Gear and rack floating clearance transmission device and gear and rack transmission device

Abstract

The invention discloses a gear and rack floating clearance transmission device which is used on a gear and rack transmission facility. The transmission track of a guide device of the transmission device is a line or a large radian. The transmission device comprises a supporting module, a driving module, a gear and rack module and a clearance eliminating module, wherein the supporting module is fixed to a sliding block of the guide device, and the sliding block slides along the guide device; the driving module is fixed to the supporting module and is used for outputting the driving force of thegear and rack floating clearance transmission device sliding along the guide device; the gear and rack module is connected with the drive module and is used for driving the gear and rack floating clearance transmission device to slide along the guide device; and the clearance eliminating module is fixed to the supporting module and is used for eliminating the engagement clearance between a gear and a rack. By means of the gear and rack floating clearance transmission device and a rack transmission device, the requirement for the machining precision of the gear part is lowered, the requirementfor the installation precision of the mutual positions of a sliding unit and a transmission unit is also lowered, the service life is long, the cost is reduced, and the adaptability of a production line to the environment is also improved.

Description

technical field [0001] The invention relates to industrial automatic transmission equipment, in particular to a rack and pinion floating anti-backlash transmission device. Background technique [0002] The production line of modern industry tends to be more and more unmanned, and the core of the assembly line lies in the transmission. The assembly line is covered with various transmission mechanisms. The more complex the production line, the longer the transmission distance, that is, the longer the transmission stroke. Among them, the gear and rack transmission is a relatively common transmission method, but if the meshing of the gear and the rack is not tight enough, if there is a gap, it will cause errors in the transmission stroke, and at the same time, the wear between the gear and the rack will also Therefore, in modern automatic assembly lines, failures and unnecessary wear often occur due to excessive meshing gaps between gears and racks, which not only increases main...

[0002] The production line of modern industry tends to be more and more unmanned, and the core of the assembly line lies in the transmission. The assembly line is covered with various transmission mechanisms. The more complex the production line, the longer the transmission distance, that is, the longer the transmission stroke. Among them, the gear and rack transmission is a relatively common transmission method, but if the meshing of the gear and the rack is not tight enough, if there is a gap, it will cause errors in the transmission stroke, and at the same time, the wear between the gear and the rack will also Therefore, in modern automatic assembly lines, failures and unnecessary wear often occur due to excessive meshing gaps between gears and racks, which not only increases maintenance costs, but also delays the normal progress of production and affects economic benefits

[0003] The prior art is achieved by improving the processing accuracy of the gear parts, and improving the installation accuracy of the mutual position of the sliding unit and the transmission unit. However, due to the wear of the gear parts and the loosening of the fastening parts, it is easy to occur. Therefore, this The thankless treatment method not only increases the purchase and maintenance costs of the production line, but the effect is not significant. This has become a major pain point in the field of industrial automation
