Description
Technical field
The utility model relates to technical field of mechanical transmission, is specifically related to a kind of transmission joint.
Background technique
At present, some equipment main transmission has been coordinated with equipment transmission main shaft by worm-gear speed reducer.When worm-gear speed reducer coordinates too tight in transmission main shaft, the later stage is easily caused to change dismounting difficulty.When being combined with gap, the flute profile cam quality on equipment is comparatively large, produces and impacts, make main shaft, worm-gear speed reducer rapid wearing in operation process to main drive shaft.
Summary of the invention
In order to solve above-mentioned prior art Problems existing, the utility model provides a kind of transmission joint, and this apparatus structure is simple, and installation and removal are convenient, and long service life.
Realizing the technological scheme that the utility model above-mentioned purpose adopts is:
A kind of transmission joint, at least comprise axle sleeve A, axle sleeve B, expansion sleeve and minor axis, axle sleeve A is sleeved on minor axis, axle sleeve A and minor axis are integral type structure, axle sleeve B is sleeved on expansion sleeve, axle sleeve A is axially evenly distributed with at least two through holes along axle sleeve A, transmission shock absorbing sleeve is installed in each through hole, axle sleeve B is axially evenly distributed with position along axle sleeve B, the transmission straight pin that number is corresponding with transmission shock absorbing sleeve, each transmission straight pin is arranged in each transmission shock absorbing sleeve respectively, the transmission shock absorbing sleeve interference fit that each transmission straight pin is corresponding with this transmission straight pin, axle sleeve A is provided with a locating stud, axle sleeve B is provided with the position pin-and-hole corresponding with locating stud, locating stud is installed in pin-and-hole, it is interference fit between locating stud and pin-and-hole, the material of transmission shock absorbing sleeve is polyoxymethylene.
Described through hole, transmission shock absorbing sleeve and transmission straight pin are equipped with 6.
Minor axis is the minor axis of band key.
Compared with prior art, its beneficial effect and advantage are the utility model:
1) this device is detachable, installs simple and convenient, change and keep in repair very convenient with worm-gear speed reducer, equipment connection.
2) worm gear of this device and worm-gear speed reducer and equipment input shaft coordinate tight, little to the wearing and tearing of worm-gear speed reducer and equipment input shaft, this device has been used to increase substantially the working life of worm-gear speed reducer and equipment, this device self wearing and tearing are simultaneously also very little, long service life.
Accompanying drawing explanation
The structural representation of the transmission joint that Fig. 1 provides for the utility model.
Wherein, 1-minor axis, 2-axle sleeve A, 3-locating stud, 4-transmission shock absorbing sleeve, 5-axle sleeve B, 6-expansion sleeve, 7-pin-and-hole, 8-transmission straight pin, 9-transmission main shaft.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
As shown in Figure 1, this device at least comprises axle sleeve A2, axle sleeve B5, expansion sleeve 6 and minor axis 1 to the structure of the transmission joint that the utility model provides.Axle sleeve A2 is sleeved on minor axis 1, and axle sleeve A2 and minor axis 1 are integral type structure.In the present embodiment, minor axis 1 is the axle of band key, for key is connected between minor axis and the worm gear of worm reduction gear, strengthens being fixedly connected with between minor axis with worm gear further.This device, to the worm gear of worm reduction gear assembling minor axis, is avoided the output shaft damaging worm reduction gear, is made troubles to the maintenance of worm reduction gear.Axle sleeve B5 is sleeved on expansion sleeve 6, and expansion sleeve 6 is sleeved on transmission main shaft 9, plays a protective role to transmission main shaft.
Axle sleeve A2 is axially evenly distributed with at least two through holes along axle sleeve A, transmission shock absorbing sleeve 4 is installed in each through hole, axle sleeve B5 is axially evenly distributed with position, the number transmission straight pin 8 corresponding with transmission shock absorbing sleeve along axle sleeve B, each transmission straight pin 8 is arranged in each transmission shock absorbing sleeve 4 respectively, transmission shock absorbing sleeve 4 interference fit that each transmission straight pin 8 is corresponding with this transmission straight pin.In the present embodiment, described through hole, transmission shock absorbing sleeve and transmission straight pin are equipped with 6.The polyformaldehyde material that transmission shock absorbing sleeve 4 adopts damping wear-resisting.Axle sleeve A2 is provided with more than one locating stud 3, and axle sleeve B5 is provided with the position pin-and-hole corresponding with locating stud 7, and locating stud 3 is installed in pin-and-hole 8, interference fit between locating stud and pin-and-hole.Transmission shock absorbing sleeve adopts polyformaldehyde material, the shock absorbing sleeve that the transmission shock absorbing sleeve that polyformaldehyde material is made is made compared with rubber material, and polyformaldehyde material hardness is large, dimensionally stable, and wear resistance is good.Because polyoxymethylene size hardness is large, dimensionally stable, inserts in transmission shock absorbing sleeve for convenience of by transmission straight pin, axle sleeve A establishes a locating stud, while locating stud location, transmission straight pin, naturally to the transmission shock absorbing sleeve of upper correspondence, directly inserts in transmission shock absorbing sleeve.And, due to the dimensionally stable of polyformaldehyde material, there is the phenomenon of radial deflection in the input shaft (i.e. driven shaft) that there is not equipment in transmission process, and the shock absorbing sleeve that existing great majority are made with rubber material, not only not wear-resisting, and easily there is the phenomenon of driven shaft radial deflection.
This device due to axle sleeve A and minor axis be integral type structure, between axle sleeve B and transmission main shaft, expansion sleeve is installed, therefore during with this device connection device and worm reduction gear, the most easy to wear is transmission shock absorbing sleeve, only need to change shock absorbing sleeve, not only easy to operate, and reduce cost of production.
