Abstract
The utility model worm-cam retarder belongs to the retarder field, it is by reduction case, worm-cam and roller dish are formed, worm-cam and roller dish fit engagement, the roller dish is radially distributed with two above cylindrical rollers on the end face circumference, the engagement of two cylindrical rollers and worm-cam is arranged in rotary course all the time, the worm-cam rotation, the worm-cam working surface promotes the roller dish and rotates, because the different spaces curved surface of worm-cam working surface, the roller dish can be done continuously or interrupted division; The utility model is simple in structure, long service life, and stable working is reliable, can replace indexing mechanism, is suitable for the highi degree of accuracy rotation.
Description
Affiliated field
The utility model worm-cam retarder belongs to the retarder field.
Technical background
Using the reducer structure form now generally all is to adopt gear reducer, worm gear and worm screw also are the reducer structures of using always, existing reducer structure can only slow down, can not realize calibration, particularly can not realize continuous and interrupted division, in high-precision processing, need to realize continuously or interrupted division, use reducer structure to satisfy the demands now.
The model utility content
The purpose of this utility model is to avoid the deficiencies in the prior art part and provides a kind of simple in structure, and the efficient height can be realized continuously or interrupted division, is suitable for the worm-cam retarder that the highi degree of accuracy rotation requires.
The purpose of this utility model reaches by following measure, it is by reduction case, worm-cam and roller dish are formed, worm-cam and roller dish fit engagement, the roller dish is radially distributed with the several cylinders roller on the end face circumference, the engagement of two cylindrical rollers and worm-cam is arranged in rotary course all the time, the worm-cam rotation, the worm-cam working surface promotes the roller dish and rotates, because the different spaces curved surface of worm-cam working surface, the roller dish can be done continuously or interrupted division.
Roller dish of the present utility model is at the cylindrical roller that is radially distributed with on the end face circumference more than 5.
Roller of the present utility model is made up of roller sleeve and roller shaft, roller sleeve is installed on the roller shaft, and roller shaft is installed on the roller dish end face circumference, and roller sleeve can be rotated on roller shaft, in cylindrical roller and the worm-cam engagement process, roller sleeve is to roll on the worm-cam working surface.Roller sleeve can adopt bearing.
The track that moves axially of worm-cam working surface upper curve is to calculate gained according to equation,
The utility model is simple in structure, long service life, and stable working is reliable, can replace indexing mechanism, is suitable for the highi degree of accuracy rotation.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structural representations of the present utility model.
Accompanying drawing 3 is worm-cam structural representations of the present utility model.
Accompanying drawing 4 is roller structure schematic representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in accompanying drawing 1, accompanying drawing 2, it is by reduction case 1 for the utility model, worm-cam 3 and roller dish 2 are formed, worm-cam and roller dish fit engagement, the roller dish is radially distributed with 12 cylindrical rollers 4 on the end face circumference, the engagement of two cylindrical rollers and worm-cam is arranged in rotary course all the time, the worm-cam rotation, the worm-cam working surface promotes the roller dish and rotates, because the different spaces curved surface of worm-cam working surface, the roller dish can be done continuously or interrupted division.
As shown in Figure 3, the working surface of worm-cam 3 of the present utility model is by reference surface A and B, when worm-cam rotates, because the difference of the working curved surface of cam can realize the continuous or interrupted division of roller dish.The track that moves axially of worm-cam working surface upper curve is to calculate gained according to equation.
As shown in Figure 4, roller of the present utility model is made up of roller sleeve 5 and roller shaft 7, roller sleeve is to adopt bearing, roller sleeve is installed on the roller shaft, roller shaft is installed on the roller dish end face circumference, and in cylindrical roller and the worm-cam engagement process, roller sleeve is to roll on the worm-cam working surface, pad 6 is installed, restriction and fixing roller sleeve on roller shaft.
Claims (4)
1, a kind of worm-cam retarder, it is characterized in that by reduction case worm-cam and roller dish are formed, worm-cam and roller dish fit engagement, the roller dish is radially distributed with cylindrical roller on the end face circumference, the engagement of two cylindrical rollers and worm-cam is arranged in rotary course all the time.
2, worm-cam retarder according to claim 1 is characterized in that roller is made up of roller sleeve and roller shaft, and roller sleeve is installed on the roller shaft, and roller shaft is installed on the roller dish end face circumference, and roller sleeve can be rotated on roller shaft.
