Abstract

The utility model discloses a worm gear reducer which comprises a worm gear motor, a driving worm, a driven worm, fixed plates and worm gears. The worm gear motor is connected with the driving worm through a main coupling, the driving worm is connected with the driven worm through an auxiliary coupling, the front end of the worm gear motor is fixedly connected with the fixing plates, the fixed plates are in screw joint and are fixed through fixing seats, the worm gears are arranged below the fixed plates, the lower ends of the worm gears are connected with worm gear shafts, the worm gears are meshed with the driven worm through gears, and the worm gear shafts are fixedly connected with rotating vane flashboards. Due to the fact that multiple fixed plates can be spliced, the driven worm can be lengthened through the auxiliary coupling, and therefore the worms can be lengthened or shortened according to the change of a working environment, the work adaptive range of a machine is increased, and when the worm gears or the driven worm needs to be maintained or replaced, the operation is convenient, and cost is reduced.

Description

Worm type of reduction gearing

Technical field

The utility model relates to a kind of retarder, is specifically related to a kind of worm type of reduction gearing.

Background technique

Retarder plays coupling rotating speed and transmitting torque between prime mover and working machine or actuator, use very extensive in modern mechanical.Retarder can be divided into universal speed reducer and professional retarder two large classes by purposes, mainly comprises gear reducer, worm reducer, gear-worm reducer, planetary reducer etc.Present domestic general worm type of reduction gearing, often utilizing a worm screw to connect a plurality of worm gears increases work efficiency, but this kind worm type of reduction gearing often is difficult to lengthen the length of being interrupted worm screw according to the conversion of working environment, adaptability is relatively poor, and keep in repair loaded down with trivial detailsly, can't carry out repair and replacement to single worm gear.

The model utility content

The purpose of this utility model is to overcome deficiency of the prior art, and provide a kind of and lengthen or shorten worm screw, and the worm type of reduction gearing of low production cost.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of worm type of reduction gearing, comprise worm gear reducer motor, main worm screw, from worm screw, fixed plate and worm gear, described worm gear reducer motor links to each other with main worm screw by lead spindle, described main worm screw connects from worm screw by the duplicate invoice axial organ, described worm gear reducer motor front end is fixedly connected with the polylith fixed plate, be spirally connected by fixed base between the described fixed plate fixing, described fixed plate is arranged with worm gear, described worm gear lower end is connected with worm-wheel shaft, described worm gear with mesh by gear from worm screw, described worm-wheel shaft is fixedly connected with the rotating vane flashboard.

The utility model can a plurality ofly splice owing to fixed plate, can lengthen by the duplicate invoice axial organ from worm screw, therefore can lengthen or shorten worm screw according to the variation of working environment, improve the work accommodation scope of machine, and need repairing or when changing when worm gear or from worm screw, make things convenient for operation, reduced cost.

Description of drawings

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

Fig. 2 is the plan structure schematic diagram of Fig. 1;

Fig. 3 is the right elevation of Fig. 1.

Marginal data: 1, worm gear reducer motor; 2, lead spindle; 3, main worm screw; 4, from worm screw; 5, duplicate invoice axial organ; 6, fixed plate; 7, worm gear; 8, worm-wheel shaft; 9, rotating vane flashboard; 10, fixed base.

Embodiment

Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.

Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of worm type of reduction gearing of the present embodiment, comprise worm gear reducer motor 1, main worm screw 3, from worm screw 4, fixed plate 6 and worm gear 7, described worm gear reducer motor 1 links to each other with main worm screw 3 by lead spindle 2, described main worm screw 3 connects from worm screw 4 by duplicate invoice axial organ 5, described worm gear reducer motor 1 front end is fixedly connected with polylith fixed plate 6, be spirally connected fixing by fixed base 10 between the described fixed plate 6, described fixed plate 6 is arranged with worm gear 7, described worm gear 7 lower ends are connected with worm-wheel shaft 8, described worm gear 7 with from worm screw 4 by the gear engagement, described worm-wheel shaft 8 is fixedly connected with rotating vane flashboard 9.

The utility model is when work, 1 operation of worm gear reducer motor, driving main worm screw 3 rotates, mesh worm gear 7 from worm screw 4 by gear, worm gear 7 reduces by rotating speed after the transmission of gear, worm gear 7 drives rotating vane flashboard 9 and rotates, when the working environment variation, when needing to prolong worm screw, fixed plate 6 lengthens by fixed base 10, lengthen by duplicate invoice axial organ 5 from worm screw 4, therefore can lengthen or shorten worm screw according to the variation of working environment, improve the work accommodation scope of machine, and need repairing or when changing when worm gear 7 or from worm screw 4, make things convenient for operation, reduced cost.
