Abstract

The utility model relates to a two-way intermittent type speed variator which is composed of a bevel gear pair which is installed on the middle part of a total transmission shaft, a groove gear pair which is installed on the top end of the total transmission shaft, a half gear pair which is vertically provided with the groove gear pair, etc. The bevel gear pair, the groove gear pair and the half gear pair are all arranged in a box body which has a cover and is dipped in lube, and the composite motion of the bevel gear pair, the groove gear pair and the half gear pair complete tasks of twice 90 DEG turning, intermission and speed changing of a flow production line. The utility model can be widely used for fine dried noodle flow production lines, slaughtering flow production lines, bicycle spraying and baking flow production lines, etc., the utility model has the advantages of small abrasion, fast instantaneous speed for poking deferent objects, non shocking noise, high moving precision, high yield, little possibility of dust pollution, etc., and the utility model is an ideal speed variator for flow production lines.

Description

Two-way intermittent type speed changer

The utility model relates to a kind of gearing, is particularly suitable for using in twice 90 ° of production lines that turn to, as vermicelli production, butcher in the production lines such as operation, bicycle spraying oven dry operation and use.

The structure of the speed changer of using in the above-mentioned production line is different, and the most close with the utility model structure is a kind of gear of noodle production line, comes conversion direction by umbrella gear, realizes speed change by gear pair, finishes intermittent movement by the device of similar cam structure.This dependence gear pair is realized the mode of structure of speed change, makes active and driven gear all be in continuous operating condition, and mechanical wear is big, and it is slow to stir the instantaneous velocity that transmits the thing displacement, causes and transmits under the easy slippage of thing, and yield rate is low; The realization intermittent movement is stirred in timing by similar cam mechanism, and the bump sound pitch has noise, and mechanical wear is serious, and kinematic accuracy is poor, causes the displacement of transmission thing inaccurate, produces phenomenons such as blocking, drop.And these speed change gears mostly are open type, dust pollution, serious wear.

The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of intermittent movement, that mechanical wear is little, to stir the instantaneous velocity that transmits the thing displacement fast and make and transmit thing and be difficult for falling under the slippage, there is not Strike note, kinematic accuracy is high, and the two-way intermittent type speed changer of casing dust-tight is arranged outward.

The purpose of this utility model can realize with following measure: there is driving bevel gear at its total transmission shaft middle part, this top is a driving sheave, adjacent with it is passive sheave, both are by the regularly interior finger transmission of card entry slot, passive sheave is installed on the fluted shaft, there are eccentric rod and driving lever in this outer end, secondary vertically arranged with sheave is half gear pair, passive umbrella gear is installed in the top of half gear driving shaft, successively with driving semi-gear, the initiatively coaxial installation of jam plate, adjacent with it is driven gear and passive jam plate, and both install the back with outside sprocket coaxiality.

The purpose of this utility model also can be perfect by following measure: the groove number of passive sheave is consistent with the shunt line number of production line end; Umbrella gear pair, sheave pair, half gear pair are installed in the casing with cover.

Fig. 1 is the utility model plan view;

Fig. 2 is A-A sectional view of Fig. 1;

Fig. 3 is B-B sectional view of Fig. 1.

The utility model is described in detail below in conjunction with embodiment: the application broad of this speed changer, existing is that example illustrates with the vermicelli production line.Driving bevel gear 12 is installed at the middle part of the total transmission shaft 10 that is driven by the face machine, these axle 10 tops are driving sheaves 4, one of them groove of finger 6 revolutions one circumferential passive sheave 5 on it snaps in once to stir and rotates an angle, thereby drive eccentric rod 2 and driving lever 1 by fluted roller shaft 3, also rotate a respective angles.Secondary vertically arranged with sheave is half gear pair, the top of half gear driving shaft 14 is passive umbrella gear 13, successively with driving semi-gear 15, initiatively jam plate 16 coaxial installations, adjacent with them is driven gear 8 and passive jam plate 7, the back both 8 and 7 with the outside sprocket wheel 11 coaxial installations, when driving semi-gear 15 meshes with driven gear 8, driven axle 9 rotates, drive sprocket wheel 11 motions, when driving semi-gear 15 and driven gear 8 do not mesh, the garden dish type initiatively protuberance of jam plate 16 snaps in the recess of the passive jam plate 7 of garden dish type and locks, thereby makes driven axle 9 that the motion-affecting validity of rotation of disorderly silk can not arranged because of factors such as inertia.Half gear pair has been realized step do not clash into, wearing and tearing are little, precision is high motion.Umbrella gear pair, sheave pair, half gear pair in the whole speed changer all are installed in the casing with cover 17, be immersed in the lubricant oil and reduce wear, three's compound motion realized intermittently, twice 90 ° of flow production lines that turn to, that speed is variable, to adapt to the needs of relevant industries.

The utlity model has mechanical wear little, stir that to transmit the thing instantaneous velocity fast Thereby be difficult for noise, kinematic accuracy height, the transmission of slippage, not bump generation The thing displacement smoothly accurately, yield rate is high and dust is difficult for the advantages such as pollution.
