Abstract
The utility model relates to a gapless worm-gear speed reducer for wood-working mechanical equipment, which comprises a box and a transmission component arranged in the box. An input flange is mounted on one side of the box, an output pressure cover is mounted on the other side of the box, and the transmission component comprises a double-lead worm, a worm gear and an output shaft. The double-lead worm is meshed with the worm gear, one end of the double-lead worm is connected with the inner wall of the box through a first bearing, the other end of the double-lead worm is mounted in the input flange through a second bearing, one end of the output shaft is in mechanical transmission connection with the worm gear, and the other end of the output shaft is connected with the output pressure cover through a third bearing and extends out of the output pressure cover. By means of double-lead worm transmission, the speed reducer can be stable in operation, and if a transmission gap is widened due to abrasion in use of the speed reducer, a worm-gear transmission pair can recover to an initial lead and the original precision only by adjusting the axial position of the worm without replacing a new worm and a new worm gear.
Description
Technical field
The utility model relates to worm and worm gear speed reducer structure, is specifically related to a kind of woodworking machinery equipment and uses the worm and worm gear speed reducer.
Background technique
The worm-gear speed reducer that present woodworking machinery equipment is used is a kind of compact structure that has, and velocity ratio is big, and the gearing that has auto-lock function under certain condition, is one of the most frequently used speed reducer.But, be unfavorable for mechanical circular movement precision drive owing to after the worm and wheel wearing and tearing, can cause the increasing of worm and wheel back lash.
The model utility content
In order to overcome the deficiency of existing technology, the purpose of the utility model has been to propose that a kind of cost is low, the woodworking machinery equipment of long service life is with no clearance type worm and worm gear speed reducer.
In order to achieve the above object, the technological scheme that the utility model adopted is following:
A kind of woodworking machinery equipment is with no clearance type worm and worm gear speed reducer; Comprise casing and be arranged at the transmitting assemblies in the casing, a side of casing is equipped with input flange, and the opposite side of casing is equipped with the output gland; Said transmitting assemblies comprises two helical pitch worm screws, worm gear and output shaft; Two helical pitch worm and wheel engagements, the end of two helical pitch worm screws is connected with the inwall of casing through clutch shaft bearing, and the other end of two helical pitch worm screws passes through second Bearing Installation in input flange; One end and the worm gear machinery of output shaft are in transmission connection, and the other end of output shaft is connected with the output gland through the 3rd bearing and stretches out in the output gland.
As preferred construction, clutch shaft bearing is a tapered roller bearing.
As preferred construction, second bearing is a deep groove ball bearing.
As preferred construction, the 3rd bearing is a deep groove ball bearing.
The utility model compared with prior art adopts two helical pitch worm drive, controls the back lash of worm and wheel effectively; Make speed reducer steady in the running, if cause drive gap to increase because wear and tear in the use, as long as at this moment adjust the axial position of worm screw; Can make the Worm and Worm Gear Driving pair return to initial helical pitch and revert to original precision; Do not need the worm screw, the worm gear that more renew, very economic, practical, cost is low, the effect of long service life thereby reach.
Description of drawings

Fig. 2 is that the P of Fig. 1 is to schematic representation.
Wherein, 1, casing; 2, two helical pitch worm screws; 3, input flange; 4, second bearing; 5, output gland; 6, output shaft; 7, the 3rd bearing; 8, worm gear; 9, clutch shaft bearing.
Embodiment
Below, in conjunction with accompanying drawing and embodiment, the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.
As depicted in figs. 1 and 2, a kind of woodworking machinery equipment is with no clearance type worm and worm gear speed reducer, and it comprises casing 1 and is arranged at the transmitting assemblies in the casing 1.
One side of casing 1 is equipped with input flange 3, and the opposite side of casing 1 is equipped with output gland 5.Said transmitting assemblies comprises two helical pitch worm screws 2, worm gear 8 and output shaft 6; Two helical pitch worm screws 2 and worm gear 8 engagements; The end of two helical pitch worm screws 2 is connected with the inwall of casing 1 through clutch shaft bearing 9; The other end of two helical pitch worm screws 2 is installed in the input flange 3 through second bearing 4, and an end and the worm gear machinery of output shaft 6 are in transmission connection, and the other end of output shaft 6 is connected and stretches out in output gland 5 through the 3rd bearing 7 exports gland 5.
As preferred construction, the clutch shaft bearing 9 of present embodiment adopts tapered roller bearing; Second bearing 4 adopts deep groove ball bearing; The 3rd bearing 7 also adopts deep groove ball bearing.
Present embodiment also has following characteristics:
1, casing adopts the HT250 material of band muscle, through the finite element analysis principle, makes product rigidity good, and intensity is high, compact mechanical structure, and the life-span is long;
2, install simple and easy, adopt hollow output shaft, make connect pattern flexibly, superior performance, be easy to Maintenance and Repair;
3, operate steadily, noise is little, durable in use;
4, worm gear adopts split type the connection with output shaft, and employing and iron core are integrated poured during cast copper, have reduced manufacture cost widely;
Fit tolerance adopted interference fit when 5, worm gear connected with working machine with hollow output shaft and hollow output shaft, and is steady in the time of can making the working machine running, avoids working machine when stopping and causing worktable " to rock ";
6, worm screw and one-level gear material all adopt 20CrMnTi, and heat treatment is whole carbonitriding, and gear and worm screw thread are after grinding, and precision can reach 6 grades; Worm gear adopts the stronger KK copper of wear resistance simultaneously, and transmission efficiency, working life and bearing capacity are improved greatly;
7, worm and gear adopts two helical pitch transmissions, can be through axially adjustment worm gear and worm meshing gap, and it is big to adjust the back lash of causing because of worm gear wearing and tearing when the work effectively, realization " zero clearance engagement ";
8, when the design worm and gear, lead angle is little, can realize complete self-locking, avoids working machine in operation process, to have the phenomenon of counter-rotating to take place;
9, because the sideshake of worm and wheel can be controlled within the reasonable range effectively, remain correct meshing relation; And compact structure, easy to adjust, thereby in the structure that requires continuously accurate calibration, extensively adopted, applicability is strong, and safety reliability is big.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technological scheme and the design of above description.
