needn't annotate in the meantime or oil change more, make the daily maintenance work of this machine simple.
