Worm gear - transmission identification.
On the nameplate, the worm gear ratio is indicated as "and"
If the plate is illegible and the transmission is operational, we rotate the worm to perform a full rotation of the worm wheel. The amount of screw rotation per revolution of the scroll wheel is the ratio. For larger ratios, for example i = 100, you can, for example, make a quarter turn of the scroll wheel and multiply the amount of rotation of the screw by four.
If the plate is illegible and the transmission is inoperative, it is necessary to dismount the auger and worm wheel, count the number of teeth of the scroll wheel and count the snail's multiplicity.
Counting the teeth on the scroll wheel is not a problem. The problem lies in identifying the snail multiplicity. We will explain:
By definition: The snail's helix is the number of starts of the helix of the thread in any cross-section perpendicular to the axis of the screw. Easier: this is the amount of sharp indentations on the cochlea (the points on the line are marked with a circle). Multiplicity is shown in the figure below where each thread turn is marked with a different color.
If the multiplicity is identified, then the translation counts from the formula i = z2 / z1where z2 - number of worm wheel teeth, z1 - snail fold.
The transmission connection defines the diameter of the hole in the drive axis and the diameter of the collar. The motor connection defines the diameter of the shaft and the diameter of the flange. In order for the transmission to be connected to a given motor, its connection must match the motor connection, which means that the diameters of the gearbox and motor shaft have to be of the same diameter and the diameters of the flanges must have the same diameters. It happens that a gear with a smaller shaft is fitted with a gear opening with one degree more, using a so-called reduction sleeve. However, motor flanges must have absolutely identical diameters. Reduction sleeves are widely used to speed up the order.
Measurement to identify connections:
Kacperek, as a Polish manufacturer of gearmotors, produces a series of MR worm gears,
which can be freely modified adapting them to the clients' requirements.
MR gears can be produced in standard versions (with output shaft, side flange, torque arm), but also in special versions upon customer's request
regardless of the quantity.
modifiability
=> version with a propeller shaft used to seat a hand crank or pulley;
=> version with double-sided drive shaft for serial connection of gears with parallel outlet openings;
=> clutch version for connecting the gear unit to the motor with a torsionally flexible coupling, ensuring a soft start and misalignment compensation;
=> version from outlets with a special shape and metric or inch dimensions;
=> version with a left-turn screw for symmetrical cooperation with the version with the right-hand screw;
=> Viton seals at the entrance and exit of the gear;
=> possible to use synthetic oil, oils for specific working conditions including low temperatures, cooking oil;
=> parts of gears made of custom materials e.g. monolithic bronze scroll wheel, steel scroll hub, stainless steel components etc. and other special versions on request.
MR worm gears are produced with the highest precision and carefully selected materials of the best grade, thanks to which an extremely high durability of the whole element and its individual parts has been achieved. Thanks to the extensive assortment offer and professional engineering and technical background it is possible to adapt the designs of gearmotors (worm gears) MR to individual customer requirements.
Before using or storing transmission gears manufactured by Kacperek, please read the accompanying instructions in detail Technical Documentation.
